Interaction quenches in the two-dimensional fermionic Hubbard model
Simone A. Hamerla, Götz S. Uhrig
The generic non-equilibrium evolution of a strongly interacting fermionic system is studied. For strong quenches, a collective collapse-and-revival phenomenon is found extending ov…
Dynamical Transition in Interaction Quenches of the One-Dimensional Hubbard Model
Simone A. Hamerla, Götz S. Uhrig
We show that the non-equilibrium time-evolution after interaction quenches in the one dimensional, integrable Hubbard model exhibits a dynamical transition in the half-filled case.…
One-dimensional fermionic systems after interaction quenches and their description by bosonic field theories
Simone A. Hamerla, Götz S. Uhrig
We show that the dynamics of quenches in one dimension far off equilibrium can be described by power laws, but with exponents differing from the fully renormalized ones at lowest e…
Derivation of the t-J model for finite doping
Simone A. Hamerla, Sebastian Duffe, Götz S. Uhrig
Mapping complex problems to simpler effective models is a key tool in theoretical physics. One important example in the realm of strongly correlated fermionic systems is the mappin…
