Topological phase transition in an all-optical exciton-polariton lattice
M. Pieczarka, E. Estrecho, S. Ghosh +8
Topological insulators are a class of electronic materials exhibiting robust edge states immune to perturbations and disorder. This concept has been successfully adapted in photoni…
Low-energy collective oscillations and Bogoliubov sound in an exciton-polariton condensate
E. Estrecho, M. Pieczarka, M. Wurdack +6
We report the observation of low-energy, low-momenta collective oscillations of an excitonpolariton condensate in a round "box" trap. The oscillations are dominated by the dipole a…
Spatial distribution of an optically induced excitonic reservoir below exciton-polariton condensation threshold
M. Boozarjmehr, M. Steger, K. West +5
Optical trapping and manipulation of microcavity exciton polaritons rely on effective potentials induced by the interaction of polaritons with a reservoir of high energy excitonic…
Observation of quantum depletion in a nonequilibrium exciton-polariton condensate
Maciej Pieczarka, Eliezer Estrecho, Maryam Boozarjmehr +9
The property of superfluidity, first discovered in liquid 4He, is closely related to Bose-Einstein condensation (BEC) of interacting bosons. However, even at zero temperature, when…
Observation of Non-equilibrium Motion and Equilibration in Polariton Rings
S. Mukherjee, D. M. Myers, R. G. Lena +8
We present a study of the macroscopic dynamics of a polariton condensate formed by non-resonant optical excitation in a quasi-one-dimensional ring-shaped microcavity. The presence…
Direct measurement of polariton-polariton interaction strength in the Thomas-Fermi regime of exciton-polariton condensation
E. Estrecho, T. Gao, N. Bobrovska +12
Bosonic condensates of exciton polaritons (light-matter quasiparticles in a semiconductor) provide a solid-state platform for studies of non-equilibrium quantum systems with a spon…
