The thermal Hall effect, where a transverse heat current is generated in response to longitudinal temperature gradient, probes charge-neutral excitations insulating quantum matter. By studying transport the Heisenberg-Kitaev antiferromagnet and spin liquid candidate Na${}_{2}$Co${}_{2}$TeO${}_{6}$, authors find here that magnon polarons, i.e., hybridized phonons magnons produced by spin-lattice coupling, govern sign magnitude of observed signal. This contrast pure theory, which fails capture...

A recent focus of quantum spin liquid (QSL) studies is how disorder/randomness in a QSL candidate affects its true magnetic ground state. The ultimate question whether the survives disorder or leads to "spin-liquid-like" state, such as proposed random-singlet (RS) Since standard feature most candidates, this represents major challenge for candidates. YbMgGaO$_4$, triangular lattice antiferromagnet with effective spin-1/2 Yb$^{3+}$ ions, an ideal system address question, since it shows no...

This plateau, which stabilized fields 8--30 T, realized through exotic nematiclike phase for magnetic applied along all three crystallographic axes, resulting rich anisotropic diagrams. We...
Abstract Anomalous Hall effect (AHE), one of the most important electronic transport phenomena, generally appears in ferromagnetic materials but is rare without magnetic elements. Here, a study La 3 MgBi 5 presented, whose band structure carries multitype Dirac fermions. Although elements are absent , signals AHE can be observed. In particular, anomalous conductivity extremely large, reaching 42,356 Ω −1 cm with an angle 8.8%, largest that has been observed current systems. The suggested to...
