Superconducting String Texture
L. Perivolaropoulos, T. N. Tomaras
We present a detailed analytical and numerical study of a novel type of static, superconducting, classically stable string texture in a renormalizable topologically trivial massive…
Core Phase Structure of Cosmic Strings and Monopoles
M. Axenides, L. Perivolaropoulos, T. Tomaras
Global and local symmetries may or may not be restored inside topological defects depending upon the values of the parameters of the model. A detailed study of this parameter depen…
Formation of Vortices in First Order Phase Transitions
Alejandra Melfo, Leandros Perivolaropoulos
Using a toy model Lagrangian we investigate the formation of vortices in first order phase transitions. The evolution and interactions of vacuum bubbles are also studied using both…
On the Asymptotics of Nielsen-Olesen Vortices
Leandros Perivolaropoulos
We investigate analytically and numerically the asymptotic behavior of the Nielsen-Olesen vortex solutions and show that they approach their asymptotic values exponentially but wit…
Peculiar Velocities and Microwave Background Anisotropopies from Cosmic Strings
L. Perivolaropoulos, T. Vachaspati
Using an analytic model we show that the predictions of the cosmic string model for the peculiar velocities and the microwave background (MBR) anisotropy depend on similar combinat…
Nontopological Global Field Dynamics
Leandros Perivolaropoulos
We use arguments based on Derrick's theorem to show that the property of collapse which is the key feature of global texture appears in several field theory models with broken glob…
