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 …

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 …

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 …

The two-dimensional Q-state Potts model with real couplings has a first-order transition for
Q> 4. We study a loop-model realization in which Q is a continuous parameter. This model …

Conformal symmetry, emerging at critical points, can be lost when renormalization group
fixed points collide. Recently, it was proposed that after collisions, real fixed points transition …

We suggest the possibility that the two-dimensional SU (2) k Wess-Zumino-Witten (WZW)
theory, which has global SO (4) symmetry, can be continued to 2+ ε dimensions by enlarging …

The deconfined quantum critical point (DQCP)--the enigmatic incarnation of the quantum
phase transition beyond the Landau-Ginzburg-Wilson paradigm of symmetries and their …

We report a quantum Monte Carlo study of the phase transition between antiferromagnetic
and valence-bond solid ground states in the square-lattice S= 1/2 J–Q model. The critical …

A quantum spin impurity coupled to a gapless free field (the Bose-Kondo model) can be
represented as a (0+ 1)-dimensional field theory with long-range-in-time interactions that …

Non-Hermitian physics in open quantum many-body systems provides novel opportunities
for the discovery of exotic quantum phenomena unexpected in Hermitian systems. A …
