Symmetries in nature have fascinated mankind ever since the beginning of civilization, as they help us understanding nature’s most fundamental laws. A familiar example is rotational symmetry: the fact that physical phenomena do not depend on the direction they are observed from.
The symmetries something admits the more exotic and rich the associated mathematical structures become and therefore the more solvable the associated physical phenomena become.
In recent decades there has been a substantial effort to understand conformal symmetry: the invariance under coordinate transformations which preserve angles but not necessarily lengths. The field as a whole has come to be knowns as conformal field theory.
This PhD project is on the interface between pure mathematics and mathematical physics. It will study ways of detecting and classifying certain algebraic structures arising in this setting, in particular algebra objects in modular tensor categories obtained from representations of vertex operator algebras. These structures encode concepts from physics in elegant ways and interconnect a number of mathematical formalisations of physical theories such as r-spin topological field theories. Exploring these connections will form a vital part of the PhD project.
To achieve these aims, the student will develop a solid background in advanced algebra:
• representation theory,
• category theory,
• the relations between the various mathematical descriptions of conformal field theory.
The project will have a programming component which will give the student the opportunity to learn the Sage and Python programming languages.
Additionally, the student will get additional training on academic skills such as critical thinking and logical reasoning, scientific writing and communication, research independence, and collaboration. They will become part of an international network of researchers, and are expected to produce scientific output in the shape of publications, talks and conference posters.
The 3.5 year studentship includes UK/EU fees, stipend (amount for 2020/21 is £15285) and a research training grant to cover costs such as research consumables, training, conferences and travel. HOW TO APPLY
