Geometric aspects of nonlinear and nonequilibrium phenomena
Takahiro Morimoto, Sota Kitamura, Naoto Nagaosa
We review recent developments in the research of nonlinear and nonequilibrium phenomena in solids focusing on their geometrical aspects. We start with introducing the basic concept…
Photocurrent induced by a bicircular light drive in centrosymmetric systems
Yuya Ikeda, Sota Kitamura, Takahiro Morimoto
A bicircular light (BCL) consists of left and right circularly polarized lights with different frequencies, and draws a rose-like pattern with a rotational symmetry determined by t…
Giant Magnetochiral Anisotropy in Weyl-semimetal WTe2 Induced by Diverging Berry Curvature
Tomoyuki Yokouchi, Yuya Ikeda, Takahiro Morimoto +1
The concept of Berry curvature is essential for various transport phenomena. However, an effect of the Berry curvature on magnetochiral anisotropy, i.e. nonreciprocal magneto-trans…
Gap labeling theorem for multilayer thin film heterostructures
Mao Yoshii, Sota Kitamura, Takahiro Morimoto
Quasiperiodic systems show a universal gap structure due to quasiperiodicity which is analogous to gap openings at the Brillouin zone boundary in periodic systems. The integrated d…
Nonlinear spin current of photoexcited magnons in collinear antiferromagnets
Kosuke Fujiwara, Sota Kitamura, Takahiro Morimoto
We study the nonlinear magnon spin current induced by an ac electric field under light irradiation in collinear antiferromagnets with broken inversion symmetry. For linearly polari…
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…
