A class of antiferromagnets with spin-polarized electron bands, yet zero net magnetization,
called altermagnets, is attracting increasing attention due to their potential use in spintronics …

At the interface between a ferromagnetic insulator and a superconductor there is a coupling
between the spins of the two materials. We show that when a supercurrent carried by triplet …

Spin pumping from a ferromagnetic insulator into a high-T c superconductor with ad-wave
superconducting order parameter has recently been experimentally observed. Such …

We study a dynamical spin response of surface Majorana modes in a topological
superconductor–magnet hybrid under microwave irradiation. We find a method to toggle …

We study spin pumping into an anisotropic Dirac electron system induced by microwave
irradiation to an adjacent ferromagnetic insulator theoretically. We formulate the Gilbert …

We develop a microscopic theory of tunneling spin transport at the magnetic interface
between a ferromagnetic insulator (FI) and a ferromagnetic superconductor (FSC) driven by …

We theoretically study the generation of spin current due to a surface acoustic wave (SAW)
in a superconductor. We model an s-wave superconductor as the mean-field Hamiltonian …

We theoretically investigate spin pumping into a quantum easy-plane ferromagnetic spin
chain system. This quantum spin chain is effectively described by the Tomonaga-Luttinger …

We explore the theoretical possibility of P 0 3 neutron superfluid in dilute spin-polarized
neutron matter, which may be relevant to the crust region of a magnetized neutron star. In …

Superconductivity with spin-polarized Cooper pairs is known to emerge by combining
conventional spinless superconductors with materials that have spin-dependent …
