From QED3_3 to Self-Dual Multicriticality in the Fradkin-Shenker Model

This paper proposes a continuum QED3_3 description with emergent symmetries for the multicritical point in a staggered Fradkin-Shenker model, demonstrating how it connects to the original model and establishing a duality with the easy-plane CP1\mathbb{CP}^1 model that implies a deconfined quantum multicritical point separating a gapped Z2\mathbb{Z}_2 spin liquid from a Néel phase.

Imprints of UA(1)U_A(1) chiral anomaly and disorder in the Dirac eigenspectrum of QCD at finite temperature

This study utilizes lattice QCD simulations to analyze the Dirac eigenspectrum at finite temperature, revealing how intermediate level statistics and Thouless conductance serve as diagnostics for the interplay between chiral symmetry restoration and disorder-driven localization, particularly in the context of the effective restoration of the anomalous UA(1)U_A(1) symmetry.
