Description:
Author(s): Miloslav Znojil For the two-mode and ( N − 1 ) − bosonic Bose-Hubbard quantum system a less usual phase transition controlled by the parameter ɛ representing the on-site energy difference is studied. In the literature the parameter is considered either real ( ɛ 〉 0 ) or purely imaginary (with, say, γ = Im ɛ 〉 0 ), so the pha... [Phys. Rev. A 98, 052102] Published Mon Nov 05, 2018
