Nonstandard Parafermions and String Compactification
Nonstandard Parafermions String Compactification High Energy Physics - Theory
2011/9/29
Abstract: Nonstandard parafermions are built and their central charges and dimensions are calculated. We then construct new N=2 superconformal field theories by tensoring the parafermions with a free ...
Space-Time Compactification, Non-Singular Black Holes, Wormholes and Braneworlds via Lightlike Branes
Space-Time Compactification Non-Singular Black Holes
2010/12/24
We describe a concise general scheme for constructing solutions of Einstein-Maxwell-Kalb-Ramond gravity-matter system in bulk space-time interacting self-consistently with one or more (widely separate...
We explore in detail the prospects of obtaining a four-dimensional de Sitter universe in classical supergravity models with warped and time-independent extra dimensions, presenting explicit cosmologic...
Sparticle Spectrum of Large Volume Compactification
Sparticle Spectrum Large Volume Compactification
2010/12/23
We examine the large volume compactification of Type IIB string theory or its F theory limit and the associated supersymmetry breakdown and soft terms. It is crucial to incorporate the loop-induced m...

Dynamical mass generation via space compactification in graphene
Dynamical generation via space compactification in graphene
2010/11/11
Fermions in a graphene sheet behave like massless particles. We show that by folding the sheet into a tube they acquire non-zero effective mass as they move along the tube axis. That is, changing the...
