Interplay of dynamical and explicit chiral symmetry breaking effects on a quark
(2019-05-01)
The relative contributions of explicit and dynamical chiral symmetry breaking in QCD models of the quark-gap equation are studied in dependence of frequently employed Ansätze for the dressed interaction and quark-gluon ...
Spontaneous symmetry breaking in a spin-orbit-coupled f=2 spinor condensate
(2015-01-23)
We study the ground-state density profile of a spin-orbit-coupled f=2 spinor condensate in a quasi-one-dimensional trap. The Hamiltonian of the system is invariant under time reversal but not under parity. We identify ...
Perturbative breaking of the pseudospin symmetry in the relativistic harmonic oscillator

Symmetry breaking in the genetic code: Finite groups
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
We investigate the possibility of interpreting the degeneracy of the genetic code, i.e., the feature that different codons (base triplets) of DNA are transcribed into the same amino acid, as the result of a symmetry breaking ...
Magnetic effects on spontaneous symmetry breaking/restoration in a toroidal topology
(American Physical Society, 2013)
We study temperature and finite-size effects on the spontaneous symmetry breaking/restoration for a
scalar field model under the influence of an external magnetic field, at finite chemical potential.We use the
two-particle ...
Phase-separated symmetry-breaking vortex-lattice in a binary Bose-Einstein condensate
(2020-01-01)
We study spontaneous-symmetry-breaking circularly-asymmetric phase separation of vortex lattices in a rapidly rotating harmonically-trapped quasi-two-dimensional (quasi-2D) binary Bose-Einstein condensate (BEC) with repulsive ...
Quark clustering and chiral symmetry breaking in nuclear matter
(World Scientific Publ Co Pte Ltd, 2003-10-20)
Chiral symmetry breaking at finite baryon density is usually discussed in the context of quark matter, i.e. a system of deconfined quarks. Many systems like stable nuclei and neutron stars however have quarks confined ...
On chiral symmetry breaking in a constant magnetic field in higher dimension
(2000-10-19)
Chiral symmetry breaking in the Nambu-Jona-Lasinio model in a constant magnetic field is studied in spacetimes of dimension D > 4. It is shown that a constant magnetic field can be characterized by [D-1/2] parameters. For ...
Probing SU(2) symmetry breaking in the nucleon sea
(1997-05-29)
Investigation of invariant cross-sections for production of K*- and K*0, in the fragmentation region of the proton, in p - p and γ - p reactions, gives a direct and unambiguous probe to the symmetry breaking of the nucleon ...
