Heavy cosmic strings
M. Donaire, A. Rajantie
We argue that cosmic strings with high winding numbers generally form in first-order gauge symmetry breaking phase transitions, and we demonstrate this using computer simulations.…
Phase Transitions in the Early Universe and Defect Formation
A. Rajantie
In the first one of these two lectures, I give an introductory review of phase transitions in finite temperature field theories. I highlight the differences between theories with g…
Defect formation in the early universe
A. Rajantie
Topological defects are common in many everyday systems. In general, they appear if a symmetry is broken at a rapid phase transition. In this article, I explain why it is believed…
Estimation of vortex density after superconducting film quench
T. W. B. Kibble, A. Rajantie
This paper addresses the problem of vortex formation during a rapid quench in a superconducting film. It builds on previous work showing that in a local gauge theory there are two…
Magnetic monopoles from gauge theory phase transitions
A. Rajantie
Thermal fluctuations of the gauge field lead to monopole formation at the grand unified phase transition in the early Universe, even if the transition is merely a smooth crossover.…
Numerical study of duality and universality in a frozen superconductor
T. Neuhaus, A. Rajantie, K. Rummukainen
The three-dimensional integer-valued lattice gauge theory, which is also known as a "frozen superconductor," can be obtained as a certain limit of the Ginzburg-Landau theory of sup…
