Giant increase of temporal coherence in optically trapped polariton condensate
Alexis Askitopoulos, Lucy Pickup, Sergey Alyatkin +4
Coherent bosonic ensembles offer the promise of harnessing quantum effects in photonic and quantum circuits. In the dynamic equilibrium regime, the application of polariton condens…
Spontaneous self-ordered states of vortex-antivortex pairs in a Polariton Condensate
F. Manni, T. C. H. Liew, K. G. Lagoudakis +4
Polariton condensates have proved to be model systems to investigate topological defects, as they allow for direct and non-destructive imaging of the condensate complex order param…
Penrose-Onsager Criterion Validation in a One-Dimensional Polariton Condensate
F. Manni, K. G. Lagoudakis, R. André +2
We perform quantum tomography on one-dimensional polariton condensates, spontaneously occurring in linear disorder valleys in a CdTe planar microcavity sample. By the use of optica…
Spontaneous Pattern Formation in a Polariton Condensate
F. Manni, K. G. Lagoudakis, T. C. H. Liew +2
Polariton condensation can be regarded as a self-organization phenomenon, where phase ordering is established among particles in the system. In such condensed systems, further orde…
Polariton Condensation in a One-Dimensional Disordered Potential
F. Manni, K. G. Lagoudakis, B. Pietka +5
We study the coherence and density modulation of a non-equilibrium exciton-polariton condensate in a one-dimensional valley with disorder. By means of interferometric measurements…
Probing the Dynamics of Spontaneous Quantum Vortices in Polariton Superfluids
K. G. Lagoudakis, F. Manni, B. Pietka +6
The experimental investigation of spontaneously created vortices is of utmost importance for the understanding of quantum phase transitions towards a superfluid phase, especially f…
