Understanding superradiant phenomena with synthetic vector potentials in atomic Bose-Einstein condensates
Luca Giacomelli, Iacopo Carusotto
We theoretically investigate superradiance effects in quantum field theories in curved space-times by proposing an analogue model based on Bose--Einstein condensates subject to a s…

Ergoregion instabilities in rotating two-dimensional Bose--Einstein condensates: new perspectives on the stability of quantized vortices
Luca Giacomelli, Iacopo Carusotto
We investigate the stability of vortices in two-dimensional Bose--Einstein condensates. In analogy with rotating spacetimes and with a careful account of boundary conditions, we sh…
