<strong>The</strong> Schrödinger equation<br />
We consider different families of Geometric Integrators for solving the SE<br />
<strong>The</strong> solution of the discretised autonomous equation is given by<br />
where c = (c 1,…, c N) T C N and H = T + V R N×N Hermitian matrix.<br />
Fourier methods are frequently used<br />
is the fast Fourier transform (FFT)
