Chiral Lattice Gauge Theories from Warped Domain Walls and Ginsparg-Wilson Fermions
Tanmoy Bhattacharya, Matthew R. Martin, Erich Poppitz
We propose a construction of a 2-dimensional lattice chiral gauge theory. The construction may be viewed as a particular limit of an infinite warped 3-dimensional theory. We also p…
Towards a chiral gauge theory by deconstruction in AdS5
Tanmoy Bhattacharya, Rajan Gupta, Matthew R. Martin +3
We describe an implementation of a deconstructed gauge theory with charged fermions defined on an interval in five dimensional AdS space. The four dimensional slices are Minkowski,…
Boundary Localized Symmetry Breaking and Topological Defects
R. Holman, Matthew R. Martin
We discuss the structure of topological defects in the context of extra dimensions where the symmetry breaking terms are localized. These defects develop structure in the extra dim…
The enhancement of inflaton loops in an alpha-vacuum
Hael Collins, Matthew R. Martin
While inflaton loops in the Euclidean vacuum generally have a negligible contribution to the power spectrum, loop effects can be substantially larger when the inflaton is in a non-…
The Fate of the Alpha-Vacuum
Hael Collins, R. Holman, Matthew R. Martin
de Sitter space-time has a one complex parameter family of invariant vacua for the theory of a free, massive scalar field. For most of these vacua, in an interacting scalar theory…
Radion Induced Baryogenesis
Matthew R. Martin
Recent work in two brane Randall-Sundrum models has shown that the radion can drive parametric amplification of particles on the TeV brane leading to a stage of cosmology similar t…
