Macroscopic quantum tunneling of the Bose-Einstein condensate trapped in cylindrically symmetric potential
Yukinori Yasui, Takayuki Takaai, Takayoshi Ootsuka
We investigate the macroscopic quantum tunneling of the attractive Bose-Einstein condensate. Within the effective Lagrangian framework, we find bounce solutions and explicitly calc…
