Abelian and Non–Abelian Dualities in String Backgrounds
We present a brief discussion of recent work on duality symmetries in non–trivial string backgrounds. Duality is obtained from a gauged non–linear σ–model with vanishing gauge field strength. Standard results are reproduced for abelian gauge groups, whereas a new type of duality is identified for non–abelian gauge groups. Examples of duals of WZW models and 4–d black holes are given. String The...
متن کاملNon-Abelian Chern-Simons Quantum Mechanics and Non-Abelian Aharonov-Bohm Effect
We construct a classical action for a system of N point-like sources which carry SU(2) non-Abelian charges coupled to non-Abelian Chern-Simons gauge fields, and develop a quantum mechanics for them. Adopting the coherent state quantization and solving the Gauss’ constraint in an appropriately chosen gauge, we obtain a quantum mechanical Hamiltonian given in terms of the Knizhnik-Zamolodchikov c...
متن کامل0 Chern - Simons Reduction and Non - Abelian Fluid Mechanics ∗
We propose a non-Abelian generalization of the Clebsch parameterization for a vector in three dimensions. The construction is based on a group-theoretical reduction of the Chern-Simons form on a symmetric space. The formalism is then used to give a canonical (symplectic) discussion of non-Abelian fluid mechanics, analogous to the way the Abelian Clebsch parameterization allows a canonical descr...
متن کاملClassical and Quantum Mechanics of Non-Abelian Chern-Simons Particles
We investigate the classical and quantum properties of a system of SU(N) non-Abelian Chern-Simons (NACS) particles. After a brief introduction to the subject of NACS particles, we first discuss about the symplectic structure of various SU(N) coadjoint orbits which are the reduced phase space of SU(N) internal degrees of freedom or isospins. A complete Dirac’s constraint analysis is carried out ...
متن کاملNon-Abelian Conifold Transitions and N = 4 Dualities in Three Dimensions
We show how Higgs mechanism for non-abelian N = 2 gauge theories in four dimensions is geometrically realized in the context of type II strings as transitions among compactifications of Calabi-Yau threefolds. We use this result and T-duality of a further compacitification on a circle to derive N = 4, d = 3 dual field theories. This reduces dualities for N = 4 gauge systems in three dimensions t...
