报告摘要:
In this talk, I will introduce a new type of quantum phase dubbed “quantum slush state”. By performing an unbiased large-scale quantum Monte Carlo simulation, we investigate a minimal model describing the facilitated excitation in Rydberg atom arrays, and find that the wavefunction of its ground state is composed of configurations with fractal branching structures. This state features a quasi-long-range order (correlation functions with algebraic decay) as well as a heterogeneous structure of liquid and glass mixture, thus is different from most well-established quantum phases of matter.
