Topological Floquet-Thouless energy pump
Michael H. Kolodrubetz, Frederik Nathan, Snir Gazit +2
We explore adiabatic pumping in the presence of periodic drive, finding a new phase in which the topologically quantized pumped quantity is energy rather than charge. The topologic…
Berry Phases in Symmetry Protected Topological Phases
Toshikaze Kariyado, Takahiro Morimoto, Yasuhiro Hatsugai
We show that the Berry phase (Berry phase quantized into ) provides a useful tool to characterize symmetry protected topological phases with correlation that can be dir…
Nonlinear spin current generation in noncentrosymmetric spin-orbit coupled systems
Keita Hamamoto, Motohiko Ezawa, Kun Woo Kim +2
Spin current plays a central role in spintronics. In particular, finding more efficient ways to generate spin current has been an important issue and studied actively. For example,…
Nonreciprocal current from electron interactions in noncentrosymmetric crystals: roles of time reversal symmetry and dissipation
Takahiro Morimoto, Naoto Nagaosa
In noncentrosymmetric crystals with broken inversion symmetry , the (: current, : voltage) characteristic is generally expected to depend on the direction…
Floquet topological phases protected by time glide symmetry
Takahiro Morimoto, Hoi Chun Po, Ashvin Vishwanath
We study Floquet topological phases in periodically driven systems that are protected by "time glide symmetry", a combination of reflection and half time period translation. Time g…
Quantitative relationship between polarization differences and the zone-averaged shift photocurrent
Benjamin M. Fregoso, Takahiro Morimoto, Joel E. Moore
A relationship is derived between differences in electric polarization between bands and the "shift vector" that controls part of a material's bulk photocurrent, then demonstrated…
