Particle creation in the spin modes of a dynamically oscillating two-component Bose-Einstein condensate
Particle creation in the spin modes of a dynamically oscillating two-component Bose-Einstein condensate
We investigate the parametric amplification of the zero-point fluctuations in the spin modes of a two-component Bose-Einstein condensate, triggered by the dynamical evolution of the condensate density. We first make use of a Thomas-Fermi approximation to develop a tractable theoretical model of the quantum dynamics of the Bogoliubov excitations in …
