Symmetry selection rule for the band-edge shift current in two dimensions
Felipe Pérez Riffo, Felipe Pérez Riffo, Matías Castro +5
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…
Precision-Induced Irreversibility in non-Hermitian systems
Luis E. F. Foa Torres, G. Pappas, V. Achilleos +1
The paper investigates how finite numerical or experimental precision creates a predictability horizon in non‑Hermitian quantum systems, leading to precision‑induced irreversibilit…
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…
Universal critical timescales in slow non-Hermitian dynamics
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…
Spin precession and laser-induced spin-polarized photocurrents
Esteban A. RodrÃguez-Mena, MatÃas 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…
Nonsymmetric evanescent coupling in photonics
Rodrigo A. Vicencio, Diego Román-Cortés, Martın Rubio-SaldÃas +2
Asymmetrical interactions are ubiquitous in nature, and in physics their study becomes fundamental. Despite the prevalence of evanescent coupling in physics, little attention has b…
