Domain Walls and Vortices with Non-Symmetric Core
Minos Axenides, Leandros Perivolaropoulos
We review recent work on a new class of topological defects which possess a nonsymmetric core. They arise in scalar field theories with global symmetries, U(1) for domain walls and…

A New Statistic for the Detection of Long Strings in Microwave Background Maps
Leandros Perivolaropoulos
A new statistic is briefly reviewed, designed to detect isolated coherent step-like discontinuities produced by cosmic strings present at late times. As a background I superpose a…

A Statistic for the Detection of Long Strings in Microwave Background Maps
Leandros Perivolaropoulos
Using analytical methods and Monte Carlo simulations, we analyze a new statistic designed to detect isolated step-like discontinuities which are coherent over large areas of Cosmic…
