The Peschel research group at the IFTO provides an ultramodern, highly parallelized computer infrastructure in order to work on solutions in the realm of nanophysics and quantum chemistry. Incorporated at the Abbe Center of Photonics and the Michael Stifel Center, the new infrastructure enables various research groups at the Friedrich Schiller University to use the latest simulation tools and methods in their inquiries about light-matter interactions.

The picture shows is a simulation of the transient process of an optically pumped semiconductor nanowire-laser made of CdS:
a)    Configuration
b)    Field distribution
c)    MISSING
d)    Dynamics of the field intensity (blue) and charge carrier density (green) at the core of the nanowire (excitation pulse is set at t=0)
e)   Spectral dynamics
f)    Dynamics of the inversion in the field of quasi-momentum

Another example for the applicability of the new computer infrastructure are the structures of (R,R) and (R,S)-1,2-dimethyloxiran and their respective photoelectron angular distribution according their ionization with left- or right-circular ly polarized laser pulses (LCP, respectively RCP). 

The project is co-financed by the state of Thuringia and the European Union with resources from the European Regional Development Fund (ERDF).
