Exciton vortices in two-dimensional hybrid perovskite monolayers
Yingda Chen, Dong Zhang, Kai Chang
We study theoretically the exciton Bose-Einstein condensation and exciton vortices in a two-dimensional (2D) perovskite (PEA)2PbI4 monolayer. Combining the first-principles calcula…

Geometric photon-drag effect and nonlinear shift current in centrosymmetric crystals
Li-kun Shi, Dong Zhang, Kai Chang +1
The nonlinear shift current, also known as the bulk photovoltaic current generated by linearly polarized light, has long been known to be absent in crystals with inversion symmetry…
