An Introduction to String Theory
James Bedford
These notes are based on lectures given by Michael Green during Part III of the Mathematics Tripos (the Certificate for Advanced Study in Mathematics) in the Spring of 2003. The co…
A note on Quantum Aspects of Multiple Membranes
James Bedford, David Berman
In this note we investigate quantum aspects of the newly proposed theory of multiple membranes put forward by Bagger and Lambert. In particular we analyse the possibility of a fini…
On perturbative field theory and twistor string theory
James Bedford
It is well-known that perturbative calculations in field theory can lead to far simpler answers than the Feynman diagram approach might suggest. In some cases scattering amplitudes…
Adding flavour to twistor strings
James Bedford, Constantinos Papageorgakis, Konstantinos Zoubos
Twistor string theory is known to describe a wide variety of field theories at tree-level and has proved extremely useful in making substantial progress in perturbative gauge theor…
Twistor Strings with Flavour
James Bedford, Constantinos Papageorgakis, Konstantinos Zoubos
We explore the tree-level description of a class of N=2 UV-finite SYM theories with fundamental flavour within a topological B-model twistor string framework. In particular, we ide…
Ruppeiner theory of black hole thermodynamics
Jan E Aman, James Bedford, Daniel Grumiller +2
The Ruppeiner metric as determined by the Hessian of the Gibbs surface provides a geometric description of thermodynamic systems in equilibrium. An interesting example is a black h…
