Exact vortex decomposition of the shift current
Matias Castro Schnaidt, Felipe Perez Riffo, Juan M. Florez +1
Does any integer survive in the shift current, and does the Chern number control its sign? We show that the shift vector is a singular field on the Brillouin torus. Its curl has tw…
Topographic Disorder, Wind Coupling, and Directional Fire Spread: Critical Behavior in a Terrain-Weighted Forest Fire Model
Juan M. Florez, Eric Suárez Morell, Cristian Millan +1
We introduce the Terrain-Weighted Forest Fire Model (TFFM), a lattice model in which fire spreads on a spatially correlated Gaussian height field with the asymmetric bond probabili…
Symmetry selection rule for the band-edge shift current in two dimensions
Felipe Pérez Riffo, Matías Castro, Leonor Chico +2
The shift current is the intrinsic bulk photovoltaic response of a crystal without an inversion center. In graphene multilayers, calculations report large band-edge shift currents…
