Decoherence inevitably happens when a quantum state is exposed to its environment,
which can affect quantum critical points (QCPs) in a nontrivial way. As was pointed out in the …

The “symmetric mass generation”(SMG) quantum phase transition discovered in recent
years has attracted great interest from both condensed matter and high energy theory …

Over the past two decades, the enigma of the deconfined quantum critical point (DQCP) has
attracted broad attention across the condensed matter, quantum field theory, and high …

We systematically investigate the finite size scaling behavior of the Rényi entanglement
entropy (EE) of several representative 2d quantum many-body systems between a …

There is no doubt that the information hidden in entanglement entropy (EE), for example, the
n th order Rényi EE, ie, S n A= 1 1− n ln Tr (ρ A n), where ρ A= Tr A¯ ρ is the reduced density …

Novel critical phenomena beyond the Landau-Ginzburg-Wilson paradigm have been long
sought after. Among many candidate scenarios, the deconfined quantum critical point …

Employing large-scale quantum Monte Carlo simulations, we systematically compute the
energy spectra of the two-dimensional (2D) spin-1/2 Heisenberg model with long-range …

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 …

Motivated by recent development of the concept of the disorder operator and its relation with
entanglement entropy in bosonic systems, here we show the disorder operator successfully …

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 …
