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…
Excitonic interactions and mechanism for ultrafast interlayer photoexcited response in van der Waals heterostructures
Chen Hu, Mit H. Naik, Yang-Hao Chan +1
Optical dynamics in van der Waals heterobilayers is of fundamental scientific and practical interest. Based on a time-dependent adiabatic GW approach, we discover a new many-electr…
Engineering Robust Metallic Zero-Mode States in Olympicene Graphene Nanoribbons
Ryan D. McCurdy, Aidan Delgado, Jingwei Jiang +7
Metallic graphene nanoribbons (GNRs) represent a critical component in the toolbox of low-dimensional functional materials technolo-gy serving as 1D interconnects capable of both e…
Giant self-driven exciton-Floquet signatures in time-resolved photoemission spectroscopy of MoS from time-dependent GW approach
Y. -H. Chan, Diana Y. Qiu, Felipe H. da Jornada +1
Time-resolved, angle-resolved photoemission spectroscopy (TR-ARPES) is a one-particle spectroscopic technique that can probe excitons (two-particle excitations) in momentum space.…
Low Energy Excitations in a [4]Triangulene Honeycomb Antiferromagnet
Aidan Delgado, Carolin Dusold, James Wu +5
Carbon-based synthetic lattices offer a versatile platform for the realization and control of correlated quantum effects at the nanoscale. Advances in on-surface synthesis have fac…
