Homology in Abelian Lattice Models
Mark Rakowski, Siddhartha Sen
We study abelian lattice gauge theory defined on a simplicial complex with arbitrary topology. The use of dual objects allows one to reformulate the theory in terms of new dynamica…
Morse Theory and the Topology of Configuration Space
W. D. McGlinn, L. O'Raifeartaigh, S. Sen +1
The first and second homology groups are computed for configuration spaces of framed three-dimensional point particles with annihilation included, when up to two particles and an a…
QED in strong, finite-flux magnetic fields
M. P. Fry
Lower bounds are placed on the fermionic determinants of Euclidean quantum electrodynamics in two and four dimensions in the presence of a smooth, finite-flux, static, unidirection…
Phase and Scaling Properties of Determinants Arising in Topological Field Theories
David H. Adams, Siddhartha Sen
In topological field theories determinants of maps with negative as well as positive eigenvalues arise. We give a generalisation of the zeta-regularisation technique to derive expr…
