DOI: 10.1038/s41467-019-10625-y
Abstract: Electric current has been used to send electricity to far distant places. On the other hand, spin current, a flow of electron spin, can in principle also send angular momentum to distant places. In a… read more here.

DOI: 10.1038/s41467-021-24623-6
Abstract: Thermoelectric effects have been applied to power generators and temperature sensors that convert waste heat into electricity. The effects, however, have been limited to electrons to occur, and inevitably disappear at low temperatures due to… read more here.

DOI: 10.1103/physrevb.98.020401
Abstract: We theoretically propose a nonreciprocal spin Seebeck effect, i.e., nonreciprocal spin transport generated by a temperature gradient, in bulk antiferromagnetic insulators with broken inversion symmetry. We find that nonreciprocity in antiferromagnets has rich properties not… read more here.
