Strain-assisted optomechanical coupling of polariton condensate spin to a micromechanical resonator
O. Be'er, H. Ohadi, Y. del Valle-Inclan Redondo +5
We report spin and intensity coupling of an exciton-polariton condensate to the mechanical vibrations of a circular membrane microcavity. We optically drive the microcavity resonat…
Spin order and phase transitions in chains of polariton condensates
H. Ohadi, A. J. Ramsay, H. Sigurdsson +8
We demonstrate that multiply-coupled spinor polariton condensates can be optically tuned through a sequence of spin-ordered phases by changing the coupling strength between nearest…
Inverse-phase Rabi oscillations in semiconductor microcavities
A. V. Trifonov, N. E. Kopteva, M. V. Durnev +7
We study experimentally the oscillations of a non stationary transient signal of a semiconductor microcavity with embedded InGaAs quantum wells. The oscillations occur as a result…
Tunable magnetic alignment between trapped exciton-polariton condensates
H. Ohadi, Y. del Valle-Inclan Redondo, A. Dreismann +6
Tunable spin correlations are found to arise between two neighboring trapped exciton-polariton condensates which spin-polarize spontaneously. We observe a crossover from an antifer…
Dynamics of the Energy Relaxation in a Parabolic Quantum Well Laser
A. V. Trifonov, E. D. Cherotchenko, J. L. Carthy +6
We explore two parabolic quantum well (PQW) samples, with and without Bragg mirrors, in order to optimise the building blocks of a Bosonic Cascade Laser. The photoluminescence spec…
Spontaneous spin bifurcations and ferromagnetic phase transitions in a spinor exciton-polariton condensate
H. Ohadi, A. Dreismann, Y. G. Rubo +6
We observe a spontaneous parity breaking bifurcation to a ferromagnetic state in a spatially trapped exciton-polariton condensate. At a critical bifurcation density under nonresona…
