Comment on "Floquet Fractional Chern Insulators"
Luca D'Alessio
In a recent paper [Phys. Rev. Lett. 112 156801 (2014)], Grushin et al. studied a Fermi-Hubbard-model for spinful electrons on a honeycomb lattice coupled to an external polarized e…
Dynamical preparation of Floquet Chern insulators
Luca D'Alessio, Marcos Rigol
Realizing topological insulators is of great current interest because of their remarkable properties and possible future applications. There are recent proposals, based on Floquet…
Universal High-Frequency Behavior of Periodically Driven Systems: from Dynamical Stabilization to Floquet Engineering
Marin Bukov, Luca D'Alessio, Anatoli Polkovnikov
We give a general overview of the high-frequency regime in periodically driven systems and identify three distinct classes of driving protocols in which the infinite-frequency Floq…
Negative mass corrections in a dissipative stochastic environment
Luca D'Alessio, Yariv Kafri, Anatoli Polkovnikov
We study the dynamics of a macroscopic object interacting with a dissipative stochastic environment using an adiabatic perturbation theory. The perturbation theory reproduces known…
Long-time behavior of periodically driven isolated interacting lattice systems
Luca D'Alessio, Marcos Rigol
We study the dynamics of isolated interacting spin chains that are periodically driven by sudden quenches. Using full exact diagonalization of finite chains, we show that these sys…
