The phase transition between gapped topological phases represents a class of
unconventional criticality beyond the Landau paradigm. However, recent research has …

By constructing an exactly solvable spin model, we investigate the critical behaviors of
transverse-field Ising chains interpolated with cluster interactions, which exhibit various …

Over the past few decades, tremendous efforts have been devoted to understanding self-
duality at the quantum critical point, which enlarges the global symmetry and constrains the …

In recent years, programmable Rydberg-atom arrays have been widely used to simulate
new quantum phases and phase transitions, generating great interest among theorists and …

Based on large-scale density matrix renormalization group techniques, we investigate the
critical behaviors of quantum three-state Potts chains with long-range interactions. Using …

We investigate the quantum criticality and universality in Aubry-André-Harper (AAH) model

We develop the perturbation theory of the fidelity susceptibility in biorthogonal bases for
arbitrary interacting non-Hermitian many-body systems with real eigenvalues. The quantum …

Decades of research have revealed a deep understanding of topological quantum matter
with protected edge modes. We report that even richer physics emerges when tuning …

The understanding of quantum phase transitions in disordered or quasicrystal media is a
central issue in condensed matter physics. In this paper we investigate localization …

The correlations, entanglement entropy, and fidelity susceptibility are calculated for a one-
dimensional spin-1/2 XXZ chain with anisotropic power-law long-range interactions by …
