Article Description

We study the Bose–Einstein condensation in a tight-binding model with a hopping rate enhanced only on a surface. We show that this model exhibits two different critical phenomena depending on whether the hopping rate on the surface t exceeds the critical value 5t / 4, where t is the hopping rate in the bulk. For t/ t< 5 / 4 , normal Bose–Einstein condensation occurs, while the Bose–Einstein condensation for t/ t≥ 5 / 4 is characterized by the spatial localization of the macroscopic number of particles at the surface. By exactly calculating the surface free energy, we show that for t/ t< 5 / 4 , the singularity of the surface free energy stems from diverging the correlation length in the bulk, while for t/ t≥ 5 / 4 , it is induced by the coupling effects between the bulk and surface.
