We investigate the nonequilibrium spin polarization due to a temperature gradient in antiferromagnetic insulators, which is the magnonic analog of the inverse spin-galvanic effect of electrons. We derive a linear-response theory of a temperature-gradient-induced spin polarization for collinear and noncollinear antiferromagnets, which comprises both extrinsic and intrinsic contributions. We apply our theory to several noncentrosymmetric antiferromagnetic insulators, i.e., to a one-dimensional…

Spin superfluidity in noncollinear antiferromagnets

We explore the spin superfluid transport in exchange interaction-dominated three-sublattice antiferromagnets. The system in the long-wavelength regime is described by an $\mathrm{S}\mathrm{O}(3)$

Magnon thermal Edelstein effect detected by inverse spin Hall effect

In an easy-plane antiferromagnet with the Dzyaloshinskii-Moriya interaction (DMI), magnons are subject to an effective spin-momentum locking. An in-plane temperature gradient can generate interfacial

Topological Hybrids of Magnons and Magnon Bound Pairs

We consider quantum condensed matter systems without particle-number conservation. Since the particle number is not a good quantum number, states belonging to di ff erent particle-number sectors can

Pseudo-Edelstein effect in disordered silicene

These findings show that ‘pseudo-Edelstein’ response function is weakened by the intrinsic Rashba spin–orbit interaction which originally arises from buckling in silicene.

Antisymmetric thermopolarization by electric toroidicity

We investigate electric polarizations emergent perpendicular to an applied thermal gradient in insulating systems. The thermally-induced electric polarization, known as thermopolarization, has been

It is demonstrated that magnets exhibiting a magnonic orbital moment are omnipresent and proposed transport experiments for probing it are proposed.

Anisotropic Superexchange Interaction and Weak Ferromagnetism

A theory of anisotropic superexchange interaction is developed by extending the Anderson theory of superexchange to include spin-orbit coupling. The antisymmetric spin coupling suggested by

We theoretically study magnetic and topological properties of antiferromagnetic kagome spin systems in the presence of both in- and out-of-plane Dzyaloshinskii-Moriya interactions. In materials such

Competing phases and topological excitations of spin-1 pyrochlore antiferromagnets

Most works on pyrochlore magnets deal with the interacting spin-1/2 local moments. We here study the spin-one local moments on the pyrochlore lattice, and propose a generic interacting spin model on

Orbitally dominated Rashba-Edelstein effect in noncentrosymmetric antiferromagnets

A generalized Rashba-Edelstein effect is reported, which generates not only spin polarization but also orbital polarization, which is found to be far from being negligible.

By revealing an underlying relation between the Dzyaloshinskii-Moriya interaction (DMI) and the scalar spin chirality, we develop the theory of magnon thermal Hall effects in antiferromagnetic

Intrinsic spin Nernst effect of magnons in a noncollinear antiferromagnet

We investigate the intrinsic magnon spin current in a noncollinear antiferromagnetic insulator. We introduce a definition of the magnon spin current in a noncollinear antiferromagnet and find that it
