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

open access: yesGlobal 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.

Application of multisection recursive convolution in 3D FETD-FABC simulations [PDF]

open access: yes, 2008
The multisection recursive convolution (MS-RC) methodology is successfully applied to the finite element time domain floquet absorbing boundary condition modeling of doubly periodic structures.

Floquet dynamics in light-driven solids

open access: yesPhysical Review Research, 2020
We demonstrate how the properties of light-induced electronic Floquet states in solids impact natural physical observables, such as transport properties, by capturing the environmental influence on the electrons. We include the environment as dissipative

Projective spacetime symmetry of spacetime crystals

open access: yesCommunications Physics, 2023
Wigner’s seminal work on the Poincaré group revealed one of the fundamental principles of quantum theory: symmetry groups are projectively represented. The condensed-matter counterparts of the Poincaré group could be the spacetime groups of periodically ...

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

open access: yesChaos: 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.

A Floquet theory‐based fast time‐domain stability analysis for N‐parallel inverters system

open access: yesIET Power Electronics, 2022
Based on Floquet theory, a simple and fast time‐domain stability analysis method for an N‐parallel inverters system is proposed. Furthermore, a general time‐domain model of the N‐parallel inverters system in grid‐connected mode and in island mode are ...

Floquet–Mie Theory for Time‐Varying Dispersive Spheres

open access: yesLaser & Photonics Reviews, 2022
Exploring the interaction of light with time‐varying media is an intellectual challenge that, in addition to fundamental aspects, provides a pathway to multiple promising applications.

Modal Analysis of Light Propagation, Polarization and Diffraction by Cholesteric Liquid Crystal Layers

open access: yesAdvanced Functional Materials, EarlyView.
The analysis of optical eigenmodes in chiral liquid crystal with perpendicular or tilted helical axis, and their correspondence with the external medium, leads to an intuitive understanding of the angle and wavelength dependency of transmissive and reflective diffraction.

Simultaneous symmetry breaking in spontaneous Floquet states: temporal Floquet-Nambu-Goldstone modes, Floquet thermodynamics, and the time operator [PDF]

open access: yesQuantum
We study simultaneous symmetry breaking in spontaneous Floquet states, focusing on the specific case of an atomic condensate. We first describe the quantization of the Nambu-Goldstone (NG) modes for a stationary state simultaneously breaking several ...
