Exact Solution for A Real Polaritonic System Under Vibrational Strong Coupling in Thermodynamic Equilibrium: Absence of Zero Temperature and Loss of Light-Matter Entanglement

Dominik Sidler, Michael Ruggenthaler, Angel Rubio

The first exact quantum simulation of a real molecular system (HD${}^{+}$) under strong ro-vibrational coupling to a quantized optical cavity mode in thermal equilibrium is presented.…
