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…
An Oscillon in the SU(2) Gauged Higgs Model
E. Farhi, N. Graham, V. Khemani +2
We study classical dynamics in the spherical ansatz for the SU(2) gauge and Higgs fields of the electroweak Standard Model in the absence of fermions and the photon. With the Higgs…
Heavy Fermion Quantum Effects in SU(2)_L Gauge Theory
E. Farhi, N. Graham, R. L. Jaffe +2
We explore the effects of a heavy fermion doublet in a simplified version of the standard electroweak theory. We integrate out the doublet and compute the exact effective energy fu…
Searching for Quantum Solitons in a 3+1 Dimensional Chiral Yukawa Model
E. Farhi, N. Graham, R. L. Jaffe +1
We search for static solitons stabilized by heavy fermions in a 3+1 dimensional Yukawa model. We compute the renormalized energy functional, including the exact one-loop quantum co…
Finite Quantum Fluctuations About Static Field Configurations
Edward Farhi, Noah Graham, Peter E. Haagensen +1
We develop an unambiguous and practical method to calculate one-loop quantum corrections to the energies of classical time-independent field configurations in renormalizable field…
Correlation functions of the One-Dimensional Random Field Ising Model at Zero Temperature
Edward Farhi, Sam Gutmann
We consider the one-dimensional random field Ising model, where the spin-spin coupling, , is ferromagnetic and the external field is chosen to be with probability and $…
