Journal ArticleDOI
Toda Theory and W-Algebra from a Gauged WZNW Point of View
TL;DR: In this paper, a new formulation of Toda theories is proposed by showing that they can be regarded as certain gauged Wess-Zumino-Novikov-Witten (WZNW) models.
Journal ArticleDOI
On the observation of vacuum birefringence
TL;DR: In this paper, a high-intensity laser pulse is focused to ultra-relativistic intensity and polarizes the vacuum which then acts like a birefringent medium.
Journal ArticleDOI
Zeta Functions and the Casimir Energy
TL;DR: In this article, a finite definition for the Casimir energy of an arbitrary ultrastatic spacetime with or without boundaries is given, which is intimately related to, but not identical to, the one-loop effective energy.
Journal ArticleDOI
On Hamiltonian reductions of the Wess-Zumino-Novikov-Witten theories
TL;DR: In this article, the structure of Hamiltonian symmetry reductions of Wess-Zumino-Novikov-Witten (WZNW) theories by first class Kac-Moody (KM) constraints is analysed in detail.
Journal ArticleDOI
Liouville and Toda theories as conformally reduced WZNW theories
TL;DR: In this paper, it was shown that Liouville theory can be regarded as an SL(2, o) Wess-Zumino-Novikov-Witten theory with conformal invariant constraints.
