Logarithmic Operators and Hidden Continuous Symmetry in Critical Disordered Models
J. -S. Caux, Ian I. Kogan, A. M. Tsvelik
We study the model of (2 + 1)-dimensional relativistic fermions in a random non-Abelian gauge potential at criticality. The exact solution shows that the operator expansion contain…
Topologically Massive Gauge Theory with O(2) Symmetry
Ian I. Kogan, Kai-Ming Lee
We discuss the structure of the vacua in topologically massive gauge theory on a torus. Since has two connected components, there are four classical vacua. The differ…
Two Phases of Supersymmetric Gluodynamics
Ian I. Kogan, Mikhail Shifman
We argue that supersymmetric gluodynamics has two phases with equivalent infrared behavior, one of which is asymptotically free and another one is superstrongly coupled in the ultr…
ON GRAVITATIONAL DRESSING OF 2D FIELD THEORIES IN CHIRAL GAUGE
Adel Bilal, Ian. I. Kogan
After giving a pedagogical review of the chiral gauge approach to 2D gravity, with particular emphasis on the derivation of the gravitational Ward identities, we discuss in some de…
