Symmetry Algebras of Stringy Cosets
Dushyant Kumar, Menika Sharma
We find the symmetry algebras of cosets which are generalizations of the minimal-model cosets, of the specific form . We study…
A Framework for Non-linear Time Evolution and Field Theories on State-Dependent Geometries
Dushyant Kumar
We introduce a framework for non-linear time evolution in quantum mechanics as a natural non-linear generalization of the Schrodinger equation. Within our framework, we derive simp…
Conformal embeddings and higher-spin bulk duals
Dushyant Kumar, Menika Sharma
It is well-known that conformal embeddings can be used to construct non-diagonal modular invariants for affine lie algebras. This idea can be extended to construct infinite series…
On a Generalization of GKO Coset Construction of Conformal Field Theories
Dushyant Kumar
We introduce a generalization of Goddard-Kent-Olive (GKO) coset construction of two dimensional conformal field theories based on a choice of a scaled affine subalgebra $\hat{\math…
Two-dimensional Yang-Mills Theory on Recursive Infinite Genus Surfaces
Dushyant Kumar
The partition function of Euclidean Yang-Mills theory on two dimensional surfaces is given by the Migdal formula. It involves the area and topological characteristics of the surfac…
Weak Coupling Expansion of Yang-Mills Theory on Recursive Infinite Genus Surfaces
Debashis Ghoshal, Camillo Imbimbo, Dushyant Kumar
We analyze the partition function of two dimensional Yang-Mills theory on a family of surfaces of infinite genus. These surfaces have a recursive structure, which was used by one o…
