New research conducted by Princeton University physicists is delving with high resolution into the complex and fascinating world of topological quantum matter—a branch of physics that studies the ...

Anomalous Hall (AH) effect, which exists in ferromagnetic metals 1,2, means that the electric Hall conductance remains to be finite even at zero external magnetic field. Furthermore, if the system ...

In one sentence: The spin Hall effect is a phenomenon in which an ordinary electric current flowing through a non-magnetic conductor with strong spin-orbit coupling creates a sideways spin current, ...

RIKEN physicists have created an exotic quantum state in a device with a disk-like geometry for the first time, showing that edges are not required. This demonstration opens the way for realizing ...

We first describe how phonon Hall viscosity alters sound propagation through a solid. In crystals with high enough symmetry, and for high-symmetry propagation directions, the two transverse sound ...
