调整超级眼镜的无序
Tuning the disorder of superglasses
摘要：
我们研究了超流性、玻璃态和磁性有序的硬核玻色子与随机干扰的相互作用。在经典极限下，该模型简化为具有铁磁键浓度$p$的$\pm J$ Edwards-Anderson伊辛模型，其在3D立方晶格上的临界浓度$p_c^{\rm cl}\sim 0.77$处主持玻璃-铁磁转变。我们的量子蒙特卡罗模拟结果表明，量子涨落稳定的超流性和玻璃秩序（“超玻璃”）的共存，并移动（超）玻璃-铁磁转变为$p_c> p_c^{\rm cl}$。相反，反铁磁秩序与超流性共存，形成超固体，并在较高的$p$下发生向玻璃相的转变。
英文摘要：
We study the interplay of superfluidity, glassy and magnetic orders of hardcore bosons with random frustrating interactions. In the classical limit, this model reduces to a $\pm J$ Edwards-Anderson Ising model with concentration $p$ of the ferromagnetic bonds, which hosts a glassy-ferromagnetic transition at a critical concentration $p_c^{\rm cl}\sim 0.77$ on a 3D cubic lattice. Our quantum Monte Carlo simulation results using the worm algorithm show that quantum fluctuations stabilize the coexistence of superfluidity and glassy order ("superglass"), and shift the (super)glassy-ferromagnetic transition to $p_c> p_c^{\rm cl}$. In contrast, antiferromagnetic order coexists with superfluidity to form a supersolid, and the transition to the glassy phase occurs at a higher $p$.
