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 ...

To gain further insight into the observed in-plane Hall effect, we analysed a scaling relation between the in-plane Hall conductivity and the longitudinal conductivity. Considering two sources of ...

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, ...
