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…
