Superradiant phase transition in the ultrastrong coupling regime of the two-photon Dicke model
L. Garbe, I. L. Egusquiza, E. Solano +4
The controllability of current quantum technologies allows to implement spin-boson models where two-photon couplings are the dominating terms of light-matter interaction. In this c…
Critical behavior of dissipative two-dimensional spin lattices
R. Rota, F. Storme, N. Bartolo +2
We explore critical properties of two-dimensional lattices of spins interacting via an anisotropic Heisenberg Hamiltonian and subject to incoherent spin flips. We determine the ste…
Output squeezed radiation from dispersive ultrastrong light-matter coupling
S. Fedortchenko, S. Huppert, A. Vasanelli +6
We investigate the output generation of squeezed radiation of a cavity photon mode coupled to another off-resonant bosonic excitation. By modulating in time their linear interactio…
All-optical control of the quantum flow of a polariton superfluid
D. Sanvitto, S. Pigeon, A. Amo +12
While photons in vacuum are massless particles that do not interact with each other, significant photon-photon interactions appear in suitable nonlinear media, leading to novel hyd…
Polariton superfluids reveal quantum hydrodynamic solitons
A. Amo, S. Pigeon, D. Sanvitto +9
A quantum fluid passing an obstacle behaves differently from a classical one. When the flow is slow enough, the quantum gas enters a superfluid regime and neither whirlpools nor wa…
Light Engineering of the Polariton Landscape in Semiconductor Microcavities
A Amo, S Pigeon, C Adrados +4
We demonstrate a method to create potential barriers with polarized light beams for polaritons in semiconductor microcavities. The form of the barriers is engineered via the real s…
