Instanton Induced Large N Phase Transitions in Two and Four Dimensional QCD
نویسنده
چکیده
The 1/N expansion of the weak coupling phase of two-dimensional QCD on a sphere is constructed. It is demonstrated that the phase transition from the weak to the strong coupling phase is induced by instantons. A double scaling limit of the theory at the point of the phase transition is constructed, the value of string susceptibility is determined to be γstr = −1. The possibility of instanton induced large N phase transitions in four dimensional QCD is explored. March 1994

Localization on the D - brane , two - dimensional gauge theory and matrix models
We consider the effective topological field theory on Euclidean D-strings wrapping on a 2cycle in the internal space. We evaluate the vev of a suitable operator corresponding to the chemical potential of vortices bounded to the D-strings, and find that it reduces to the partition function of generalized two-dimensional Yang-Mills theory as a result of localization. We argue that the partition f...

متن کاملMulti-Instanton Effect in Two Dimensional QCD
We analyze multi-instanton sector in two dimensional U(N) Yang-Mills theory on a sphere. We obtain a contour intregral representation of the multiinstanton amplitude and find “neutral” configurations of the even number instantons are dominant in the large N limit. Using this representation, we calculate the 1,2,3,4 bodies interactions and the free energies for N = 3, 4, 5 numerically and find t...
متن کاملNeutral Multi-Instanton as a Bridge from Weak to Strong Coupling phase in Two Dimensional QCD
Using a contour integral representation we analyze the multi-instanton sector in two dimensional U(N) Yang-Mills theory on a sphere and argue the role of multi-instanton in the large N phase transition. In the strong coupling region at the large N , we encounter “singular saddle point”. Because of this situation, “neutral” configurations of the multi-instanton are dominant in this region. Based...
متن کاملPhase transitions and mass generation in 2+1 dimensions.
The possibility that the epsilon expansion can predict the order of phase transitions in three dimensional field theories is examined. For a Hermitean matrix-valued order parameter, the epsilon expansion predicts fluctuation induced first order phase transitions. We analyze two 2+1-dimensional quantum field theories which exhibit spontaneous symmetry breaking and have martix order parameters. U...
