Surface lone-pair polarization probed by quantum-geometric transport in tellurium
Nathanael N. Batista, Wendel S. Paz, Manuel Suárez-RodrÃguez +10
Stereochemically active lone pairs are ubiquitous microscopic sources of polarity in molecules and solids, but their collective behavior in crystals is often hidden by symmetry or…
Angular-resolved nonlinear optical response as a probe of Lorentz violation in noncentrosymmetric materials
Guilherme J. Inacio, Nathanael N. Batista, Wesley Spalenza +3
We propose a methodology to detect weak Lorentz-violating (LV) backgrounds through the nonlinear shift photocurrent in noncentrosymmetric crystals. Using a spinful Rice--Mele model…
Enabling the bulk photovoltaic effect in centrosymmetric materials through an external electric field
Guilherme J. Inacio, Juan José Esteve-Paredes, MaurÃcio F. C. Martins Quintela +2
We develop a practical approach to electrically tuning the nonlinear photoresponse of two-dimensional semiconductors by explicitly incorporating a static out-of-plane electric fiel…
