Spin-polarized spatially indirect excitons in a topological insulator

R Mori, S Ciocys, K Takasan, P Ai, K Currier… - Nature, 2023 - nature.com
The exciton, a bound state of an electron and a hole, is a fundamental quasiparticle induced
by coherent light–matter interactions in semiconductors. When the electrons and holes are …

Recent progress on non-Abelian anyons: from Majorana zero modes to topological Dirac fermionic modes

Y Wu, J Liu, XC ** in excitonic insulators
Z Sun, AJ Millis - Physical Review Letters, 2021 - APS
We show that in excitonic insulators with s-wave electron-hole pairing, an applied electric
field (either pulsed or static) can induce ap-wave component to the order parameter, and …
