TOPOLOGICALLY MASSIVE ABELIAN GAUGE THEORY

Vacuum Instability in Topologically Massive Gauge Theory

We find the critical charge for a topologically massive gauge theory for any gauge group, generalising our earlier result for SU(2). The relation between critical charges in TMGT, singular vectors in the WZNW model and logarithmic CFT is investigated.

Topologically Massive Gauge Theory with O ( 2 ) Symmetry

We discuss the structure of the vacua in O(2) topologically massive gauge theory on a torus. Since O(2) has two connected components, there are four classical vacua. The different vacua impose different boundary conditions on the gauge potentials. We also discuss the non-perturbative transitions between the vacua induced by vortices of the theory. 11.15.Ex, 11.15.Kc. ∗On leave of absence from I...

Conformal Orbifold Partition Functions from Topologically Massive Gauge Theory

We continue the development of the topological membrane approach to open and unoriented string theories. We study orbifolds of topologically massive gauge theory defined on the geometry [0, 1] × Σ, where Σ is a generic compact Riemann surface. The orbifold operations are constructed by gauging the discrete symmetries of the bulk three-dimensional field theory. Multi-loop bosonic string vacuum a...

Pseudoclassical model for topologically massive gauge fields

A pseudoclassical model for P ,T -invariant system of topologically massive U(1) gauge fields is proposed. The model demonstrates a nontrivial relationship between continuous and discrete symmetries and reveals a phenomenon of “classical quantization”. It allows one to identify SU(1,1) symmetry and S(2,1) supersymmetry as hidden symmetries of the corresponding quantum system. We show this P ,T ...
