Topology and Confinement In Light-Front QCD
In 1+1 dimensional compact QCD the zero modes of A give the theory a non-trivial topological structure. We examine the effects of these topological structures on the confining infrared structure of the theory. We show that the ground state wavefunction of the topological excitation smears the infrared behavior sufficiently to eliminate confinement for some matter currents. We review the work of...
متن کاملConfinement Physics and Topology in Qcd
Based on the dual-superconductor picture, we study the confinement physics in QCD in terms of the monopole in the maximally abelian (MA) gauge using the SU(2) lattice QCD. In the MA gauge, the off-diagonal gluon component is forced to be small, and hence microscopic abelian dominance on the link variable is observed in the lattice QCD for the whole region of β. ¿From the gluon-propagator analys...
متن کاملProving Nontrivial Topology of Pure Bismuth by Quantum Confinement.
The topology of pure Bi is controversial because of its very small (∼10 meV) band gap. Here we perform high-resolution angle-resolved photoelectron spectroscopy measurements systematically on 14-202 bilayer Bi films. Using high-quality films, we succeed in observing quantized bulk bands with energy separations down to ∼10 meV. Detailed analyses on the phase shift of the confined wave function...
متن کاملSu(2) Gluodynamics and Hp Σ-model Embedding: Scaling, Topology and Confinement
We investigate recently proposed HP 1 σ-model embedding method aimed to study the topology of SU(2) gauge fields. The HP 1 based topological charge is shown to be fairly compatible with various known definitions. We study the corresponding topological susceptibility and estimate its value in the continuum limit. The geometrical clarity of HP 1 approach allows to investigate non-perturbative asp...
متن کاملRing polymers as model bacterial chromosomes: confinement, chain topology, single chain statistics, and how they interact
Chromosomes in living cells are strongly confined but show a high level of spatial organization. Similarly, confined polymers display intriguing organizational and segregational properties. Here, we discuss how ring topology influences self-avoiding polymers confined in a cylindrical space, i.e. individual polymers as well as the way they interact. Our molecular dynamics simulations suggest tha...
