Perfect Intrinsic Squeezing at the Superradiant Phase Transition Critical Point
Kenji Hayashida, Takuma Makihara, Nicolas Marquez Peraca +4
The ground state of the photon-matter coupled system described by the Dicke model is found to be perfectly squeezed at the quantum critical point of the superradiant phase transiti…

Magnonic Superradiant Phase Transition
Motoaki Bamba, Xinwei Li, Nicolas Marquez Peraca +1
We show that the low-temperature phase transition in ErFeO3 that occurs at a critical temperature of ~ 4 K can be described as a magnonic version of the superradiant phase transiti…
