We observe condensation of exciton polaritons in quantum states composed of concentric rings when exciting
cylindrical pillar GaAs/AlGaAs microcavities nonresonantly by a focused laser beam normally incident at the
center of the pillar. The number of rings depends on the pumping intensity and the pillar size, andmay achieve 5 in
the pillar of 40 μm diameter. Breaking the axial symmetry when moving the excitation spot away from the pillar
center leads to transformation of the rings into a number of bright lobes corresponding to quantum states with
nonzero angular momenta. The number of lobes, their shape, and location are dependent on the spot position.We
describe the out-of-equilibrium condensation of polaritons in the states with different principal quantum numbers
and angular momenta with a formalism based on Boltzmann-Gross-Pitaevskii equations accounting for repulsion
of polaritons from the exciton reservoir formed at the excitation spot and their spatial confinement by the pillar
boundary.
