Topologically non–trivial chiral transformations: The chiral invariant elimination of the axial vector meson†

The role of chiral transformations in effective theories modeling Quantum Chromo Dynamics is reviewed. In the context of the Nambu–Jona–Lasinio model the hidden gauge and massive Yang–Mills approaches to vector mesons are demonstrated to be linked by a special chiral transformation which removes the chiral field from the scalar–pseudoscalar sector. The chirally rotated axial vector meson field ...

Topologically non-trivial quantum layers

Given a complete non-compact surface Σ embedded in R, we consider the Dirichlet Laplacian in the layer Ω that is defined as a tubular neighbourhood of constant width about Σ. Using an intrinsic approach to the geometry of Ω, we generalise the spectral results of the original paper [1] by Duclos et al. to the situation when Σ does not possess poles. This enables us to consider topologically more...

Topologically Trivial Legendrian Knots

This paper deals with topologically trivial Legendrian knots in tight and overtwisted contact 3-manifolds. The first parts (Sections 1-3) contain a thorough exposition of the proof of the classification of topologically trivial Legendrian knots (i.e. Legendrian knots bounding embedded 2-disks) in tight contact 3-manifolds (Theorem 1.7), and, in particular, in the standard contact S. These parts...

Fermi-Bose Cancellation in Topologically Non-Trivial Backgrounds

We show in a model-independent way that, in the background of a topological soliton or instanton that saturates a Bogomol’nyi bound, the fermion and boson excitation spectra of non-zero modes cancel at the one-loop level. This generalizes D’Adda and DiVecchia’s result for some specific instanton models. Our method also establishes, again in a modelindependent way, the generality of the connecti...

Topologically non-trivial configurations in 3-dimensional Yang-Mills theory

Monopoles are expected to play an important role in confining quarks in QCD. In lattice simulations, one usually looks for U(1) monopoles by fixing an Abelian gauge [1]. However it is important to have a gauge invariant way of detecting monopoles in non-Abelian gauge theories. In a recent paper [2] Anishetty, Majumdar and Sharatchandra have given a criterion for characterizing topologically non...
