Many-Body-Driven Ultrafast Exciton Relaxation Enabled by Phonon-Activated Coulomb Coupling
feeds.aps.org · By Xiang Jiang & Jin Zhao ·
The Brief
- The study examines the role of Coulomb interactions in nonequilibrium exciton relaxation, a topic the authors say has remained unexplored.
- The work uses first-principles real-time Bethe-Salpeter formalism combined with nonadiabatic molecular dynamics.
- The authors are Xiang Jiang and Jin Zhao, and the paper is identified by DOI 10.1103/zpbg-7137.
Why it matters
It proposes a many-body, phonon-assisted mechanism for how excitons relax after excitation, which may matter for modelling ultrafast optical and electronic processes in materials. The source excerpt is truncated, so the reported results are not available here.
