Dynamically enriched topological orders in driven two-dimensional systems
Andrew C. Potter, Takahiro Morimoto
Time-periodic driving of a quantum system can enable new dynamical topological phases of matter that could not exist in thermal equilibrium. We investigate two related classes of d…
Quantized circular photogalvanic effect in Weyl semimetals
Fernando de Juan, Adolfo G. Grushin, Takahiro Morimoto +1
The circular photogalvanic effect (CPGE) is the part of a photocurrent that switches depending on the sense of circular polarization of the incident light. It has been consistently…
Chiral Floquet Phases of Many-body Localized Bosons
Hoi Chun Po, Lukasz Fidkowski, Takahiro Morimoto +2
We construct and classify chiral topological phases in driven (Floquet) systems of strongly interacting bosons, with finite-dimensional site Hilbert spaces, in two spatial dimensio…
Large bulk photovoltaic effect and spontaneous polarization of single-layer monochalcogenides
Tonatiuh Rangel, Benjamin M. Fregoso, Bernardo S. Mendoza +3
We use a first-principles density functional theory approach to calculate the shift current and linear absorption of uniformly illuminated single-layer Ge and Sn monochalcogenides.…
Semiclassical theory of nonlinear magneto-optical responses with applications to topological Dirac/Weyl semimetals
Takahiro Morimoto, Shudan Zhong, Joseph Orenstein +1
We study nonlinear magneto-optical responses of metals by a semiclassical Boltzmann equation approach. We derive general formulas for linear and second order nonlinear optical effe…
Giant anisotropic nonlinear optical response in transition metal monopnictide Weyl semimetals
Liang Wu, S. Patankar, T. Morimoto +6
Although Weyl fermions have proven elusive in high-energy physics, their existence as emergent quasiparticles has been predicted in certain crystalline solids in which either inver…
