论文摘要
我们使用混合量子/经典模拟在三角晶格上研究远程相互作用的电子,而不是晶格库仑液的常规描述。我们在强相互作用极限中的结果表明,量子缺陷的出现和增殖控制了这种强烈沮丧的系统的低温动态,这至关重要地取决于电子结构的各向异性程度。目前的理论发现解释了在$θ$ -ET $ _2 $ x电荷订购材料中脱离平衡时观察到的现象学。在此设计的方法可以很容易地推广,以解决其他系统通过量子波动提高电荷挫败感的系统。
We study long-range interacting electrons on the triangular lattice using mixed quantum/classical simulations going beyond the usual classical descriptions of the lattice Coulomb fluid. Our results in the strong interaction limit indicate that the emergence and proliferation of quantum defects governs the low-temperature dynamics of this strongly frustrated system, in a way that crucially depends on the degree of anisotropy of the electronic structure. The present theoretical findings explain the phenomenology observed in the $θ$-ET$_2$X charge ordering materials as they fall out of equilibrium. The approach devised here can be easily generalized to address other systems where charge frustration is lifted by quantum fluctuations.
