Topological Gauge Theory And Twistors, V. Parameswaran Nair, Jeremy Schiff Jul 1989

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 Jun 1989

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.

Theoretical Studies Of The Energies And Geometries Of Strained Hydrocarbons, Mitchell Alan Miller Jan 1989

Theoretical Studies Of The Energies And Geometries Of Strained Hydrocarbons, Mitchell Alan Miller

Dissertations, Theses, and Capstone Projects

Theoretical models are used to explore problems of interest to organic chemists in four projects. The first three apply existing methodologies to investigate a series of strained cyclic hydrocarbon molecules; the fourth develops methodology.

Project I. Semiempirical calculations have been performed on a variety of hydrocarbons composed of fused cyclobutane rings using the MNDO, AM1 and MM2 methods. The systems studied include linearly concatenated cyclobutanes (ladderanes), cyclic structures (prismanes) and two 'star-shaped' C24H24 hydrocarbons, helvetane and israelane. The results reported include optimized geometries, heats of formation and vibrational frequencies. The performance of the theoretical models is evaluated …
