具有无限程棋盘格相互作用的格子玻色子

Lattice bosons with infinite range checkerboard interactions

Bhuvanesh Sundar, Erich J. Mueller

摘要:

受Landig等人[Nature 532,476-479]实验的启发,我们考虑了光晶格中的二维玻色气体,该气体被捕获在单模超辐射法布里-珀罗腔中。该腔介导了原子间的无限程棋盘格相互作用,产生了莫特绝缘体、电荷密度波、超流和超固相之间的竞争。我们计算了这种玻色气体在均匀系统中的相图,并在谐波陷阱的存在。

英文摘要:

Motivated by experiments performed by Landig et al. [Nature 532, 476-479], we consider a two dimensional Bose gas in an optical lattice, trapped inside a single mode superradiant Fabry Perot cavity. The cavity mediates infinite range checkerboard interactions between the atoms, which produces competition between Mott insulator, charge density wave, superfluid and supersolid phases. We calculate the phase diagram of this Bose gas in a homogeneous system and in the presence of a harmonic trap.
