三角晶格上含有冷极性分子的超固相

Supersolid phase with cold polar molecules on a triangular lattice

L. Pollet, J. D. Picon, H. P. Buechler, M. Troyer

摘要:

我们研究了一个系统的异质结分子的三角形晶格和分析的潜力,这个系统的实验实现的超固相。基态相图包括超流相、固相和超固相。在有限的温度和强相互作用,有一个额外的乳液区,与短程相互作用的类似模型。我们导出了超固态的最大临界温度$T_c$和相应的熵$S/N = 0.04(1)$,并找到了实现它的可行的实验条件。

英文摘要:

We study a system of heteronuclear molecules on a triangular lattice and analyze the potential of this system for the experimental realization of a supersolid phase. The ground state phase diagram contains superfluid, solid and supersolid phases. At finite temperatures and strong interactions there is an additional emulsion region, in contrast to similar models with short-range interactions. We derive the maximal critical temperature $T_c$ and the corresponding entropy $S/N = 0.04(1)$ for supersolidity and find feasible experimental conditions for its realization.
