On Exponentially Long Prethermalization Timescales in Isolated Quantum Systems

open access: yesStudies in Applied Mathematics, Volume 157, Issue 3, September 2026.
ABSTRACT We study prethermalization in time‐independent quantum many‐body systems on a d$d$‐dimensional lattice with an extensive local Hamiltonian H=N+εP$H=N+\varepsilon P$, in the regime where ε≪1$\varepsilon \ll 1$. We prove that the prethermal timescale is exponential in ε0/ε$\varepsilon _0/\varepsilon$, where ε0$\varepsilon _0$ is an explicit ...

openMMF/Multimode-Floquet: Version ready for public distribution

open access: yes, 2020
The openMMF library implements the Multimode Floquet method to evaluate the time-evolution operator of harmonically driven quantum systems. This first release includes a number of tested examples (examples/FORTRAN & examples/CPP).

An Optically Transparent Metamaterial Window Based on Metal Meshes With Integrated Absorption and Transmission

open access: yesNanophotonics, Volume 15, Issue 16, 26 August 2026.
We demonstrate an optically transparent metallic‐mesh electromagnetic window that integrates radar‐frequency absorption, millimeter‐wave transmission, and visible‐light transparency within a single passive architecture, providing a new approach for multifunctional electromagnetic control.

Floquet-Bloch Theory for Semiconductor Bragg Structure [PDF]

open access: yes, 2020
The problem of Floquet-Bloch waves propagation in a semiconductor magnetophotonic crystal with a transverse magnetic field was solved. The fundamental solutions of the Hill equation in layers that based on the Floquet theory were obtained in an ...

Francese e portoghese in Africa: aspetti contrastivi

open access: yes, 2021
Fra tutte le lingue romanze, il francese e il portoghese sono quelle che più hanno influenzato da un punto di vista politico e sociale la storia linguistica e culturale del continente africano e che presentano la maggiore diffusione geografica.

Ultra‐Broadband Optical Characterization of TiO2 Nanotube Arrays Revealing Annealing‐Tunable THz Absorption

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
Lithography‐free spaced TiO2 NT arrays unlock tunable broadband absorption from THz to UV. By harnessing annealing‐driven phase transitions, strong phonon–polariton resonances emerge in the 1.4–3.6 THz range, whereas high absorptance persists beyond 10 THz.

Wave propagation in periodic fluid-solid layered media

open access: yesГеофизический журнал, 2016
Dispersion equation is derived for the Floquet waves in a horizontal periodically layered fluid-solid medium. It is shown that the dispersion equation consists of four factors.

Optical Responses From Zero Optical‐Path‐Length Object

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
This work address a fundamental question—what is the ultimately minimal embodiment of optical objects that produce useful optical effects? In fact, such an object does not require nonzero physical and optical‐path‐length volume as opposed to the conventional perception.

Symmetry-protected topological phases: From Floquet theory to machine learning [PDF]

open access: yes, 2020
It is by now a well known fact that boundary states in conventional time-independent topological insulators are protected against perturbations that preserve relevant symmetries. In the first part of this thesis, accompanying Papers A - C, we study how
