GW and Bethe-Salpeter Theory for Molecular Polaritons, Quasiparticles, and Excitons
Soohaeng Yoo Willow, Gi Beom Sim, Tae Hyeon Park +6
The electron self-energy is central to quasiparticle theory, yet how an optical cavity enters it remains unclear. We address this question for a molecule in a single-mode cavity us…

Two-dimensional Excitonic Photoluminescence in Graphene on Cu surface
Youngsin Park, Yoo S. Kim, Chang Woo Myung +10
Despite having outstanding electrical properties, graphene is unsuitable for optical devices because of its zero band gap. Here, we report two-dimensional excitonic photoluminescen…
