论文摘要
在三角形晶格结构中,空间各向异性和挫败感可以通过包含复杂的,高度纠缠的物质状态的区域导致丰富的平衡相图。在这项工作中,我们研究了驱动的两型三角哈伯德模型,并从平衡中进化了这些状态,观察驾驶和初始状态之间的相互作用如何意外地关闭了粒子孔激发途径。对称性参数无法预测的这种限制决定了系统的瞬态动力学,从而导致可用的粒子孔自由度表现出均匀的远距离顺序。我们讨论了我们的结果对$ {\rmκ-(bedt-ttf)_ {2} cu [n(cn)_ {2}] br} br} $ molecules中的光诱导超导性的含义。
In triangular lattice structures, spatial anisotropy and frustration can lead to rich equilibrium phase diagrams with regions containing complex, highly entangled states of matter. In this work we study the driven two-rung triangular Hubbard model and evolve these states out of equilibrium, observing how the interplay between the driving and the initial state unexpectedly shuts down the particle-hole excitation pathway. This restriction, which symmetry arguments fail to predict, dictates the transient dynamics of the system, causing the available particle-hole degrees of freedom to manifest uniform long-range order. We discuss implications of our results for a recent experiment on photo-induced superconductivity in ${\rm κ- (BEDT-TTF)_{2}Cu[N(CN)_{2}]Br}$ molecules.
