Ghost Branch Photoluminescence From a Polariton Fluid Under Nonresonant Excitation.
An expanding polariton condensate is investigated under pulsed nonresonant excitation with a small laser pump spot. Far above the condensation threshold we observe a pronounced increase in the dispersion curvature, with a subsequent linearization of the spectrum and strong luminescence from a ghost branch orthogonally polarized with respect to the linearly polarized condensate emission. Polariz...

متن کاملSpinor Bose Condensates in Optical Traps
In an optical trap, the ground state of spin-1 Bosons such as 23Na, 39K, and 87Rb can be either a ferromagnetic or a “polar” state, depending on the scattering lengths in different angular momentum channel. The collective modes of these states have very different spin character and spatial distributions. While ordinary vortices are stable in the polar state, only those with unit circulation are...
متن کاملSpinor Bose-Einstein condensates in optical traps
We have studied the equilibrium state of spinor condensates in an optical trap [1]. In contrast to magnetically trapped condensates, spinor condensates have the orientation of the spin as a degree of freedom, which can be described by a multi-component wavefunction (one for each magnetic sublevel). In an F=1 spinor condensate subject to spin relaxation, two mF=0 atoms can collide and produce a ...
متن کاملOptical bistability in a GaAs-based polariton diode.
We report on a new type of optical nonlinearity in a polariton p-i-n microcavity. Abrupt switching between the strong and weak coupling regime is induced by controlling the electric field within the cavity. As a consequence, bistable cycles are observed for low optical powers (2-3 orders of magnitude less than for Kerr induced bistability). Signatures of switching fronts propagating through the...
