Cosmology of Bifundamental Fields
Tanmay Vachaspati
If a field theory contains gauged, non-Abelian, bi-fundamental fields i.e. fields that are charged under two separate non-Abelian gauge groups, the transition from a deconfined pha…
Formation of Non-Abelian Monopoles Connected by Strings
Yifung Ng, T. W. B. Kibble, Tanmay Vachaspati
We study the formation of monopoles and strings in a model where SU(3) is spontaneously broken to U(2)=[SU(2)\times U(1)]/\ZZ_2, and then to U(1). The first symmetry breaking gener…
Creating kinks from particles
Sourish Dutta, D. A. Steer, Tanmay Vachaspati
We study the creation of solitons from particles, using the model as a prototype. We consider the scattering of small, identical, wave pulses, that are equivalent to a seque…
Helical Magnetic Fields from Sphaleron Decay and Baryogenesis
Craig J. Copi, Francesc Ferrer, Tanmay Vachaspati +1
Many models of baryogenesis rely on anomalous particle physics processes to give baryon number violation. By numerically evolving the electroweak equations on a lattice, we show th…
Magnetic Fields in the Aftermath of Phase Transitions
Tanmay Vachaspati
The COSLAB effort has focussed on the formation of topological defects during phase transitions. Yet there is another potentially interesting signature of cosmological phase transi…
Cosmic Sparks from Superconducting Strings
Tanmay Vachaspati
We investigate cosmic sparks from cusps on superconducting cosmic strings in light of the recently discovered millisecond radio burst by Lorimer et al [1]. We find that the observe…
