Thermoelectric conversion devices offer a promising route for sustainable heat-to-energy conversion. They are particularly attractive for recovering energy from waste heat, such as that produced by ...

In this work, we experimentally demonstrate for the first time the spontaneous generation of two-dimensional exciton-polariton X-waves. X-waves belong to the family of localized packets that can ...

For the first time in the world, a joint research team from NIMS, Nagoya University and The University of Tokyo has successfully observed the transverse Thomson effect—a phenomenon in which metals or ...
