A bstract We perform three dimensional lattice simulation of the electroweak symmetry
breaking process through two-step vacuum-like phase transitions with one step being first …

We consider the formation of point and line topological defects (monopoles and strings) from
a general point of view by allowing the probability of formation of a defect to vary. To …

We propose a new mechanism to produce a meron-antimeron pair in a two dimensional
antiferromagnet with an ultrafast laser pulse via a thermal Schwinger mechanism. Unlike …

From the theory of topological defect formation proposed for the early Universe, the so-
called Kibble mechanism, it follows that the density correlation functions of defects and …

We extend and generalize the seminal work of Brandenberger, Huang and Zhang on the
formation of strings during chiral phase transitions1 and discuss the formation of Abelian …

A numerical method for the solution of the time-dependent Ginzburg-Landau equations is
detailed. The method is based on the popular technique of gauge invariant variables …

We describe a novel phenomenon in which vortices are produced due to resonant
oscillations of a scalar field which is driven by a periodically varying temperature T, with T …

In studying the formation of topological defects, it is conventional to assume the “geodesic
rule” which is equivalent to minimizing gradients of the order parameter. This assumption …

In these lectures, I review cosmological phase transitions and the topological aspects of
spontaneous symmetry breaking. I then discuss the formation of walls, strings and …

We study nonequilibrium evolution in a self-interacting quantum field theory invariant under
space translation only by using a canonical approach based on the recently developed …
