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…
Charge waves and dynamical signatures of topological phases in Su-Schrieffer-Heeger chains
Tomasz Kwapinski, Marcin Kurzyna, Luis E. F. Foa Torres
We investigate the emergence of charge waves and their temporal dynamics in one-dimensional Su-Schrieffer-Heeger (SSH) topological chains. Contrary to the conventional view that ch…
Critical timescales for chiral state conversion and irreversibility
Giorgos Pappas, Diego Bautista Avilés, Luis E. F. Foa Torres +1
Non-Hermitian systems driven along slow parametric loops undergo non-adiabatic transitions whose outcome depends sensitively on the driving speed, yet no explicit formula has been…
Precision-Induced Irreversibility in non-Hermitian systems
Luis E. F. Foa Torres, G. Pappas, V. Achilleos +1
Non-Hermitian evolution is mathematically invertible, yet finite dynamic range imposes a sharp operational limit on reversibility. We identify Precision-Induced Irreversibility (PI…
Spin precession and laser-induced spin-polarized photocurrents
Esteban A. Rodríguez-Mena, Matías Berdakin, Luis E. F. Foa Torres
Controlling spin currents in topological insulators (TIs) is crucial for spintronics but challenged by the robustness of their chiral edge states, which impedes the spin manipulati…
Engineering Floquet moiré patterns for scalable photocurrents
Hernan L. Calvo, Luis E. F. Foa Torres, Matias Berdakin
While intense laser irradiation and moiré engineering have independently proven powerful for tuning material properties on demand in condensed matter physics, their combination rem…
