Duality refers to two equivalent descriptions of the same theory from different points of view.
Recently there has been tremendous progress in formulating and understanding possible …

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

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

Recently, significant progress has been made in (2+ 1)-dimensional conformal field theories
without supersymmetry. In particular, it was realized that different Lagrangians may be …

Continuous quantum phase transitions beyond the conventional paradigm of fluctuations of
a symmetry-breaking order parameter are challenging for theory. These phase transitions …

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 …

Deconfined quantum critical points govern continuous quantum phase transitions at which
fractionalized (deconfined) degrees of freedom emerge. Here we study dynamical …

We investigate the ground state phase diagram of an extended Hubbard model with a π-flux
hop** term at half filling on a square lattice, with unbiased large-scale auxiliary-field …

We investigate approximate emergent non-Abelian symmetry in a class of weakly first-order
'deconfined'phase transitions using Monte Carlo simulations and a renormalization group …
