Local authorities and <strong>IIP</strong> guests during the Institute official inauguration<br />
<strong>IIP</strong> inaugurates new building inside campus<br />
After three years of work<br />
the new building of the<br />
International Institute of<br />
Physics of the Federal University<br />
of Rio Grande do<br />
Norte (<strong>IIP</strong>-UFRN) was inaugurated<br />
last March 21 in a<br />
special ceremony, attended<br />
by local authorities and<br />
members of the Brazilian<br />
and international scientific<br />
community. The new<br />
building will provide de<br />
<strong>IIP</strong> with a better infrastructure<br />
and allow the institution<br />
to host its own events<br />
inside its facilities.<br />
“This new space will allow<br />
us to host an even bigger<br />
number of scientific events<br />
for a longer period of time<br />
and bring more scientists<br />
to work in Natal. This facility<br />
is unlike any other that<br />
I have ever seen in Brazil”,<br />
said the <strong>IIP</strong> Director, Professor<br />
Alvaro Ferraz.<br />
The construction started in<br />
2013 and covers over 4.000<br />
square meters. The building<br />
has an auditorium with<br />
148 seats, two seminar<br />
rooms, three discussion<br />
rooms, a high processing<br />
data laboratory, and more<br />
comfortable offices for researchers.<br />
Inauguration<br />
During the opening ceremony<br />
a crowded auditorium<br />
had the opportunity<br />
to watch a special presentation<br />
by the string quartet<br />
group “Café Quarteto”,<br />
from the University´s Music<br />
Department.<br />
The Rector Angela Paiva<br />
reinforced the commitment<br />
of UFRN with the <strong>IIP</strong>,<br />
and her personal pleasure<br />
to see the building concluded.<br />
According to Professor Paiva,<br />
the open interchange<br />
of renowned scientists in<br />
the university, enabled by<br />
the institute, and the high<br />
quality of the work presented<br />
by its researchers<br />
are just some of the benefits<br />
brought to the local<br />
scientific community by<br />
the <strong>IIP</strong> activities.<br />
Representing the post<br />
doctor researchers, Dr. Fabio<br />
Novaes addressed the<br />
present guests, and spoke<br />
about his career as a physicist<br />
and his experience as<br />
post-doctor at the <strong>IIP</strong>.<br />
The <strong>IIP</strong> goes further in the<br />
objective of forming new<br />
researchers. They put us<br />
in contact with some of<br />
the main research leaders<br />
of the world, who are<br />
happy to start new collaborations<br />
with us. I consider<br />
myself very lucky<br />
for having this kind of<br />
international experience<br />
inside my own country”,<br />
said Novaes.<br />

Workshop Physics and Mathematics of Complex Systems<br />
Physicists and Mathematicians<br />
were gathered<br />
at the <strong>IIP</strong> for two<br />
weeks, in a series of presentations<br />
and debates<br />
regarding challenges<br />
common to both sciences.<br />
The workshop “Physics<br />
and Mathematics<br />
of Complex Systems:<br />
Growing Interfaces,<br />
Nonlinear Dynamics,<br />
Integrability”, hosted<br />
from April 04 to 15, was<br />
the first major scientific<br />
event to take place<br />
at the new <strong>IIP</strong> building,<br />
and was organized<br />
to promote a unique<br />
synergy of expertise in<br />
physics, as well as in applied<br />
and pure mathematics,<br />
in order to tackle<br />
important theoretical<br />
challenges in non-equilibrium.<br />
According to Professor<br />
Boris Dubrovin, from<br />
SISSA, the event was a<br />
special opportunity to<br />
exchange experiences<br />
with colleagues from a<br />
different science.<br />
“I enjoyed very much<br />
this conference. It<br />
was mainly centered<br />
in physics. I am not a<br />
physicist, I am a Mathematician,<br />
nevertheless<br />
2016 IAC Meeting<br />
I am very interested<br />
in looking into what<br />
physicists do and in<br />
collaborating with<br />
them”, said Professor<br />
Dubrovin.<br />
The local scientific<br />
community, as well as<br />
representatives from<br />
other institutions in<br />
Brazil, were also present<br />
to the event, when<br />
they had the opportunity<br />
to interact with<br />
senior researchers.<br />

IAC members during the first day of meeting<br />
The <strong>IIP</strong>’s International<br />
Advisory Council (IAC)<br />
was reconvened from<br />
March 21 to 22, in order<br />
to discuss the directives to<br />
be taken by the Institute in<br />
its 2017 calendar, as well<br />
as to analyze the results<br />
achieved in the scientific<br />
events of 2015. The IAC<br />
meeting is hosted once<br />
a year by the <strong>IIP</strong>, and is<br />
composed by renowned<br />
physicists from Brazil and<br />
abroad.<br />
As one of the results from<br />
this year meeting , a set<br />
of events has already<br />
been pre-approved for<br />
next year, including<br />
schools, workshops, and<br />
symposiums on theoretical<br />
physics and related areas.<br />
The event was hosted<br />
during the Inauguration<br />
of the new <strong>IIP</strong> building,<br />
so the counselors could<br />
be present during the<br />
ceremony that delivered<br />
the new installations.<br />
“This year’s meeting was<br />
very special for us, as it<br />
was the first time that our<br />
council was assembled<br />
in our own building. We<br />
worked very hard to<br />
be here today and the<br />
contribution of each IAC<br />
member was essential<br />
for this to happen”, said<br />
Professor Alvaro Ferraz, <strong>IIP</strong><br />
Director.

Interview with<br />
Prof. Rodrigo Pereira<br />
Born in Sete Lagoas, Brazil, Rodrigo Pereira had an interest in science since<br />
elementary school and in high school decided to pursue a career in Physics<br />
because of the influence of one of his teachers. After his PhD and spending<br />
sometime in renowned scientific institutions in Brazil and abroad, he is now a full<br />
Professor at the <strong>IIP</strong> where he will work with Strong Correlated Electron Systems.<br />
In this interview he talks a little more about his work and expectations for the<br />
future of his research in Natal.<br />
ProfessorRodrigo Pereira in his office at the <strong>IIP</strong><br />
<strong>IIP</strong> NEWS - Tell us a little bit about<br />
your career in physics.<br />
PROF. RODRIGO PEREIRA - I did my<br />
undergrad and my masters at UNI-<br />
CAMP, and after that, in 2004 I went<br />
to Canada. I did my PhD at the University<br />
of Britsh Columbia, working<br />
with Professor Ian Affleck, and after<br />
that I did a post-doc at the Kavli Institute<br />
for Theoretical Physics (USA)<br />
for two years.<br />
Since 2010 I’ve been back in Brazil,<br />
working in São Carlos, at the University<br />
of São Paulo and today I’m here<br />
for my first day at the <strong>IIP</strong>.<br />
I have always worked in condensed<br />
matter physics, strongly correlated<br />
systems, so I’m mainly interested in<br />
applications of field theory matters<br />
to strongly correlated systems. I do<br />
a lot of work on one dimensional<br />
systems, using techniques like bosonisation,<br />
conformal field theories,<br />
sometimes exact methods for integrable<br />
models, but I am also interested<br />
in understanding what one<br />
can measure in an experiment, so at<br />
the same time I try to explain some<br />
physical properties in materials.<br />
<strong>IIP</strong> NEW - When did you first develop<br />
an interest in science?<br />
Photo by Cyro Lucas Souza<br />
PROF. RODRIGO PEREIRA - I guess<br />
that it was in elementary school. I<br />
was always a bit curious about science,<br />
I was always reading a lot and<br />
trying to understand things, but it<br />
was really in high school that I decided<br />
that I wanted to study physics.<br />
I was very much influenced by a very<br />
good physics teacher that I had. He<br />
started telling me some stuff beyond<br />
what we were learning in school, so I<br />
thought that was interesting.<br />
Since I lived in a small town I had no<br />
idea of what a physicist did at the<br />
time, but I was very interested so I<br />
had decided that I wanted to study<br />
physics.<br />
<strong>IIP</strong> NEWS - And when did you decide<br />
to pursue a career as a researcher?<br />
PROF. RODRIGO PEREIRA - I guess<br />
I tried to give my small contribution<br />
to this bigger enterprise of human<br />
knowledge and how we try to understand<br />
the world around us and<br />
for me the most interesting things<br />
are those in physics, like to understand<br />
things in the very fundamental<br />
level.<br />
What happens in the level of elementary<br />
parts, how they interact,<br />
and this gives life to the things we<br />
see. This is basically what we are doing<br />
in condensed matter physics.<br />
Put a lot of small things together, let<br />
them interact and out comes all the<br />
properties of materials around us in<br />
all many different colors and flavors,<br />
and I like to make this connection<br />
from very simple fundamental walls<br />
to all this diversity of things that we<br />
see.<br />
<strong>IIP</strong> NEWS - How was your first contact<br />
with the <strong>IIP</strong>?<br />
PROF. RODRIGO PEREIRA - That<br />
was shortly after I moved back to<br />
Brazil. I was in São Carlos and together<br />
with Professors Francisco Alcaraz<br />
and José Hoyos, we said that we<br />
wanted to organize a winter school<br />
in statistical physics. At first we<br />
thought about doing it in São Carlos,<br />
but then we learned about the<br />
<strong>IIP</strong> and how they were organizing so<br />
many events, so I liked the idea. So,<br />
the first time I came here was as an<br />
organizer, and for me it was an interesting<br />
experience as well, because I<br />
was organizing a school that I had<br />
participated before as a student, in a<br />
previous edition in São Carlos.<br />
<strong>IIP</strong> NEWS - What are you working on<br />
right now?<br />
PROF. RODRIGO PEREIRA - These<br />
days I’ve been mainly thinking about<br />
cold atoms systems. So one of the<br />
things I do is something call quantum<br />
impurity models. What happens<br />
when you have some kind of<br />
system that can be even non interactive,<br />
but you add a different atom<br />
or something that is gonna move in<br />
the system and interact with everything<br />
else, and ask about how that<br />
changes the properties of the system<br />
locally or of this object that is<br />
moving around? So at the moment<br />
I am working on a problem of impurity<br />
in a two dimensional fermy gas,<br />
that has some special kind of interaction<br />
that completely chances all<br />
the properties of the particle that<br />
is moving in that system, and that<br />
uses field theory matters, because<br />
it can show that this kind of interaction<br />
is renormalizable and it moves<br />
to different low energy properties<br />
depending on the fractures on the<br />
model, and I try to understand what<br />
the different possibilities are.<br />
<strong>IIP</strong> NEWS - What advice would you<br />
give to the students that are joining<br />
the physics course today and want<br />
to join the research career?<br />
PROF. RODRIGO PEREIRA - I would<br />
say go for it. It is worth it. From the<br />
beginning it looks very hard, because<br />
you have to work very hard<br />
and study a lot, and the prospect<br />
of becoming a professor seems so<br />
far away. For me it was like that.<br />
But I really believe that if you work<br />
hard enough the opportunities will<br />
come. You have a lot of chances to<br />
interact with people with similar<br />
interests, meet people from many<br />
different countries, so it’s a very nice<br />
profession and I would recommend<br />
it to everybody who is really excited<br />
about doing research.

<strong>IIP</strong>-UFRN hosts special event to celebrate the<br />
Physicist Day in Brazil<br />
<strong>IIP</strong> <strong>News</strong> - Year I, number 01<br />
The <strong>IIP</strong> and the Department of Theoretical and<br />
Experimental Physics (DFTE-UFRN) held a joint event<br />
last May 19, to celebrate the Brazilian Physicist Day.<br />
During this special activity, the <strong>IIP</strong> auditorium was<br />
crowded with students, Professors and researchers<br />
from the local scientific community, who participated<br />
in a series of presentations of the university’s research<br />
groups in physics.<br />
Many grad-students were present and could learn<br />
more about the research fields of the <strong>IIP</strong> and DFTE, as<br />
well as know more about the researchers and visiting<br />
researchers developing their work at the university.<br />
“I liked a lot. It was very interesting to know about the<br />
subjects that the researchers from DFTE and the <strong>IIP</strong> are<br />
studying”, said Herman Bueno, a 7º semester physics<br />
grad student from UFRN.<br />
According to <strong>IIP</strong> Professor Dmitry Melnikov, this was<br />
also an opportunity for physicists from <strong>IIP</strong> and the DFTE<br />
to learn more about the research in progress in the<br />
many groups of both centers.<br />
“I was very happy to see so many participants in this<br />
event, specially the grad-students, who could learn<br />
more about the research lines being studied at the<br />
University. It was very nice to me too, since I got to<br />
know more about my colleagues research here at the<br />
University”, said Professor Melnikov.<br />
More than 100 members of the local scientific<br />
community participated in the 13 lectures offered<br />
during the event, which the organizers hope to<br />
transform into an annual activity.<br />

“Kerr Scattering coefficient via isomonodromy”<br />
Work developed by researchers Fabio Novaes (<strong>IIP</strong>-UFRN) e Bruno Carneiro Cunha (UFPE)<br />
In a paper recently published in the Journal of High<br />
Energy Physics, <strong>IIP</strong> researcher Dr. Fabio Novaes<br />
and Prof. Bruno Carneiro da Cunha from UFPE,<br />
presented a new method to calculate scattering<br />
coefficients of scalar waves propagating around<br />
arotating black hole, the so-called Kerr black hole.<br />
Scalar wave scattering is usually studied through<br />
the Klein-Gordon equation, in a curved background,<br />
to model the behavior of waves when<br />
launched into a black hole. This method analyzes<br />
the waves reflected and transmitted during this<br />
process. The essential quantity calculated is the<br />
scattering coefficient.<br />
Novaes and Carneiro Cunha proposed a way to<br />
express scattering data using the monodromy of<br />
solutions of Klein-Gordon equation, inspired by<br />
previous work of Castro et al. in Class.Quant.Grav.<br />
30 (2013) 165005. The crucial quantity in the expression<br />
is the composite monodromy, which can<br />
be calculated via their novel application of the isomonodromy<br />
deformation of these equations. This<br />
work explores the relationship of isomonodromic<br />
deformations and Painlevé VI τ-function, recently<br />
developed in detail by O. Gamayun, N. Iorgov and<br />
O. Lisovyy in JHEP 1210 (2012) 038 and first discovered<br />
by Japanese mathematicians Jimbo, Miwa<br />
and Ueno in the 1980’s.<br />
Dr. Fábio Novaes now works in new applications<br />
of the method in gravitational waves and in the<br />
relationship between Gravity and Conformal Field<br />
Theory (CFT).
