Exciton-polariton condensation is regarded as a spontaneous macroscopic quantum
phenomenon with phase ordering and collective coherence. By engineering artificial …

Exciton polariton condensation is a macroscopic quantum state that can be efficiently
controlled by an external field through a nonlinear interaction. In an annular potential …

Superposition states of circular currents of exciton-polaritons mimic the superconducting flux
qubits. The phase of a polariton fluid must change by an integer number of 2 π when going …

Concentric ring exciton polariton condensates emerging under non-resonant laser pump in
an annular trapping potential support persistent circular currents of polaritons. The trapping …

Recent experiments showed the transfer of orbital angular momentum (OAM) from a
nonresonant laser onto an exciton-polariton condensate, despite earlier views that the …

Exciton-polaritons offer a versatile platform for realization of all-optical integrated logic gates
due to the strong effective optical nonlinearity resulting from the exciton–exciton interactions …

We report the observation of low-energy, low-momenta collective oscillations of an exciton-
polariton condensate in a round “box” trap. The oscillations are dominated by the dipole and …

It is now routine to make Bose-Einstein condensates of polaritons with long enough lifetime
and low enough disorder to travel ballistically for hundreds of microns in quasi-one …

The polariton-polariton interaction strength is an important parameter for all kinds of
applications using the nonlinear properties of polaritons, such as optical switching and …

We investigate the spin polarization of localized exciton-polariton condensates. We
demonstrate the presence of an effective magnetic field leading to the formation of elliptically …
