Abstract: Programmable quantum simulators based on neutral atom arrays today offer powerful platforms for studying strongly correlated phases of quantum matter. Here, we employ the projective symmetry group framework to describe the symmetry fractionalization patterns in a topologically ordered $\mathbb{Z}_{2}$ quantum spin liquid (QSL) synthesized in such a Rydberg array on the ruby lattice. By systematically comparing the static structure factors of $\textit{all}$ possible mean-field $\textit{Ans\"atze}$ against density-matrix renormalization group calculations, we identify a promising candidate for the precise $\mathbb{Z}_{2}$ QSL realized microscopically. We also present detailed analyses of the dynamical structure factors as a reference for future experiments and showcase how these spin correlations can differentiate between varied QSL $\textit{Ans\"atze}$.

Complexity enriched dynamical phases for fermions on graphs [17.70942538295701]
We investigate entanglement and Krylov complexity for fermions on regular graphs. Our investigations unveil that while entanglement follows volume laws on both types of regular graphs with degree $d = 2$ and $d = 3$, the Krylov complexity exhibits distinctive behaviors. For interacting fermions, our theoretical analyses find the dimension scales as $Dsim 4Nalpha$ for regular graphs of $d = 2$ with $0.38leqalphaleq0.59$, whereas it scales as $Dsim 4N$ for $d = 3$.

Fractional disclination charge and discrete shift in the Hofstadter butterfly [15.3862808585761]
We numerically compute the discrete shift $mathscrS$ for the square lattice Hofstadter model of free fermions. We show that bands with the same Chern number may have different values of $mathscrS$, although odd and even Chern number bands always have half-integer and integer values of $mathscrS$ respectively.
