Kähler-Chern-Simons Theory And Symmetries Of Anti-Self-Dual Gauge Fields, V. Parameswaran Nair, Jeremy Schiff
Kähler-Chern-Simons Theory And Symmetries Of Anti-Self-Dual Gauge Fields, V. Parameswaran Nair, Jeremy Schiff
Publications and Research
Kähler-Chern-Simons theory, which was proposed as a generalization of ordinary Chern-Simons theory, is explored in more detail. The theory describes anti-self-dual in-stantons on a four-dimensional Kähler manifold. The phase space is the space of gauge potentials, whose symplectic reduction by the constraints of anti-self-duality leads to the moduli space of instantons. We show that infinitesimal Bäcklund transformations, previously related to "hidden symmetries" of instantons, are canonical transformations generated by the anti-self-duality constraints. The quantum wave functions naturally lead to a generalized Wess-Zumino-Witten action, which in turn has associated chiral current algebras. The dimensional reduction of the anti-self-duality equations leading to …
Relativistic Wave Equation For Anyons, R. Jackiw, V. Parameswaran Nair
Relativistic Wave Equation For Anyons, R. Jackiw, V. Parameswaran Nair
Publications and Research
Construction of one-particle states as unitary representations of the Poincare algebra in 2 + 1 dimensions shows that an anyon has one polarization state. However, for nonzero spin manifestly linear and covariant realizations of Lorentz transformations require more than one field component, and an infinite number is needed when the value of spin is not an integer or half-integer. We discuss the relation between these two aspects of Poincare symmetry. In particular, we construct a relativistic equation for anyons where the number of physical polarizations is reduced to one by virtue of a gauge symmetry or equivalent constraint.

A Kähler-Chern-Simons Theory And Quantization Of Instanton Moduli Spaces, V. P. Nair, Jeremy Schiff
A Kähler-Chern-Simons Theory And Quantization Of Instanton Moduli Spaces, V. P. Nair, Jeremy Schiff
Publications and Research
A five dimensional field theory is introduced which is an analogue of three dimensional Chern-Simons theory. The reduced phase space in the theory is a moduli phase of instantons in four dimensional Euclidean gauge theory, with a symplectic structure induced by the Donaldson u-map. Issues related to quantization are discussed.

Topological Gauge Theory And Twistors, V. Parameswaran Nair, Jeremy Schiff
Topological Gauge Theory And Twistors, V. Parameswaran Nair, Jeremy Schiff
Publications and Research
By use of harmonic superfields, Witten’s topological gauge theory is written as a field theory on a supertwistor space. Further, using the realisation of complex compactified Minkowski space as a quadric in CP5, we show that the theory has a simple formulation in terms of analytic superfields on super-CP5 × CP3 .
U(1) Chern-Simons Theory And C=1 Conformal Blocks, Michiel Bos, V. Parameswaran Nair
U(1) Chern-Simons Theory And C=1 Conformal Blocks, Michiel Bos, V. Parameswaran Nair
Publications and Research
The quantization of the U ( 1 ) Chern-Simons action in three dimensions is carried out in a coherent state representation. The wave functionals obtained are generating functionals for the current correlator blocks of two-dimensional c= 1 rational conformal field theories, explicitly realizing a connection found by Witten.
