Topological Defects from First Order Gauge Theory Phase Transitions
We investigate the mechanism by which topological defects form in first order phase transitions with a charged order parameter. We show how thick superconductor vortices and heavy cosmic strings form by trapping of magnetic flux. In an external magnetic field, intermediate objects such as strips and membranes of magnetic flux and chains of single winding defects are produced. At non-zero temper...
متن کاملFormation of topological defects in first order phase transitions.
c) Address after October 1st 1993: School of Mathematical and Physical Sciences, University of Sussex, Brighton BN1 9QH, U.K. We analyze the evolution of scalar and gauge fields during first order phase transitions and show how the Kibble mechanism1) for the formation of topological defects emerges from the underlying dynamics, paying particular attention to problems posed by gauge invariance w...
متن کاملMagnetic monopoles from gauge theory phase transitions
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. The dependence of the produced monopole density on various parameters is qualitatively different from theories with global symmetries, and the monopoles have a positive correlation at short distances. The number dens...
متن کاملQuasilumps from First Order Phase Transitions
We investigated the bubble collisions during the first order phase transitions. Numerical results indicate that within the certain range of parameters the collision of two bubbles leads to formation of separate relatively long-lived quasilumps configurations filled with scalar field oscillating around the true vacuum state. Energy is perfectly localized, and density is slightly pulsating around...
متن کاملCore Phase Transitions for Embedded Topological Defects
Vortices in superfluid 3He-B have been observed to undergo a core transition. We discuss the analog phenomenon in relativistic field theories which admit embedded global domain walls, vortices and monopoles with a core phase structure. They are present in scalar field theories with approximate global symmetries which are broken both spontaneously and in parts explicitly. For a particular range ...
