Kinks and domain walls are the simplest kind of solitons and are invaluable for testing
various ideas and for learning about non-perturbative aspects of field theories. They are the …

A bstract Discrete symmetries play an important role in several extensions of the Standard
Model (SM) of particle physics. For instance, in order to avoid flavor changing neutral …

Young children with autism spectrum disorder vary greatly in their social and communication
skills, from non-verbal and difficult to engage socially, to using some sentences and showing …

An SU (5) grand unification scheme for effective 3+ 1-dimensional fields dynamically
localized on a domain-wall brane is constructed. This is achieved through the confluence of …

Interactions of different types of topological defects can play an important role in the
aftermath of a phase transition. We study interactions of fundamental magnetic monopoles …

We study kink or domain wall solutions in O (10) Higgs models in the context of the “clash of
symmetries” mechanism developed by Davidson, Toner, Volkas and Wali and …

We construct domain-wall brane models based on the grand-unification group SO (10),
generalizing the SU (5) model of Davies, George, and Volkas. Motivated by the Dvali …

We construct lattices with alternating kinks and antikinks. The lattice is shown to be stable in
certain models. We consider the forces between kinks and antikinks and find that the lattice …

We study the formation of domain walls in a phase transition in which an S 5× Z 2 symmetry
is spontaneously broken to S 3× S 2. In one compact spatial dimension we observe the …

The idea of quark-lepton universality at high energies has been introduced as a natural
extension to the standard model. This is achieved by endowing leptons with new degrees of …
