Super-Poissonian Squeezed Light in the Ground State of Strongly Coupled Light-matter Systems
Cankut Tasci, Mohammad Hassan, Leon Orlov-Sullivan +2
Strong light-matter coupling enables hybrid states in which photonic and electronic degrees of freedom become correlated even in the ground state. While many-body effects in long-r…

Testing electron-photon exchange-correlation functional performance for many-electron systems under weak and strong light-matter coupling
Iman Ahmadabadi, I-Te Lu, Leonardo A. Cunha +3
We present results of a photon-free exchange-correlation functional within the local density approximation (pxcLDA) for quantum electrodynamics density functional theory (QEDFT) th…
