- W2761949105 abstract "Strongly localized vorticity is a key ingredient of a broad variety of fluid phenomena, and its quantized version is considered to be the hallmark of superfluidity. Flows that correspond to vortices of a large topological charge, termed are notoriously difficult to realise and even when externally imprinted, they are unstable, breaking into many vortices of a single charge. In spite of many theoretical proposals on the formation and stabilisation of giant vortices in ultra cold atomic Bose-Einstein condensates and other superfluid systems, their experimental realisation remains illusive. Polariton condensates stand out from other superfluid systems due to their particularly strong interparticle interactions combined with their non-equilibrium nature, and as such provide an alternative test-bed for the study of non-trivial vortices. Here, we show that by injecting an odd number of polariton condensates at the vertices of a regular polygon and imposing frustration into the system by controlling the interactions across vertices, stable spatially localized circular energy flows can be formed of non-trivial angular momentum. Multiply-quantized vortices, formed at the centre of a polygon on a non-zero density background, allow for the study of vorticity with large topological charges in superfluids and create a promising platform for analogue gravity." @default.
