Superradiant droplet emission from parametrically excited cavities
ORAL
Abstract
Superradiance occurs when a collection of atoms exhibits cooperative, spontaneous emission of
photons at a rate that exceeds that of its component parts. Here, we reveal a similar phenomenon
in a hydrodynamic system consisting of a pair of vibrationally-excited cavities, coupled through
their common wavefield, that spontaneously emit droplets via interfacial fracture. We show that
the droplet emission rate of two coupled cavities is higher than the emission rate of two isolated
cavities. We further show that the amplified emission rate varies sinusoidally with distance between
the cavities, thus demonstrating a hydrodynamic phenomenon that captures the essential features
of superradiance in optical systems.
