Unified light-matter Floquet theory and its application to quantum communication [PDF]
Physical Review Research, 2022 Periodically driven quantum systems can exhibit a plethora of intriguing nonequilibrium phenomena that can be analyzed using Floquet theory. Naturally, Floquet theory is employed to describe the dynamics of atoms interacting with intense laser fields ...

Floquet-Landau-Zener interferometry: Usefulness of the Floquet theory in pulse-laser-driven systems [PDF]
Physical Review Research, 2022 We develop the Landau-Zener transfer matrix theory for the instantaneous Floquet states (IFSs) for quantum systems driven by a strong pulse laser. Applying this theory to the pulse excitation probability in two-level quantum systems, we show unexpectedly

Integrable Floquet systems related to logarithmic conformal field theory [PDF]
SciPost Physics, 2023 We study an integrable Floquet quantum system related to lattice statistical systems in the universality class of dense polymers. These systems are described by a particular non-unitary representation of the Temperley-Lieb algebra.

Physical Review XWe derive Floquet theory from quantum geometry. We identify quasienergy folding as a consequence of a broken gauge group of the adiabatic gauge potential U(1)↦Z.

Floquet engineering the band structure of materials with optimal control theory [PDF]
Physical Review Research, 2022 We demonstrate that the electronic structure of a material can be deformed into Floquet pseudobands with arbitrarily tailored shapes. We achieve this goal with a combination of quantum optimal control theory and Floquet engineering.

Floquet stroboscopic divisibility in non-Markovian dynamics
New Journal of Physics, 2018 We provide a general description of a time-local master equation for a system coupled to a non-Markovian reservoir based on Floquet theory. This allows us to have a divisible dynamical map at discrete times, which we refer to as Floquet stroboscopic ...

Floquet engineering with quantum optimal control theory
New Journal of Physics, 2023 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 to achieve some

Band Tuning of Phosphorene Semiconductor via Floquet Theory
Journal of Electronic Materials, 2019 Graphene and phosphorene are monolayer of graphite and phosphorous, respectively. Graphene is completely relativistic (Dirac) fermionic system, but phosphorene is pseudorelativistic fermionic system. In phosphorene, electronic spectrum of phosphorene has
