Proceedings to the Workshops ''What comes beyond the Standard model'' 2000,2001, VOLUME 1: Festschrift dedicated to the 60th birthday of Holger Bech Nielsen
N. S. Mankoc Borstnik, C. D. Froggatt, D. Lukman +15
The present volume is the collection of contributions by friends of Holger Bech Nielsen for his 60th birthday. Contents: 1.Unified internal space of spins and charges (N. Mankoc Bo…
Semitopological Q-Rings
Minos Axenides
Semitopological Vortices (Q-Rings) are identified to be classical soliton configurations whose stability is attributed to both topological and nontopological charges. We discuss so…
Core Phase Transitions for Embedded Topological Defects
M. Axenides, L. Perivolaropoulos
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 wal…
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…
Baryon Number Non-Conservation and the Topology of Gauge Fields
Minos Axenides, Andrei Johansen, Holger B. Nielsen +1
An introduction to the subject of baryon number non-conservation in the electroweak theory at high temperatures or energies is followed by a summary of our discovery of an infinite…
