Gentle Floquet control of orbital Hall effect and orbital inverse Faraday effect
Pei-Han Lin, Roderich Moessner, Egor I. Kiselev
Floquet engineering controls material responses via a time-periodic electromagnetic drive. An important task in practice is to reduce the driving strengths required to implement Fl…
Dynamical breaking of inversion symmetry, strong second harmonic generation, and ferroelectricity with nonlinear phonons
Egor I. Kiselev
We show how crystalline inversion symmetry can be dynamically broken by optical phonons with generic, hardening Kerr-like non-linearities. The symmetry-broken state is reached thro…
Exciting terahertz magnons with amplitude modulated light: spin pumping, squeezed states, symmetry breaking and pattern formation
Egor I. Kiselev, Jonas F. Karcher, Mark S. Rudner +2
We show how amplitude modulated, coherent high-frequency drives can be used to access otherwise difficult to reach collective resonances and off-resonantly induce parametric instab…
Orbital Hall Effect and Angular Momentum Dynamics in Confined Geometries
Egor I. Kiselev, Benoît Douçot, Roderich Moessner
We present an analysis of the orbital Hall effect (OHE) in a strip geometry and derive a formula for the orbital angular momentum (OAM) accumulation at the edges. The result is exp…
Symmetry Breaking and Spatiotemporal Pattern Formation in Photonic Time Crystals
Egor I. Kiselev, Yiming Pan
In this work, we explore the dynamics of time varying photonic media with an optical Kerr nonlinearity and an associated phase transition. The interplay between a periodically modu…
Light controlled THz plasmonic time varying media: momentum gaps, entangled plasmon pairs, and pulse induced time reversal
Egor I. Kiselev, Yiming Pan, Netanel H. Lindner
This letter establishes a Floquet engineering framework in which coherent high frequency light with a time dependent amplitude can be used to parametrically excite and amplify THz…
