Dynamically assisted tunneling in the impulse regime
Christian Kohlfürst, Friedemann Queisser, Ralf Schützhold
We study the enhancement of tunneling through a potential barrier by a time-dependent electric field with special emphasis on pulse-shaped vector potentials such as $A_x(t)=…
Boltzmann relaxation dynamics of strongly interacting spinless fermions on a lattice
Friedemann Queisser, Sebastian Schreiber, Peter Kratzer +1
Motivated by the recent interest in non-equilibrium phenomena in quantum many-body systems, we study strongly interacting fermions on a lattice by deriving and numerically solving…
Boltzmann relaxation dynamics in the strongly interacting Fermi-Hubbard model
Friedemann Queisser, Ralf Schützhold
Via the hierarchy of correlations, we study the Mott insulator phase of the Fermi-Hubbard model in the limit of strong interactions and derive a quantum Boltzmann equation describi…
