Realistic ab initio predictions of excimer behavior under collective light-matter strong coupling
Matteo Castagnola, Marcus T. Lexander, Henrik Koch
Experiments show that light-matter strong coupling affects chemical properties, though the underlying mechanism remains unclear. We present an ab initio quantum electrodynamics cou…
