The long fascination that antiferromagnetic materials has exerted on the scientific community
over about a century has been entirely renewed recently with the discovery of several …

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 …

The quantum Hall effect in two-dimensional electron gases involves the flow of topologically
protected dissipationless charge currents along the edges of a sample. Integer or fractional …

A key feature of quantum spin liquids is the predicted formation of fractionalized excitations.
They are expected to produce changes in the physical response, providing a way to observe …

The Kitaev quantum spin liquid displays the fractionalization of quantum spins into Majorana
fermions. The emergent Majorana edge current is predicted to manifest itself in the form of a …

The origin of phonon thermal Hall Effect (THE) observed in a variety of insulators is yet to be
identified. Here, we report on the observation of a thermal Hall conductivity in a non …

It has been known for more than a decade that phonons can produce an off-diagonal
thermal conductivity in the presence of a magnetic field. Recent studies of thermal Hall …

Two-dimensional (2D) van der Waals (vdW) magnets have been a fertile playground for the
discovery and exploration of physical phenomena and new physics. In this Letter, we report …

The nature of the pseudogap phase of the copper oxides ('cuprates') remains a puzzle.
Although there are indications that this phase breaks various symmetries, there is no …

We propose a new mechanism for the thermal Hall effect in exchange spin-wave systems,
which is induced by the magnon-phonon interaction. Using symmetry arguments, we first …
