Floquet Spin Splitting and Spin Generation in Antiferromagnets
Bo Li, Ding-Fu Shao, Alexey A. Kovalev
In antiferromagnetic spintronics, accessing the spin degree of freedom is essential for generating spin currents and manipulating magnetic order, which generally requires lifting s…
Nonreciprocal superfluidlike topological spin transport
Alexey A. Kovalev, Bo Li, Edward Schwartz
We study superfluidlike spin transport facilitated by thermal diffusion of magnetic domain walls, where the positive and negative chiralities of domain walls act as opposite topolo…
Superfluid Spin Transistor
Edward Schwartz, Bo Li, Alexey A. Kovalev
We propose to use the Hall response of topological defects, such as merons and antimerons, to spin currents in 2D magnetic insulator with in-plane anisotropy for identification of…
Spin superfluidity in noncollinear antiferromagnets
Bo Li, Alexey A. Kovalev
We explore the spin superfluid transport in exchange interaction dominated three-sublattice antiferromagnets. The system in the long-wavelength regime is described by an in…
Magnon Landau Levels and Spin Responses in Antiferromagnets
Bo Li, Alexey A. Kovalev
We study gauge fields produced by gradients of the Dzyaloshinskii-Moriya interaction and propose a model of AFM topological insulator of magnons. In the long wavelength limit, the…
Magnonic Analogue of Edelstein Effect in Antiferromagnetic Insulators
Bo Li, Alexander Mook, Aldo Raeliarijaona +1
We investigate the nonequilibrium spin polarization due to a temperature gradient in antiferromagnetic insulators, which is the magnonic analogue of the inverse spin-galvanic effec…
Intrinsic spin Nernst effect of magnons in a noncollinear antiferromagnet
Bo Li, Shane Sandhoefner, Alexey A. Kovalev
We investigate the intrinsic magnon spin current in a noncollinear antiferromagnetic insulator. We introduce a definition of the magnon spin current in a noncollinear antiferromagn…
Chiral topological insulator of magnons
Bo Li, Alexey A. Kovalev
We propose a magnon realization of 3D topological insulator in the AIII (chiral symmetry) topological class. The topological magnon gap opens due to the presence of Dzyaloshinskii-…
Pumping of magnons in a Dzyaloshinskii-Moriya ferromagnet
Alexey A. Kovalev, Vladimir A. Zyuzin, Bo Li
We formulate a microscopic linear response theory of nonequilibrium magnonic torques and magnon pumping applicable to multiple-magnonic-band uniform ferromagnets with Dzyaloshinski…
