Spacetime analog of Bose-Einstein condensates: Bogoliubov–de Gennes formulation |
|
Abstract |
We construct quantum field theory in an analog curved spacetime in Bose-Einstein condensates based on the Bogoliubov–de Gennes equations by exactly relating quantum particles in curved spacetime with Bogoliubov quasiparticle excitations in Bose-Einstein condensates. We numerically investigate particle creation by solving the Bogoliubov–de Gennes equation in an inhomogeneous condensate. |
