Chiral Symmetry Breaking and Cooling in Lattice QCD [PDF]
, 1995 Chiral symmetry breaking is calculated as a function of cooling in quenched lattice QCD. A non-zero signal is found for the chiral condensate beyond one hundred cooling steps, suggesting that there is chiral symmetry breaking associated with instantons ...

Confinement, Chiral Symmetry Breaking and it's Restoration using Dual QCD Formalism
EPJ Web of Conferences, 2018 Utilizing the dual QCD model in term of magnetic symmetry structure of non- Abelian gauge theories, the dynamical chiral-symmetry breaking using Schwinger-Dyson equation has been investigated.

Non-Hermitian BCS-BEC crossover of Dirac fermions
Journal of High Energy Physics, 2021 We investigate chiral symmetry breaking in a model of Dirac fermions with a complexified coupling constant whose imaginary part represents dissipation.

Effective restoration of the U_A(1) symmetry with temperature and density [PDF]
, 2004 We investigate the full U(3)$\otimes$U(3) chiral symmetry restoration, at finite temperature and density, on the basis of a quark model which incorporates the most relevant properties of QCD in this context: explicit and spontaneous breaking of chiral ...

Ultrasensitive Chiral Spectroscopy by Dynamical Symmetry Breaking in High Harmonic Generation
Physical Review X, 2019 We propose and numerically demonstrate a new chiral spectroscopy method that is based on a universal system-independent mechanism of dynamical symmetry breaking in high harmonic generation (HHG).

A gravity dual of chiral symmetry breaking [PDF]
Fortschritte der Physik, 2004 AbstractWe establish a holographic description of chiral symmetry breaking for a particular confining large N non‐supersymmetric gauge theory with matter in the fundamental representation. The gravity dual of this theory is obtained by introducing a D7‐brane probe into a deformed Anti‐de Sitter background found by Constable and Myers.

Chiral symmetry restoration in excited hadrons, quantum fluctuations, and quasiclassics
, 2005 In this paper, we discuss the transition to the semiclassical regime in excited hadrons, and consequently, the restoration of chiral symmetry for these states.

Relating Quark Confinement and Chiral Symmetry Breaking in QCD [PDF]
, 2017 We study the relation between quark confinement and chiral symmetry breaking in QCD. Using lattice QCD formalism, we analytically express the various "confinement indicators", such as the Polyakov loop, its fluctuations, the Wilson loop, the inter-quark ...

Anomaly constraint on massless QCD and the role of Skyrmions in chiral symmetry breaking
Journal of High Energy Physics, 2018 We discuss consequences of the ’t Hooft anomaly matching condition for Quantum Chromodynamics (QCD) with massless fundamental quarks. We derive the new discrete ’t Hooft anomaly of massless QCD for generic numbers of color N c and flavor N f , and an ...

Chiral symmetry breaking in continuum QCD [PDF]
Physical Review D, 2015 We present a quantitative analysis of chiral symmetry breaking in two-flavour continuum QCD in the quenched limit. The theory is set-up at perturbative momenta, where asymptotic freedom leads to precise results. The evolution of QCD towards the hadronic phase is achieved by means of dynamical hadronisation in the non-perturbative functional ...
