论文摘要
通过量子蒙特卡洛模拟研究了允许独立变化的晶格硬芯玻色子的相图，从排斥到有吸引力的近距离相互作用。我们观察到一个超氟相位，以及半填充的两个晶相，无论是棋盘还是条纹。就像在各向同性相互作用的情况下一样，未观察到超固体相。
The phase diagram of lattice hard core bosons with nearest-neighbor interactions allowed to vary independently, from repulsive to attractive, along different crystallographic directions, is studied by Quantum Monte Carlo simulations. We observe a superfluid phase, as well as two crystalline phases at half filling, either checkerboard or striped. Just like in the case of isotropic interactions, no supersolid phase is observed.
