Time-Dependent Mean Field Theory for Quench Dynamics in Correlated Electron Systems
Time-Dependent Mean Field Theory for Quench Dynamics in Correlated Electron Systems
A simple and very flexible variational approach to the out-of-equilibrium quantum dynamics in strongly correlated electron systems is introduced through a time-dependent Gutzwiller wavefunction. As an application, we study the simple case of a sudden change of the interaction in the fermionic Hubbard model and find at the mean field …
