Ray-Wave Duality of Electromagnetic Fields: A Feynman Path integral Approach to Classical Vectorial Imaging
James Babington
We consider how vectorial aspects (polarization) of light propagation can be implemented, and its origin, within a Feynman path integral approach. A key part of this scheme is in g…
Graphene membranes and the Dirac-Born-Infeld action
James Babington
We propose the use of the Dirac-Born-Infeld action in the phenomenological description of graphene sheet dynamics and interactions. Both the electronic properties of the Dirac ferm…
Universal scaling laws for dispersion interactions
Stefan Yoshi Buhmann, Stefan Scheel, James Babington
We study the scaling behaviour of dispersion potentials and forces under very general conditions. We prove that a rescaling of an arbitrary geometric arrangement by a factor a chan…
Casimir forces between spheres
James Babington
We discuss the calculation of Casimir forces between a collection of -dielectric spheres. This is done by evaluating directly the force on a sphere constructed from a stress ten…
Casimir forces between spheres and loop integrals
James Babington
A summary of recent calculations of Casimir forces between a collection of -dielectric spheres is presented. This is done by evaluating directly the force on a sphere constructe…
Casimir forces from a loop integral formulation
James Babington
We reformulate the Casimir force in the presence of a non-trivial background. The force may be written in terms of loop variables, the loop being a curve around the scattering site…
Casimir Forces in Multi-Sphere Configurations
James Babington, Stefan Scheel
We calculate the Casimir force on an isolated dielectric sphere in an ensemble of spheres due to multiple mutual interactions of the collection of spheres. In particular we con…
Space-time dependent couplings in N=1 SUSY gauge theories: Anomalies and Central Functions
James Babington, Johanna Erdmenger
We consider N=1 supersymmetric gauge theories in which the couplings are allowed to be space-time dependent functions. Both the gauge and the superpotential couplings become chiral…
A Gravity Dual of Chiral Symmetry Breaking
J. Babington, J. Erdmenger, N. Evans +2
We establish a holographic description of chiral symmetry breaking for a particular confining large N non-supersymmetric gauge theory with matter in the fundamental representation.…
A Stable Supergravity Dual of Non-supersymmetric Glue
James Babington, David E. Crooks, Nick Evans
We study non-supersymmetric fermion mass and condensate deformations of the AdS/CFT Correspondence. The 5 dimensional supergravity flows are lifted to a complete and remarkably sim…
A Non-supersymmetric Deformation of the AdS/CFT Correspondence
James Babington, David E. Crooks, Nick Evans
We deform the AdS/CFT Correspondence by the inclusion of a non-supersymmetric scalar mass operator. We discuss the behaviour of the dual 5 dimensional supergravity field then lift…
Field Theory Operator Encoding in N=2 Geometries
James Babington, Nick Evans
We investigate supergravity solutions describing D5 branes wrapped on a two cycle which are dual to N=2 super Yang Mills theory. Brane probing these solutions allows the moduli spa…
Secrets of the Metric In N=4 and N=2* Geometries
James Babington, Nick Evans, James Hockings
The metric of the gravity dual of a field theory should contain precisely the same information as the field theory. We discuss this connection in the N=4 theory where a scalar vev…
