Ferromagnetic instability in PAAI in the sky
R. B. MacKenzie, M. B. Paranjape, U. A. Yajnik
We study an idealised plasma of fermions, coupled through an abelian gauge force , and which is asymmetric in that the masses of the oppositely charged species are greatly…
Gravitons in the Strong-Coupling Regime
Jorge Gamboa, Richard MacKenzie, Fernando Méndez
In the context of gravity in the strong-coupling regime, the propagation amplitude of gravity coupled to relativistic particles undergoing geodesic separation is calculated exactly…
Vacuum Decay Induced by False Skyrmions
Éric Dupuis, Mareike Haberichter, Richard MacKenzie +2
We consider the Skyrme model modified by the addition of mass terms which explicitly break chiral symmetry and pick out a specific point on the model's target space as the unique t…
Tunneling decay of false vortices with gravitation
Eric Dupuis, Yan Gobeil, Bum-Hoon Lee +5
We study the effect of vortices on the tunneling decay of a symmetry-breaking false vacuum in three spacetime dimensions with gravity. The scenario considered is one in which the i…
Tunneling decay of false domain walls: the silence of the lambs
Mareike Haberichter, Richard MacKenzie, M. B. Paranjape +1
We study the decay of "false" domain walls, which are metastable states of the quantum theory where the true vacuum is trapped inside the wall, with the false vacuum outside. We co…
Tunneling decay of false kinks
Éric Dupuis, Yan Gobeil, Richard MacKenzie +3
We consider the decay of "false kinks," that is, kinks formed in a scalar field theory with a pair of degenerate symmetry-breaking false vacua in 1+1 dimensions. The true vacuum is…
