Superfluid light in propagating geometries
Iacopo Carusotto
We review how the paraxial approximation naturally leads to a hydrodynamic description of light propagation in a Kerr nonlinear medium analogous to the Gross-Pitaevskii equation fo…
Probing few-particle Laughlin states of photons via correlation measurements
R. O. Umucalilar, M. Wouters, I. Carusotto
We propose methods to create and observe Laughlin-like states of photons in a strongly nonlinear optical cavity. Such states of strongly interacting photons can be prepared by pump…
Spectrum and entanglement of phonons in quantum fluids of light
Xavier Busch, Iacopo Carusotto, Renaud Parentani
We study the quantum state of phonons propagating on top of a fluid of light coherently generated in a planar microcavity device by a quasi-resonant incident laser beam. In the ste…
Direct observation of Dirac cones and a flatband in a honeycomb lattice for polaritons
Thibaut Jacqmin, Iacopo Carusotto, Isabelle Sagnes +7
Two-dimensional lattices of coupled micropillars etched in a planar semiconductor microcavity offer a workbench to engineer the band structure of polaritons. We report experimental…
Entangled phonons in atomic Bose-Einstein condensates
Stefano Finazzi, Iacopo Carusotto
We theoretically study the entanglement between phonons spontaneously generated in atomic Bose-Einstein condensates by analog Hawking and dynamical Casimir processes. The quantum e…
Anomalous and Quantum Hall Effects in Lossy Photonic Lattices
Tomoki Ozawa, Iacopo Carusotto
We theoretically discuss analogues of the anomalous and the integer quantum Hall effect in driven-dissipative two-dimensional photonic lattices in the presence of a synthetic gauge…
