Phase transitions in a non-perturbative regime can be studied by ab initio Lattice Field
Theory methods. The status and future research directions for LFT investigations of Quantum …

The many-body physics at quantum phase transitions shows a subtle interplay between
quantum and thermal fluctuations, emerging in the low-temperature limit. In this review, we …

The deconfined quantum critical point (DQCP) is an example of phase transitions beyond
the Landau symmetry-breaking paradigm that attracts wide interest. However, its nature has …

The deconfined quantum critical point (QCP), separating the Néel and valence bond solid
phases in a 2D antiferromagnet, was proposed as an example of (2+ 1) D criticality …

The deconfined quantum critical point (DQCP) represents a paradigm shift in quantum
matter studies, presenting a “beyond Landau” scenario for order-order transitions. Its …

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

We develop a nonequilibrium increment method to compute the Rényi entanglement
entropy and investigate its scaling behavior at the deconfined critical (DQC) point via large …

The fermion disorder operator has been shown to reveal the entanglement information in 1D
Luttinger liquids and 2D free and interacting Fermi and non-Fermi liquids emerging at …

Quantum spin liquids (QSLs) as novel phases of matter with long-range entanglement and
deconfined quantum critical points (DQCPs) as descriptions for unconventional phase …

We use the density matrix renormalization group method to calculate several energy
eigenvalues of the frustrated S= 1/2 square-lattice J 1-J 2 Heisenberg model on 2 L× L …
