Giant spin Meissner effect in a non-equilibrium exciton-polariton gas
M. Król, R. Mirek, D. Stephan +7
The suppression of Zeeman energy splitting due to spin-dependent interactions within a Bose-Einstein condensate (the spin Meissner effect) was predicted to occur up to a certain va…
Doubly dressed bosons - exciton-polaritons in a strong terahertz field
B. Piętka, N. Bobrovska, D. Stephan +12
We demonstrate the existence of a novel quasiparticle: an exciton in a semiconductor doubly dressed with two photons of different wavelengths: near infrared cavity photon and terah…
2s exciton-polariton revealed in an external magnetic field
B. Pietka, M. R. Molas, N. Bobrovska +9
We demonstrate the existence of the excited state of an exciton-polariton in a semiconductor microcavity. The strong coupling of the quantum well heavy-hole exciton in an excited 2…
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…
Selective photoexcitation of exciton-polariton vortices
Gaël Nardin, Konstantinos G. Lagoudakis, Barbara Pietka +3
We resonantly excite exciton-polariton states confined in cylindrical traps. Using a homodyne detection setup, we are able to image the phase and amplitude of the confined polarito…
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…
