Stability Constraints on Classical de Sitter Vacua
Stability Constraints Classical Sitter Vacua
2011/10/17
We present further no-go theorems for classical de Sitter vacua in Type II string theory, i.e., de Sitter constructions that do not invoke non-perturbative effects or explicit supersymmetry breaking l...
Linearized flavor-stability analysis of dense neutrino streams
Linearized flavor-stability analysis dense neutrino streams
2011/10/18
Neutrino-neutrino interactions in dense neutrino streams, like those emitted by a core-collapse supernova, can lead to self-induced neutrino flavor conversions. While this is a nonlinear phenomenon, t...
