Origins of electromagnetic anisotropy in monolayer black phosphorus
Pengke Li
Contrary to empirical observations, lowest-order theory predicts that monolayer black phosphorus ("phosphorene") is completely immune to zigzag-polarized optical ex…

Interpreting current-induced spin polarization in topological insulator surface states
Pengke Li, Ian Appelbaum
Several recent experiments on three-dimensional topological insulators claim to observe a large charge current-induced non-equilibrium ensemble spin polarization of electrons in th…

Spin-dependent optical properties in strained silicon and germanium
Pengke Li, Dhara Trivedi, Hanan Dery
We present a comprehensive theory of the circularly polarized luminescence and its dependence on strain in spin-polarized Si and Ge. Symmetries of wavefunctions and interactions ar…
