Dynamics of Hubbard nano-clusters following strong excitation
M. Bonitz, S. Hermanns, K. Balzer
The Hubbard model is a prototype for strongly correlated electrons in condensed matter, for molecules and fermions or bosons in optical lattices. While the equilibrium properties o…
The generalized Kadanoff-Baym ansatz. Computing nonlinear response properties of finite systems
K. Balzer, S. Hermanns, M. Bonitz
For a minimal Hubbard-type system at different interaction strengths U, we investigate the density-response for an excitation beyond the linear regime using the generalized Kadanof…
Nonequilibrium Green's function approach to the pair distribution function of quantum many-body systems out of equilibrium
M. Bonitz, S. Hermanns, K. Kobusch +1
The pair distribution function (PDF) is a key quantity for the analysis of correlation effects of a quantum system both in equilibrium and far from equilibrium. We derive an expres…
Phase diagram of bilayer electron-hole plasmas
J. Schleede, A. Filinov, M. Bonitz +1
We investigate exciton bound-state formation and crystallization effects in two-dimensional electron-hole bilayers. Performing unbiased path integral Monte Carlo simulations all qu…
Effective interaction potential and superfluid-solid transition of spatially indirect excitons
A. Filinov, P. Ludwig, M. Bonitz +1
Using an adiabatic approximation we derive an effective interaction potentially for spatially indirect excitons. Using this potential and path integral Monte Carlo simulations we s…
Hole crystallization in semiconductors
M. Bonitz, V. S. Filinov, V. E. Fortov +2
When electrons in a solid are excited to a higher energy band they leave behind a vacancy (hole) in the original band which behaves like a positively charged particle. Here we pred…
