Floquet-engineered light-cone spreading of correlations in a driven quantum chain
Mona H. Kalthoff, Dante M. Kennes, Michael A. Sentef
We investigate the light-cone-like spread of electronic correlations in a laser-driven quantum chain. Using the time-dependent density matrix renormalization group, we show that hi…

Positivity of the spectral densities of retarded Floquet Green functions
Götz S. Uhrig, Mona H. Kalthoff, James K. Freericks
Periodically driven nonequilibrium many-body systems are interesting because they have a quasi-energy spectra, which can be tailored by controlling the external driving fields. We…

Emergence of Floquet Behavior for Lattice Fermions Driven by Light Pulses
Mona H. Kalthoff, Götz S. Uhrig, J. K. Freericks
As many-body Floquet theory becomes more popular, it is important to find ways to connect theory with experiment. Theoretical calculations can have a periodic driving field that is…
