Singularities of thermal correlators at strong coupling

Physical Interpretation of Certain Strong Coupling Singularities

Wilson loop correlators at strong coupling: from matrices to bubbling geometries

We compute at strong coupling the largeN correlation functions of supersymmetric Wilson loops in large representations of the gauge group with local operators of N = 4 super Yang-Mills. The gauge theory computation of these correlators is performed using matrix model techniques. We show that the strong coupling correlator of the Wilson loop with the stress tensor computed using the matrix model...

Matrix at strong coupling

We describe the strong coupling limit (g → ∞) for the Yang– Mills type matrix models. In this limit the dynamics of the model is reduced to one of the diagonal components which is characterized by a linearly confining potential. We also shortly discuss the case of the pure Yang–Mills model in more than one dimension.

Quantum solitons at strong coupling

We examine the effect of one loop quantum corrections on the formation of nontopological solitons in a strongly coupled scalar-fermionic Yukawa theory. The exact one fermion loop contribution is incorporated by using a nonlocal method to correct the local derivative expansion approximation (DE) of the effective action. As the Yukawa coupling is increased we find that the nonlocal corrections pl...

Diquark condensation at strong coupling

The possibility of diquark condensation at sufficiently large baryon chemical potential and zero temperature is analyzed in QCD at strong coupling. In agreement with other strong coupling analysis, it is found that a first order phase transition separates a low density phase with chiral symmetry spontaneously broken from a high density phase where chiral symmetry is restored. In none of the pha...
