Non-Hermitian BCS-BEC crossover of Dirac fermions

open access: yesJournal 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.

Aspects of Chiral Symmetry [PDF]

open access: yesInternational Journal of Modern Physics E, 1997
This article is an attempt to a pedagogical introduction and review into the elementary concepts of chiral symmetry in nuclear physics. Effective chiral models such as the linear and nonlinear sigma model will be discussed as well as the essential ideas of chiral perturbation theory.

Catalysis of dynamical chiral symmetry breaking by chiral chemical potential in Dirac semimetals [PDF]

open access: yesPhysical review B, 2016
In this paper we study the properties of media with chiral imbalance parameterized by chiral chemical potential. It is shown that depending on the strength of interaction between constituents in the media the chiral chemical potential either creates or ...

Symmetries and in-medium effects: Chiral symmetry breaking and modification of meson properties in a strongly interacting medium

open access: yesEPJ Web of Conferences, 2014
Chiral symmetry is a fundamental symmetry of Quantum Chromodynamics (QCD) in the limit of vanishing quark masses. In the hadronic sector chiral symmetry is broken; otherwise chiral partners - hadronic states with the same spin but opposite parity ...

ASPECTS OF CHIRAL SYMMETRY [PDF]

open access: yes, 2001
We give a pedagogical review of implications of chiral symmetry in QCD. First, we briefly discuss classical textbook subjects such as the axial anomaly, spontaneous breaking of the flavor-nonsinglet chiral symmetry, formation of light pseudo-Goldstone particles, and their effective interactions. Then we proceed to other issues.

Unbreaking chiral symmetry

open access: yesPhysical Review D, 2011
In Quantum Chromodynamics (QCD) the eigenmodes of the Dirac operator with small absolute eigenvalues have a close relationship to the dynamical breaking of the chiral symmetry. In a simulation with two dynamical quarks, we study the behavior of meson propagators when removing increasingly more of those modes in the valence sector, thus partially ...

CHIRAL SYMMETRIES IN NUCLEAR PHYSICS [PDF]

open access: yesHNPS Proceedings, 2000
In this report the theoretical concepts of a chirally symmetric meson field theory are reviewed and an overview of the most relevant applications in nuclear physics is given. This includes a unified description of the vacuum properties of hadrons, finite nuclei and hot, dense and strange nuclear matter in an extended chiral SU(3)_L x SU(3)_R σ-ω model.

Effects of rotation and boundaries on chiral symmetry breaking of relativistic fermions [PDF]

open access: yes, 2017
In order to avoid unphysical causality-violating effects any rigidly rotating system must be bounded in directions transverse to the axis of rotation. We demonstrate that this requirement implies substantial dependence of properties of relativistically ...
