DOI: 10.1088/1367-2630/accb05
Abstract: Floquet engineering consists in the modification of physical systems by the application of periodic time-dependent perturbations. The search for the shape of the periodic perturbation that best modifies the properties of a system in order… read more here.

DOI: 10.1103/physreva.107.043309
Abstract: Using two-frequency driving in two dimensions opens up new possibilites for Floquet engineering, which range from controlling specific symmetries to tuning the properties of resonant gaps. In this work, we study two-band lattice models subject… read more here.

DOI: 10.1103/physrevb.105.l020301
Abstract: We propose a ‘Floquet engineering’ formalism to systematically design a periodic driving protocol in order to stroboscopically realize the desired system starting from a given static Hamiltonian. The formalism is applicable to interacting and non-interacting… read more here.

DOI: 10.1103/physrevb.95.045102
Abstract: The realization of synthetic gauge fields has attracted a lot of attention recently in relation to periodically driven systems and the Floquet theory. In ultracold atom systems in optical lattices and photonic networks, this allows… read more here.

DOI: 10.1103/physrevlett.124.190601
Abstract: We show how second-order Floquet engineering can be employed to realize systems in which many-body localization coexists with topological properties in a driven system. This allows one to implement and dynamically control a symmetry protected… read more here.

Abstract: We study Floquet engineering of the tunnel coupling between a pair of one-dimensional bosonic quasicondensates in a tilted double-well potential. By modulating the energy difference between the two wells, we reestablish tunnel coupling and precisely… read more here.

DOI: 10.1134/s1063782618040176
Abstract: It is demonstrated theoretically that the interaction of gapped 2D materials (gapped graphene and transition metal dichalchogenide monolayers) with a strong high-frequency electromagnetic field (dressing field) crucially changes the band structure of the materials. As… read more here.
