Quantum spin liquids are unique quantum states of matter predicted to arise in low-
dimensional, frustrated, and quantum magnetic systems. Compared with conventional …

We have carried out muon spin relaxation and rotation measurements on the newly
discovered kagome metal KV 3 Sb 5, and find a local field dominated by weak magnetic …

Non-stabilizerness–commonly known as magic–measures the extent to which a quantum
state deviates from stabilizer states and is a fundamental resource for achieving universal …

We study the Rényi entanglement entropy (EE) of the two-dimensional JQ model, the
emblematic quantum spin model of deconfined criticality at the phase transition between …

We develop a nonequilibrium increment method in quantum Monte Carlo simulations to
obtain the Rényi entanglement entropy of various quantum many-body systems with high …

The entanglement entropy is a unique probe to reveal universal features of strongly
interacting many-body systems. In two or more dimensions these features are subtle, and …

We introduce a many-body topological invariant, called the topological disorder parameter
(TDP), to characterize gapped quantum phases with global internal symmetry in 2+ 1 …

The subleading corner logarithmic corrections in entanglement entropy (EE) are crucial for
revealing the universal characteristics of quantum critical points (QCPs), but they are …

We introduce a quantum spin-1/2 model with many-body correlated Heisenberg-type
interactions on the two-dimensional square lattice, designed so that the system can host a …

The presence of competing interactions arising from geometry leads to frustration in
quantum spin models. As a consequence, the ground state of such systems often displays a …
