Confinement at Weak Coupling
The free energy of U(N) and SU(N) gauge theory was recently found to be of order N to all orders of a perturbative expansion about a center-symmetric orbit of vanishing curvature. Here I consider extended models for which this expansion is perturbatively stable. The extreme case of an SU(2) gauge theory whose configuration space is restricted to center-symmetric orbits has recently been investi...
متن کاملPhase diagram of the extended Hubbard model at weak coupling.
The Hubbard model including nearest neighbor interaction is studied at T50 on a d-dimensional hypercubic lattice (d@1) close to half filling. For the model in d5` we derive the exact result that the ground state at weak coupling is phase separated. Results for lower dimensions are then derived in a 1/d expansion. To obtain these results we first consider possible second order transitions. One t...
متن کاملBFKL Pomeron at Weak Coupling
We consider correlators of N = 4 super Yang Mills of the form A ∼〈O1O2O 1O 2〉, where the operatorsO1 andO2 are scalar primaries. In particular, we analyze this correlator in the planar limit and in a Lorentzian regime corresponding to high energy interactions in AdS. The planar amplitude is dominated by a Regge pole whose nature varies as a function of the ’t Hooft coupling g. At large g, the p...
متن کاملAntiferromagnetism of the 2D Hubbard Model at Half Filling: Analytic Ground State at Weak Coupling
r n̂r↑n̂r↓. In Shf we study the many-body eigenstates of the kinetic energy with vanishing eigenvalue of the Hubbard repulsion (W = 0 states). In the Sz = 0 sector, this is a N times degenerate multiplet. From the singlet component one obtains the ground state of the Hubbard model for U = 0, which is unique in agreement with a theorem by Lieb. The wave function demonstrates an antiferromagnetic o...
متن کاملVortices and Confinement at weak coupling
We discuss the physical picture of thick vortices as the mechanism responsible for confinement at arbitrarily weak coupling in SU(2) gauge theory. By introducing appropriate variables on the lattice we distinguish between thin, thick and ‘hybrid’ vortices, the latter involving Z(2) monopole loop boundaries. We present numerical lattice simulation results that demonstrate that the full SU(2) str...
