Conformal versus non-conformal two-Higgs-doublet model: phase transitions and gravitational waves
Nico Benincasa, Ji-Wei Li, Hanxiao Pu +4
In this work we investigate the CP-conserving two-Higgs-doublet model (2HDM) in two realizations: a classically conformal setup (C2HDM) and a non-conformal setup with explicit tree…

Quantum phase transition in a quantum Rabi square with next-nearest-neighbor hopping
Yilun Xu, Feng-Xao Sun, Qiongyi He +2
We propose a quantum Rabi square model where both the nearest-neighbor and the next-nearest-neighbor photon hopping are allowed among four quantum Rabi systems located at the verti…

Phase transition and multistability in Dicke dimer
Yilun Xu, Feng-Xiao Sun, Wei Zhang +2
The exotic phase transitions and multistabilities in atom-cavity coupled systems have attracted tremendous interests recently. In this work, we investigate the effect of photon hop…
