Short description of company<br />

Research activities of the Condensed Matter Theory Group at the Institute of Physics (Wroclaw University of<br />

Technology) address a wide spectrum of topics in condensed matter theory. In the area of semiconductors<br />

physics properties of the strongly correlated two-dimensional electron liquid (Quantum Hall Effect) and properties<br />

of semiconductor quantum dots are studied. The theory of superconductivity in high-Tc systems is also<br />

developed. Problems of the local structure of liquids are also studied as are the issues of information storage and<br />

processing in polymer and liquid crystal systems. In our group the ab inito calculations of molecular and solid<br />

state structures are performed. Within the scope of research are also the recent proposals for solid state<br />

implementations of quantum information processing. In particular, decoherence in such systems are studied.<br />

Studies of interactions between nano-sized objects and surrounding enviroment have been recently intensively<br />

developed in the context of nano-modified materials.<br />

Research in such a wide spectrum is possible due to cooperation of senior institute staff with a large group of<br />

PhD and graduate students. International cooperation as well as active participation in national and international<br />

research projects plays an important role in the dynamics of our research activities.<br />

Research activites are complemented by a wide educational offer for university students, including specialized<br />

lectures in methods of solid state theory (e.g. Green functions, group theory), quantum information, quantum<br />

cryptography and quantum optics.<br />

1. Profile: Expertise: Physics of nano-scale objects embedded in a bulk environment<br />

DESCRIPTION:<br />

Previous studies on quantum dot systems conducted at Wroclaw University of Technology pointed out that the<br />

mutual interaction between nano-sized objects and surrounding environment is crucial for feasibility of various<br />

practical implementations. Moreover, it seems that the overwhelming trend for miniaturization will be slowed<br />

down or even stopped at some point due to inherently different physical laws that govern systems on the<br />

nanometer scale. It is worth to underline that the majority of phenomena in nano-scale objects (e.g. quantum<br />

dots), do not have their counterparts in atomic and bulk condensed matter physics. This especially affects the<br />

object-environment interaction, which is highly sensitive to unavoidable excitations such as phonons or magnons,
