猝灭动力学中超流光畴的成核
Nucleation of superfluid-light domains in a quenched dynamics
摘要:
强关联效应出现在耦合共振器阵列中的光-物质相互作用中,例如原子-光子激发的莫特-绝缘体到超流相变。我们证明了一个有限大小的复杂耦合谐振器阵列的淬火动力学诱导一阶类似相变。后者是伴随着域成核,可用于操纵新兴的超流相的光子输运性质,这反过来又导致了经验的标度律。这种普遍的行为来自光-物质相互作用和阵列的拓扑结构。我们的结果在广泛的复杂体系结构的有效性可能会导致一个有前途的设备用于缩放量子模拟。
英文摘要:
Strong correlation effects emerge from light-matter interactions in coupled resonator arrays, such as the Mott-insulator to superfluid phase transition of atom-photon excitations. We demonstrate that the quenched dynamics of a finite-sized complex array of coupled resonators induces a first-order like phase transition. The latter is accompanied by domain nucleation that can be used to manipulate the photonic transport properties of the emerging superfluid phase; this in turn leads to an empirical scaling law. This universal behavior emerges from the light-matter interaction and the topology of the array. The validity of our results over a wide range of complex architectures might lead to to a promising device for use in scaled quantum simulations.
