Mode attraction in Floquet systems with memory: application to magnonics
Igor Proskurin, Jephthah Iyaro, Robert L. Stamps
Level attraction is a type of mode hybridization in open systems where instead of forming a hybridization gap, the energy spectrum of two modes coalesce in a region bounded by exce…
Collective dynamics of domain walls: an antiferromagnetic spin texture in an optical cavity
Jephthah Iyaro, Igor Proskurin, Robert L. Stamps
Spin canting and complex spin textures in antiferromagnetic materials can often be described in terms of Dzyaloshinskii-Moriya interactions (DMI). Values for DMI parameters are not…
Level attraction and exceptional points in a resonant spin-orbit torque system
Igor Proskurin, Robert L. Stamps
Level attraction can appear in driven systems where instead of repulsion two modes coalesce in a region separated by two exceptional points. This behavior was proposed for optomech…
Symmetry Approach to Chiral Optomagnonics in Antiferromagnetic Insulators
Igor Proskurin, Robert L. Stamps
We discuss several aspects of chiral optomagnonics in antiferromagnetic insulators by considering common symmetries between the electromagnetic field and spin excitations. This app…
Microscopic origin of level attraction for a coupled magnon-photon system in a microwave cavity
Igor Proskurin, Rair Macêdo, Robert L. Stamps
We discuss various microscopic mechanisms for level attraction in a hybridized magnon-photon system of a ferromagnet in a microwave cavity. The discussion is based upon the electro…
Selection Rules for Optical Vortex Absorption by Landau-quantized Electrons
Hirohisa T. Takahashi, Igor Proskurin, Jun-ichiro Kishine
An optical vortex beam carries orbital angular momentum in addition to spin angular momentum . We demonstrate that a Landau-quantized two dimensional electron system abso…
Theory of standing spin waves in finite-size chiral spin soliton lattice
J. Kishine, Vl. E. Sinitsyn, I. G. Bostrem +4
We present a theory of standing spin wave (SSW) in a monoaxial chiral helimagnet. Motivated by experimental findings on the magnetic field-dependence of the resonance frequency in…
Cavity Optomechanics of Topological Spin Textures in Magnetic Insulators
Igor Proskurin, Alexander S. Ovchinnikov, Jun-ichiro Kishine +1
Collective dynamics of topological magnetic textures can be thought of as a massive particle moving in a magnetic pinning potential. We demonstrate that inside a cavity resonator t…
Excitation of magnon spin photocurrents in antiferromagnetic insulators
Igor Proskurin, Alexander S. Ovchinnikov, Jun-ichiro Kishine +1
In the circular photogalvanic effect, circularly polarized light can produce a direct electron photocurrent in metals and the direction of the current depends on the polarization.…
Theory of magnetoelastic resonance in a mono-axial chiral helimagnet
A. A. Tereshchenko, A. S. Ovchinnikov, I. Proskurin +2
We study magnetoelastic resonance phenomena in a mono-axial chiral helimagnet belonging to hexagonal crystal class. By computing the spectrum of coupled elastic wave and spin wave,…
Spin-wave chirality and its manifestations in antiferromagnets
Igor Proskurin, Robert L. Stamps, Alexander S. Ovchinnikov +1
As first demonstrated by Tang and Cohen in chiral optics, the asymmetry in the rate of electromagnetic energy absorption between left and right enantiomers is determined by an opti…
Functional renormalization-group approach to the Pokrovsky-Talapov model via modified massive Thirring fermion model
P. A. Nosov, Jun-ichiro Kishine, A. S. Ovchinnikov +1
A possibility of the topological Kosterlitz-Thouless~(KT) transition in the Pokrovsky-Talapov~(PT) model is investigated by using the functional renormalization-group (RG) approach…
