Abstract: Significance We find that the amplitude of the thermal Hall effect (THE) in strontium titanate drastically varies with atomic substitution. It is suppressed when Sr is substituted by Ca, pointing to the role of ferroelectric… read more here.

Abstract: The topological effect in thermoelectric transport is an important research aspect in semimetals, but whether an anomalous Nernst effect exists in nonmagnetic topological semimetals in a finite external field is still under debate. To demonstrate… read more here.
