Abstract

Researchers at the Institute for Solid State Physics, University of Tokyo, recently proposed a current-induced thermoelectric phenomenon called the “nonlinear anomalous Ettingshausen effect” in organic massive Dirac electron systems. This phenomenon allowed for a novel method of observing the topological nature of Dirac electron systems by inducing the time-reversal-symmetry breaking using an electric current, which can then be detected via simple thermoelectric measurements.
