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…
Coherent Oscillations in an Exciton-Polariton Josephson Junction
K. G. Lagoudakis, B. Pietka, M. Wouters +2
We report on the observation of spontaneous coherent oscillations in a microcavity polariton bosonic Josephson junction. The condensation of exciton polaritons takes place under in…
Observation of Half Quantum Vortices in an Exciton-Polariton Condensate
K. G. Lagoudakis, T. Ostatnicky, A. V. Kavokin +3
Singly quantized vortices have been already observed in many systems including the superfluid helium, Bose Einstein condensates of dilute atomic gases, and condensates of exciton p…
Dynamics of long-range order in an exciton-polariton condensate
G. Nardin, K. G. Lagoudakis, M. Wouters +6
We report on time resolved measurements of the first order spatial coherence in an exciton polariton Bose-Einstein condensate. Long range spatial coherence is found to set in right…
Exciton-polariton condensation in a natural two dimensional trap
D. Sanvitto, A. Amo, L. Vina +3
Bose Einstein condensation of exciton-polaritons has recently been reported in homogeneous structures only affected by random in-plane fluctuations. We have taken advantage of the…
Control of non-Markovian effects in the dynamics of polaritons in semiconductor microcavities
F. J. Rodriguez, L. Quiroga, C. Tejedor +3
We report on time-resolved photoluminescence from semiconductor microcavities showing that an optically controllable mechanism exists to turn on and off memory effects in a polarit…
Polarization Control of the Non-linear Emission on Semiconductor Microcavities
M. D. Martin, G. Aichmayr, L. Vina +1
The degree of circular polarization () of the non-linear emission in semiconductor microcavities is controlled by changing the exciton-cavity detuning. The polariton relaxatio…
