3D scalar model as a 4D perfect conductor limit: dimensional reduction and variational boundary conditions
A. Edery, N. Graham, I. MacDonald
Under dimensional reduction, a system in D spacetime dimensions will not necessarily yield its D-1-dimensional analog version. Among other things, this result will depend on the bo…
Emergence of Oscillons in an Expanding Background
E. Farhi, N. Graham, A. H. Guth +3
We consider a (1+1) dimensional scalar field theory that supports oscillons, which are localized, oscillatory, stable solutions to nonlinear equations of motion. We study this theo…
Quantum stabilization of Z-strings, a status report on D=3+1 dimensions
O. Schroeder, N. Graham, M. Quandt +1
We investigate an extension to the phase shift formalism for calculating one-loop determinants. This extension is motivated by requirements of the computation of Z-string quantum e…
Numerical Simulation of an Electroweak Oscillon
N. Graham
Numerical simulations of the bosonic sector of the electroweak Standard Model in 3+1 dimensions have demonstrated the existence of an oscillon -- an extremely lo…
An Electroweak Oscillon
N. Graham
A recent study demonstrated the existence of oscillons -- extremely long-lived localized configurations that undergo regular oscillations in time -- in spontaneously broken SU(2) g…
