Numerical shadow and geometry of quantum states
Charles F. Dunkl, Piotr Gawron, John A. Holbrook +3
The totality of normalised density matrices of order N forms a convex set Q_N in R^(N^2-1). Working with the flat geometry induced by the Hilbert-Schmidt distance we consider image…
Top quark asymmetry from a non-Abelian horizontal symmetry
Sunghoon Jung, Aaron Pierce, James D. Wells
Motivated by the persistence of a large measured top quark forward-backward asymmetry at the Tevatron, we examine a model of non-Abelian flavor gauge symmetry. The exchange of the…
Time evolution of the QED vacuum in a uniform electric Field: Complete analytic solution by spinorial decomposition
Iwo Bialynicki-Birula, Łukasz Rudnicki
Exact analytical solutions are presented for the time evolution of the density of pairs produced in the QED vacuum by a time-independent, uniform electric field. The mathematical t…
Heating up the Baryonic Branch with U-duality: a unified picture of conifold black holes
Elena Caceres, Carlos Nunez, Leopoldo A. Pando Zayas
We study different aspects of a U-duality recently presented by Maldacena and Martelli and apply it to non-extremal backgrounds. In particular, starting from new non-extremal wrapp…
The Spectrum of Excitations of Holographic Wilson Loops
Alberto Faraggi, Leopoldo A. Pando Zayas
In the holographic framework, a half BPS Wilson loop in supersymmetric Yang-Mills in the fundamental, symmetric or antisymmetric representation of SU(N), is best descr…
