Photon condensation, Van Vleck paramagnetism, and chiral cavities
Alberto Mercurio, Gian Marcello Andolina, Francesco M. D. Pellegrino +6
We introduce a gauge-invariant model of planar, square molecules coupled to a quantized spatially-varying cavity electromagnetic vector potential A(r). Specifically, we choose a te…
Ultrastrong Magnon-Photon Coupling Achieved by Magnetic Films in Contact with Superconducting Resonators
Alberto Ghirri, Claudio Bonizzoni, Maksut Maksutoglu +4
Coherent coupling between spin wave excitations (magnons) and microwave photons in a cavity may disclose new paths to unconventional phenomena as well as for novel applications. He…
A non-perturbative no-go theorem for photon condensation in approximate models
G. M. Andolina, F. M. D. Pellegrino, A. Mercurio +3
Equilibrium phase transitions between a normal and a photon condensate state (also known as superradiant phase transitions) are a highly debated research topic, where proposals for…
Emergence of entanglement from a noisy environment: The case of polaritons
S. Portolan, O. Di Stefano, S. Savasta +1
We show theoretically that polariton pairs with a high degree of polarization entanglement can be produced through parametric scattering. We demonstrate that it can emerge in coinc…
