Interplay between nuclear chiral and reflection symmetry breakings revealed by the lifetime measurements in 76Br

Physics Letters B, 2022
Nearly degenerate positive-parity doublet bands and several E1 transitions between positive- and negative-parity bands have been identified in 76Br. These experimental observations are interpreted as the coexistence of chirality and octupole correlations,

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.

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 ...

Confinement and Chiral Symmetry Breaking from an ensemble of interacting Instanton-dyons(monopoles) in SU(2) QCD

EPJ Web of Conferences, 2017
We show how the increase in the Instanton-dyon density can explain both Confinement and Chiral symmetry breaking. We simulate an ensemble of 64 interacting Instanton-dyons for 2 colors and 0 or 2 quark flavors.

Evolution of holographic Fermi arcs from a Mott insulator

Journal of High Energy Physics, 2018
We study fermions in asymptotically anti-de Sitter black hole spacetimes which interact via novel chiral symmetry-preserving interactions. Computing the dual fermion two-point correlator, we show that these bulk interactions anisotropically gap Fermi ...

Magnetic catalysis and the chiral condensate in holographic QCD

Journal of High Energy Physics, 2020
We investigate the effect of a non-zero magnetic field on the chiral condensate using a holographic QCD approach. We extend the model proposed by Iatrakis, Kiritsis and Paredes in [1] that realises chiral symmetry breaking dynamically from 5d tachyon ...

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 ...

Quarkyonic matter and chiral symmetry breaking [PDF]

Nuclear Physics A, 2009
The appearance of a new phase of QCD, Quarkyonic Matter in the limit of large number of colors is studied within Nambu-Jona-Lassinio effective chiral model coupled to the Polyakov loop. The interplay of this novel QCD phase with chiral symmetry restoration and color deconfinement is discussed.

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.

Chiral-symmetry breaking in dual QCD [PDF]

Physical Review D, 1988
In the context of the formulation of QCD with dual potentials, we show that chiral-symmetry breaking occurs only in the confined state. Therefore, the transition temperature, beyond which chiral symmetry is restored, is the same as the deconfinement temperature. To carry out the calculation, it is necessary to couple quarks to dual gluons.
