Pulse, polarization and topology shaping of polariton fuids
Lorenzo Dominici, David Colas, Stefano Donati +9
Here we present different approaches to ultrafast pulse and polarization shaping, based on a ``quantum fluid'' platform of polaritons. Indeed we exploit the normal modes of two dim…
Full and fractional defects across the Berezinskii-Kosterlitz-Thouless transition in a driven-dissipative spinor quantum fluid
G. Dagvadorj, P. Comaron, M. H. Szymanska
We investigate the properties of a two-dimensional \emph{spinor} microcavity polariton system driven by a linearly polarised continuous pump. In particular, we establish the role o…
Unconventional Berezinskii-Kosterlitz-Thouless Transition in the Multicomponent Polariton System
G. Dagvadorj, P. Comaron, M. H. Szymanska
We study a four-component polariton system in the optical parametric oscillator regime consisting of exciton/photon and signal/idler modes across the Berezinskii-Kosterlitz-Thoules…
First-order dissipative phase transition in an exciton-polariton condensate
Galbadrakh Dagvadorj, Michal Kulczykowski, Marzena H. Szymanska +1
We investigate the phase diagram of a two-dimensional driven-dissipative system of polaritons coupled to the excitonic reservoir. We find that two critical points exists. The first…
Searching for the Kardar-Parisi-Zhang phase in microcavity polaritons
A. Ferrier, A. Zamora, G. Dagvadorj +1
Recent approximate analytical work has suggested that, at certain values of the external pump, the optical parametric oscillator (OPO) regime of microcavity polaritons may provide…
Kibble-Zurek mechanism in driven-dissipative systems crossing a non-equilibrium phase transition
A. Zamora, G. Dagvadorj, P. Comaron +3
The Kibble-Zurek mechanism constitutes one of the most fascinating and universal phenomena in the physics of critical systems. It describes the formation of domains and the spontan…
Dynamically Tuned Arrays of Polariton Parametric Oscillators
Alexander S. Kuznetsov, Galbadrakh Dagvadorj, Klaus Biermann +2
Optical parametric oscillations (OPOs) - a non-linear process involving the coherent coupling of an optically excited two particle pump state to a signal and an idler states with d…
Directional Goldstone waves in polariton condensates close to equilibrium
Dario Ballarini, Davide Caputo, Galbadrakh Dagvadorj +8
Quantum fluids of light are realized in semiconductor microcavities by exciton-polaritons, solid-state quasi-particles with a light mass and sizeable interactions. Here, we use the…
Properties of the signal mode in the polariton OPO regime
K. Dunnett, A. Ferrier, A. Zamora +2
Theoretical analyses of the polariton optical parametric oscillator (OPO) regime often rely on a mean field approach based on the complex Gross-Pitaevskii equations in a three-mode…
Twist of generalized skyrmions and spin vortices in a polariton superfluid
Stefano Donati, Lorenzo Dominici, Galbadrakh Dagvadorj +7
We study the spin vortices and skyrmions coherently imprinted into an exciton-polariton condensate on a planar semiconductor microcavity. We demonstrate that the presence of a pola…
Topological order and equilibrium in a condensate of exciton-polaritons
Davide Caputo, Dario Ballarini, Galbadrakh Dagvadorj +9
We report the observation of the Berezinskii-Kosterlitz-Thouless transition for a 2D gas of exciton-polaritons, and through the joint measurement of the first-order coherence both…
Non-equilibrium Berezinskii-Kosterlitz-Thouless Transition in a Driven Open Quantum System
G. Dagvadorj, J. M. Fellows, S. Matyjaskiewicz +3
The Berezinskii-Kosterlitz-Thouless mechanism, in which a phase transition is mediated by the proliferation of topological defects, governs the critical behaviour of a wide range o…
