Vortex stability and permanent flow in nonequilibrium polariton condensates
G. Tosi, D. Sanvitto, M. Baudisch +6
We study the effects of imprinting a single-quantized vortex on the steady state of a microcavity exciton-polariton condensate generated via parametric scattering. Interestingly we…
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…
Pauli blockade of the electron spin flip in bulk GaAs
A. Amo, L. Vina, P. Lugli +3
By means of time-resolved optical orientation under strong optical pumping, the k-dependence of the electron spin-flip time (t_sf) in undoped GaAs is experimentally determined. t_s…
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…
Spin Dynamics of Cavity Polaritons
M. D. Martin, L. Vina, J. K. Son +1
We have studied polariton spin dynamics in a GaAs/AlGaAs microcavity by means of polarization- and time-resolved photoluminescence spectroscopy as a function of excitation density…
