Description
Rotational superradiance has long been associated with black holes—but it can actually emerge in any system featuring an ergoregion. The aim of this work is to show that rotating polariton quantum fluids provide a powerful platform to observe this phenomenon, as here one may study ergoregions in isolation (i.e without a horizon). Because ergoregions are intrinsically unstable, they generate dynamical instabilities that are tightly linked to superradiance. We demonstrate via numerical simulations that such instabilities are indeed present in this rotating system of polaritons, showing that experimental measurement of superradiance in such a system may soon be achieved.
