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 ...
Comment on "spontaneous breaking of permutation symmetry in pseudo-Hermitian quantum mechanics"
(American Physical Society, 2017-10)
Li and Miao [Phys. Rev. A 85, 042110 (2012)PLRAAN1050-294710.1103/PhysRevA.85.042110] proposed a non-Hermitian Hamiltonian that is neither Hermitian nor PT symmetric but exhibits real eigenvalues for some values of the ...
Dynamical Symmetries, Super-coherent States and Noncommutative Structures: Categorical and Geometrical Quantization Analysis
(Springer, 2018-04)
The relation between fundamental spacetime structures and dynamical symmetries are treated beyond the geometrical and topological viewpoint. To this end analyze, taking into account the concept of categories and quasi ...
Spin and pseudospin symmetries in the antinucleon spectrum of nuclei
(2010-06-28)
Spin and pseudospin symmetries in the spectra of nucleons and antinucleons are studied in a relativistic mean-field theory with scalar and vector Woods-Saxon potentials, in which the strength of the latter is allowed to ...
General spin and pseudospin symmetries of the Dirac equation
(Amer Physical Soc, 2015-12-31)
In the 1970s Smith and Tassie [G. B. Smith and L. J. Tassie, Ann. Phys. (NY) 65, 352 (1971)] and Bell and Ruegg [J. S. Bell and H. Ruegg, Nucl. Phys. B 98, 151 (1975); 104, 546 (1976)] independently found SU(2) symmetries ...

Some general aspects of thin-shell wormholes with cylindrical symmetry
(American Physical Society, 2010-04)
In this article we study a general class of nonrotating thin-shell wormholes with cylindrical symmetry. We consider two physically sound definitions of the flare-out condition and we show that the less restrictive one ...
Naturally light invisible axion in models with large local discrete symmetries
(American Physical Soc, 2003-05-01)
We show that by introducing appropriate local Z(N)(Ngreater than or equal to13) symmetries in electroweak models it is possible to implement an automatic Peccei-Quinn symmetry, at the same time keeping the axion protected ...
