Physique

About carrier's self-trapping and dynamical Rashba splitting in the two-dimensional hybrid perovskite (BA)$_2$(MA)$_2$Pb$_3$I$_{10}$

Time- and Angle-Resolved Photoelectron Spectroscopy (tr-ARPES) is employed to monitor photoexcited electrons in the two-dimensional hybrid perovskite (BA)$_2$(MA)$_2$Pb$_3$I$_{10}$. Photoelectron intensity maps are in good agreement with ab-initio…

Non-Euclidean Photonics: Pseudosphere and Black Hole Microlasers

Hyperbolic surfaces are surfaces with negative curvature. Theoretical studies of such surfaces have been extensive over the past century. In particular, within the context of quantum chaos, hyperbolic surfaces can exhibit strong chaotic behavior [1]…
