Abstract
We show that exciton-polariton condensates may exhibit a new fundamental,
self-localized nonlinear excitation not seen in other quantum hydrodynamical
systems, which takes the form of a dark ring shaped breather. We predict that
these structures form spontaneously and remain stable under a combination of
uniform resonant and nonresonant forcing. We study single ring dynamics, ring
interactions and ring turbulence, and explain how direct experimental
observations might be made. We discuss the statistics of ring formation and
propose an experimental scheme by which these structures may be exploited to
study the smooth cross-over between equilibrium and non-equilibrium critical
phase transitions. Finally, we present an alternative mechanism of formation
for these topological breathers, in which they circumscribe Gaussian resonant
pumps. The observation of a breathing ring soliton would represent the first
fundamental breathing soliton within the broad field of quantum hydrodynamics.
