Quantum vacuum properties of the intersubband cavity polariton field
We present a quantum description of a planar microcavity photon mode strongly coupled to a semiconductor intersubband transition in presence of a two-dimensional electron gas. We show that, in thisExpand
Topological Photonics.
Topological photonics is a rapidly emerging field of research in which geometrical and topological ideas are exploited to design and control the behavior of light. Drawing inspiration from theExpand
Excitations in a nonequilibrium Bose-Einstein condensate of exciton polaritons.
TLDR
A mean-field theory of the dynamics of a nonequilibrium Bose-Einstein condensate of exciton polaritons in a semiconductor microcavity is developed and a diffusive behavior of the Goldstone mode is found in the spatially homogeneous case. Expand
Superfluidity of polaritons in semiconductor microcavities
Similar to atoms in cold gases, exciton–polaritons in semiconductor microcavities can undergo Bose–Einstein condensation. A striking consequence of the appearance of macroscopic coherence in theseExpand
25pRB-4 On the origin of strong photon antibunching in weakly nonlinear photonic molecules
In a recent work [Liew and Savona, Phys. Rev. Lett. 104, 183601 (2010)] it was numerically shown that a resonantly driven photonic ''molecule'' consisting of two coupled cavities can exhibit strongExpand
Spatial and spectral shape of inhomogeneous nonequilibrium exciton-polariton condensates
We develop a mean-field theory of the spatial profile and the spectral properties of polariton condensates in nonresonantly pumped semiconductor microcavities in the strong coupling regime. SpecificExpand
Quantized vortices in an exciton–polariton condensate
When a superfluid—such as liquid helium—is set in rotation, vortices appear in which circulation around a closed loop can take only discrete values. Such quantized vortices have now been observed inExpand
Polariton Superfluids Reveal Quantum Hydrodynamic Solitons
TLDR
Using an interacting Bose gas of exciton-polaritons in a semiconductor microcavity, the transition from superfluidity to the hydrodynamic formation of oblique dark solitons and vortex streets in the wake of a potential barrier is reported. Expand
Quantum fluid effects and parametric instabilities in microcavities
We present a description of the non-equilibrium properties of a microcavity polariton fluid, injected by a nearly-resonant continuous wave pump laser. In the first part, we point out the interplayExpand
Nonlocal density correlations as a signature of Hawking radiation from acoustic black holes
We have used the analogy between gravitational systems and nonhomogeneous fluid flows to calculate the density-density correlation function of an atomic Bose-Einstein condensate in the presence of anExpand
