Effective Theory of Floquet Topological Transitions [PDF]

Physical Review Letters, 2014
We develop a theory of topological transitions in a Floquet topological insulator, using graphene irradiated by circularly polarized light as a concrete realization. We demonstrate that a hallmark signature of such transitions in a static system, i.e.

The Floquet–Magnus and Fer Expansions: Application to Control the Spin Dynamics During the Phase Modulated Lee–Goldburg Radiation in Solid-State NMR

Reports in Advances of Physical Sciences, 2023
Floquet–Magnus and Fer expansion (FE) schemes are used in nuclear magnetic resonance (NMR) for the calculation of effective Hamiltonians and propagators.

Robust orbital stabilization: A Floquet theory–based approach [PDF]

International Journal of Robust and Nonlinear Control, 2021
AbstractThe design of robust orbitally stabilizing feedback is considered. From a known orbitally stabilizing controller for a nominal, disturbance‐free system, a robustifying feedback extension is designed utilizing the sliding‐mode control (SMC) methodology. The main contribution of the article is to provide a constructive procedure for designing the

Application of Floquet theory to dynamical systems with memory [PDF]

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2020
We extend the recently developed generalized Floquet theory [Phys. Rev. Lett. 110, 170602 (2013)] to systems with infinite memory, i.e., a dependence on the whole previous history. In particular, we show that a lower asymptotic bound exists for the Floquet exponents associated to such cases.

Topological chiral modes in random scattering networks

SciPost Physics, 2020
Using elementary graph theory, we show the existence of interface chiral modes in random oriented scattering networks and discuss their topological nature. For particular regular networks (e.g.

Floquet engineering the band structure of materials with optimal control theory

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.

Visualization of the 3D stability zone of a quadrupole mass filter in the static longitudinal magnetic field

St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2022
A new visualization method has been put forward to show the three-dimensional stability zones of a quadrupole mass filter placed in the constant uniform magnetic field directed along the quadrupole axis.

Impact of seasonal cycles on host-pathogen dynamics and disease mitigation for Batrachochytrium salamandrivorans

Global Ecology and Conservation, 2019
Seasonal cycles have a demonstrated effect on the dynamics of human and animal diseases. However, their quantitative implications for disease mitigation in wildlife are less well studied.
