Phonon Laser Effect and Dicke-Hepp-Lieb Superradiant Phase Transition in Magnetic Cantilever Coupled to a Bose Einstein Condensate

Aranya B. Bhattacherjee, Tobias Brandes

We propose a possibility of a phonon laser by coupling a Bose-Einstein condensate to a nanomechanical cantilever with a magnetic tip. Due to the magnetic coupling, atomic spin flip…
