High-efficiency energy harvesting based on nonlinear Hall rectifier
Yugo Onishi, Liang Fu
Noncentrosymmetric quantum materials can convert AC input current into DC transverse current through the nonlinear Hall effect at zero magnetic field. We analyze the AC-DC power co…

Effects of relaxation on photovoltaic effect and possibility of photocurrent within transparent region
Yugo Onishi, Hikaru Watanabe, Takahiro Morimoto +1
We theoretically study photocurrents in metals that break both inversion and symmetries within the transparent region. We find that the system under the…

Theory of shift heat current and its application to electron-phonon coupled systems
Yugo Onishi, Takahiro Morimoto, Naoto Nagaosa
We propose a heat current analog of the shift current, "shift heat current". We study nonlinear heat current responses to an applied ac electric field by a diagrammatic method and…
