合成量子系统中相互作用拓扑相的实现和表征是一项艰巨的挑战。在这里,我们提出了一个Floquet协议来实现具有幂律衰减相互作用的反铁磁海森堡模型。基于分析和数值论证,我们证明了该模型具有从液体到价键固体的量子相变,该相变自发地打破了晶格平移对称,并使人联想到Majumdar-Ghosh态。通过测量完全二聚态的演化,可以动态地探测不同的相。此外,我们还引入了一种干涉协议来表征相互作用的多体系统的拓扑激励和体积拓扑不变量。
Realizing and characterizing interacting topological phases in synthetic quantum systems is a formidable challenge. Here, we propose a Floquet protocol to realize the antiferromagnetic Heisenberg model with power-law decaying interactions. Based on analytical and numerical arguments, we show that this model features a quantum phase transition from a liquid to a valence bond solid that spontaneously breaks lattice translational symmetry and is reminiscent of the Majumdar-Ghosh state. The different phases can be probed dynamically by measuring the evolution of a fully dimerized state. We moreover introduce an interferometric protocol to characterize the topological excitations and the bulk topological invariants of the interacting many-body system.
