Polymorphic 2D materials allow structural and electronic phase engineering, which can be
used to realize energy-efficient, cost-effective, and scalable device applications. The phase …

In the recent years, the thermal Hall transport has risen as an important diagnosis of the
physical properties of the elementary excitations in various quantum materials, especially …

Phonons are known to generate a thermal Hall effect in certain insulators, including oxides
with rare-earth impurities, quantum paraelectrics, multiferroic materials, and cuprate Mott …

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 …

The thermal transport of magnons has attracted substantial attention as an energy-efficient
alternative to the transport of electrons. Most theoretical studies so far have been carried out …

We investigate the thermal Hall effect in the Heisenberg-Kitaev antiferromagnet Na 2 Co 2
TeO 6, where we observe negative thermal Hall conductivity (THC) with thermal Hall angles …

Thermal transport is a pivotal probe for studying low-energy, charge-neutral quasiparticles in
insulating magnets. In this Letter, we report an observation of large magnetothermal …
