Spintronics aims to go beyond the charge-based paradigm of silicon-based microelectronics
by utilizing the spin degree of freedom for memory, storage and computing applications …

Dissipation in mechanics, optics, acoustics, and electronic circuits is nowadays recognized
to be not always detrimental but can be exploited to achieve non-Hermitian topological …

Condensed matter systems admit topological collective excitations above a trivial ground
state, an example being Chern insulators formed by Dirac bosons with a gap at finite …

Spin-polarized antiferromagnets have recently gained significant interest because they
combine the advantages of both ferromagnets (spin polarization) and antiferromagnets …

Topological magnon insulators (TMI) are ordered magnets supporting chiral edge magnon
excitations. These edge states are envisioned to serve as topologically protected information …

Magnonics or magnon spintronics is an emerging field focusing on generating, detecting,
and manipulating magnons. As charge‐neutral quasi‐particles, magnons are promising …

We show that magnetic insulators with a collinear and compensated order can exhibit a
thermal Hall effect even at zero magnetic field if they have altermagnetic symmetries. We …

Linear spin wave theory (LSWT) is the standard technique to compute the spectra of
magnetic excitations in quantum materials. In this Letter, we show that LSWT, even under …

We theoretically propose a realization of nonlinear nonreciprocal transport in
antiferromagnets without relying on the relativistic spin-orbit coupling. Through symmetry …

Ferromagnetic spin valves and tunneling junctions are crucial for spintronics applications
and are one of the most fundamental spintronics devices. Motivated by the potential unique …
