Localization and Fractionalization in a Chain of Rotating Atomic Gases

Jianshi Zhao, Louis Rene Jacome, Craig Price, Nathan Gemelke

摘要:

我们描述了一系列轴向隧道耦合分数量子霍尔系统的相图和热力学性质实现了一系列的光偶极陷阱围绕他们的中心旋转。我们不仅展示了一个实验上可行的途径,可描述为一个Mott绝缘体的复合玻色子的状态,但也描述了在较高的隧道耦合强度的相干态的性质,并确定了一系列新的超流相丰富的行为。相图不仅直接揭示了少体系统的特征,包括复合粒子和空穴类激发及其相互作用的有效质量,而且链的涌现性质还揭示了由粒子编织和流体静力学响应的气体在导电相中的二维系统的绝热动力学之间的基本映射。

英文摘要:

We describe the phase diagram and thermodynamic properties of a chain of axially-tunnel-coupled fractional quantum Hall systems realized by rotating a series of optical dipole traps about their center. We demonstrate not only a experimentally feasible pathway to a state describable as a Mott-insulator of composite bosons, but also describe the nature of the coherent states at higher tunnel coupling strength, and identify a series of new superfluid phases with rich behavior. The phase diagram directly reveals not only characteristic features of the few-body systems, including the effective mass of composite particle- and hole-like excitations and their interactions, but emergent properties of the chain also reveal a fundamental mapping between the adiabatic dynamics of two dimensional systems governed by particle braiding and the hydrostatic response of the gas in the conducting phases.
