Magnonics addresses the dynamic excitations of a magnetically ordered material. These
excitations, referred to as spin waves and their quanta, magnons, are a powerful tool for …

A supercurrent is a macroscopic effect of a phase-induced collective motion of a quantum
condensate. So far, experimentally observed supercurrent phenomena such as …

We present a quantum Hall effect of magnons in two-dimensional clean insulating magnets
at finite temperature. Through the Aharonov-Casher effect, a magnon moving in an electric …

Nambu–Goldstone theorem provides gapless modes to both relativistic and nonrelativistic
systems. The Nambu–Goldstone bosons in insulating magnets are called magnons or spin …

There has been a growing interest in non-Hermitian physics. One of its main goals is to
engineer dissipation and to explore ensuing functionality. In magnonics, the effect of …

Magnetic materials in which it is possible to control the topology of their magnetic order in
real space or the topology of their magnetic excitations in reciprocal space are highly sought …

One of the main goals of spintronics is to improve transport of information carriers and to
achieve new functionalities with ultra-low dissipation. A most promising strategy for this holy …

Without applied bias voltage, a superconducting phase difference can drive a charge
Josephson supercurrent in a superconductor junction. In analogy, we here theoretically …

We show how the interference between superfluid spin currents can endow spin circuits with
coherent logic functionality. While the hydrodynamic aspects of the linear-response …

A spin current—a flow of spin angular momentum—can be carried either by spin-polarized
free electrons or by magnons, the quanta of a moving collective oscillation of localized …
