Phonon screening and dissociation of excitons at finite temperatures from first principles
Antonios M. Alvertis, Jonah B. Haber, Zhenglu Li +4
The properties of excitons, or correlated electron-hole pairs, are of paramount importance to optoelectronic applications of materials. A central component of exciton physics is th…
Anomalous excitonic phase diagram in band-gap-tuned Ta2Ni(Se,S)5
Cheng Chen, Weichen Tang, Xiang Chen +17
During a band-gap-tuned semimetal-to-semiconductor transition, Coulomb attraction between electrons and holes can cause spontaneously formed excitons near the zero-band-gap point,…
Electron-phonon coupling from GW perturbation theory: Practical workflow combining BerkeleyGW, ABINIT, and EPW
Zhenglu Li, Gabriel Antonius, Yang-Hao Chan +1
We present a workflow of practical calculations of electron-phonon (e-ph) coupling with many-electron correlation effects included using the GW perturbation theory (GWPT). This wor…
Imaging Moiré Excited States with Photocurrent Tunneling Microscopy
Hongyuan Li, Ziyu Xiang, Mit H. Naik +12
Moiré superlattices provide a highly tunable and versatile platform to explore novel quantum phases and exotic excited states ranging from correlated insulators1-17 to moiré excito…
