Integrability and conformal symmetry in higher dimensions: A model with exact hopfion solutions
(2002-11-11)
We use ideas on integrability in higher dimensions to define Lorentz invariant field theories with an infinite number of local conserved currents. The models considered have a two-dimensional target space. Requiring the ...
Unsuitable use of spin and pseudospin symmetries with a pseudoscalar Cornell potential
(Iop Publishing Ltd, 2014-09-01)
The concepts of spin and pseudospin symmetries has been used as mere rhetorics to decorate the pseudoscalar potential [Chin. Phys. B 22 090301 (2013)]. It is also pointed out that a more complete analysis of the bound ...

The index of symmetry of compact naturally reductive spaces
(Springer, 2014-08)
We introduce a geometric invariant that we call the index of symmetry, which measures how far is a Riemannian manifold from being a symmetric space. We compute, in a geometric way, the index of symmetry of compact naturally ...
Entanglement entropy and superselection sectors. Part I. Global symmetries
(Springer, 2020-02)
Some quantum field theories show, in a fundamental or an effective manner, an alternative between a loss of duality for algebras of operators corresponding to complementary regions, or a loss of additivity. In this latter ...

The index of symmetry of three-dimensional Lie groups with a left-invariant metric
(De Gruyter, 2018-10)
We determine the index of symmetry of 3-dimensional unimodular Lie groups with a left-invariant metric. In particular, we prove that every 3-dimensional unimodular Lie group admits a left-invariant metric with positive ...
