Quench dynamics in topologically non-trivial quantum many-body systems
Sarika Sasidharan Nair, Giedrius Žlabys, Wen-Bin He +2
We investigate the nonequilibrium dynamics of a groundstate fermionic many body gas subjected to a quench between parameter regimes of a topologically nontrivial Hamiltonian. By fo…

Flow-equation approach to quantum systems driven by an amplitude-modulated time-periodic force
Viktor Novičenko, Giedrius Žlabys, Egidijus Anisimovas
We apply the method of flow equations to describe quantum systems subject to a time-periodic drive with a time-dependent envelope. The driven Hamiltonian is expressed in terms of i…
