Numerical evidence for the existence of a novel magnetic condensation in Yang-Mills theory
نویسنده
چکیده
We present a first numerical evidence for the existence of a novel magnetic condensate proposed recently by one of the authors in SU(2) Yang-Mills theory. In our framework, the spontaneously generated color magnetic field identified with the Savvidy vacuum has the microscopic origin and is a consequence of the intrinsic dynamics of the Yang-Mills theory. It strongly suggests the Nielsen– Olesen instability of the Savvidy vacuum disappears and the stability is restored without the need of the Copenhagen vacuum. The implications to the FaddeevSkyrme model are also discussed. These results are obtained through the first implementation of the Cho–Faddeev–Niemi decomposition of the Yang-Mills field on a lattice.

Cho-Faddeev-Niemi decomposition of lattice Yang-Mills theory and evidence of a novel magnetic condensation
We present the first implementation of the Cho–Faddeev–Niemi decomposition of the SU(2) Yang-Mills field on a lattice. Our construction retains the color symmetry (global SU(2) gauge invariance) even after a new type of Maximally Abelian gauge, as explicitly demonstrated by numerical simulations. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercia...
متن کاملMagnetic Condensation, Abelian Dominance, and Instability of Savvidy Vacuum in Yang-mills Theory *
We propose a novel type of color magnetic condensation originating from magnetic monopoles so that it provides the mass of off-diagonal gluons in the Yang-Mills theory. This dynamical mass generation enables us to explain the infrared Abelian dominance and monopole dominance by way of a non-Abelian Stokes theorem, which supports the dual superconductivity picture of quark confinement. Moreover,...
متن کاملAbelian monopoles and center vortices in Yang-Mills plasma
Condensation of the Abelian monopoles and the center vortices leads to confinement of color in low temperature phase of Yang-Mills theory. We stress that these topological magnetic degrees of freedom are also very important in the deconfinement regime: at the point of the deconfinement phase transition both the monopoles and the vortices are released into the thermal vacuum contributing, in par...
متن کاملDual superconductivity , monopole condensation and confining string in low - energy Yang - Mills theory . Part
We show that the QCD vacuum (without dynamical quarks) is a dual supercon-ductor at least in the low-energy region in the sense that monopole condensation does really occur. In fact, we derive the dual Ginzburg-Landau theory (i.e., dual Abelian Higgs model) directly from the SU(2) Yang-Mills theory by adopting the maximal Abelian gauge. The dual superconductor can be on the border between type ...
متن کاملMagnetic condensation , Abelian dominance , and instability of Savvidy vacuum
We show that a certain type of color magnetic condensation originating from magnetic monopole configurations is sufficient to provide the mass for off-diagonal gluons in the SU(2) Yang-Mills theory under the Cho–Faddeev– Niemi decomposition. In fact, such magnetic condensation is shown to occur by calculating the effective potential within the BRST quantization. This enables us to explain the i...
