It is known that the fundamental mode of rotation in quantum fluids is represented by a quantum vortex. Its quantized value represents the orbital angular momentum (OAM) per particle, which is…

### Temporal shaping and time-varying orbital angular momentum of displaced vortices

- Physics
- 2020

The fundamental mode of rotation in quantum fluids is given by a vortex whose quantized value yields the orbital angular momentum (OAM) per particle. If the vortex is displaced (off-centered) from…

We study theoretically the second-order coherence g(2)(0) of light emitted by polariton lasers, i.e., devices based on stimulated relaxation and condensation of exciton–polaritons in microcavities.…

### Keldysh field theory for nonequilibrium condensation in a parametrically pumped polariton system

- Physics

It is demonstrated that any nonzero detuning results in oscillations of the relative phase of the photon and exciton macroscopic wave functions.

- PhysicsScientific reports
- 2016

The dynamics of coupled condensates is a wide-encompassing problem with relevance to superconductors, BECs in traps, superfluids, etc, and a unified picture is provided that includes detuning of the free energies, different self-interaction strengths and finite lifetime of the modes.

We consider Bose-Einstein condensation of photons in an optical cavity filled with dye molecules that are excited by laser light. By using the Schwinger-Keldysh formalism we derive a Langevin field…

### Bose-Einstein Condensation of Microcavity Polaritons in a Trap

- PhysicsScience
- 2007

Polaritons are created in a harmonic potential trap analogous to atoms in optical traps and observe a number of signatures of Bose-Einstein condensation: spectral and spatial narrowing, a peak at zero momentum in the momentum distribution, first-order coherence, and spontaneous linear polarization of the light emission.

### Quantum kinetic derivation of the nonequilibrium Gross-Pitaevskii equation for nonresonant excitation of microcavity polaritons

- Physics

The space and time dependent nonequilibrium Keldysh-Green functions are employed to derive the scattering rates between the condensed microcavity polaritons described by a Gross-Pitaevskii equation…

### Superfluidity and critical velocities in nonequilibrium Bose-Einstein condensates.

- PhysicsPhysical review letters
- 2010

The drag force on a small moving object and the onset of fringes in the density profile are shown to have a sharp threshold as a function of the velocity; a generalized Landau criterion is developed to explain this behavior in terms of the dispersion of elementary excitations.
