Renormalization-Group Running Induced Cosmic Inflation
I. G. Marian, N. Defenu, U. D. Jentschura +2
As a contribution to a viable candidate for a standard model of cosmology, we here show that pre-inflationary quantum fluctuations can provide a scenario for the long-sought initia…
Lorentz Breaking and SU(2)_L x U(1)_Y Gauge Invariance for Neutrino Decays
U. D. Jentschura, I. Nandori, G. Somogyi
Conceivable Lorentz-violating effects in the neutrino sector remain a research area of great general interest, as they touch upon the very foundations on which the Standard Model a…
BKT-paired phase in coupled XY models
Giacomo Bighin, Nicolò Defenu, István Nándori +2
We study the effect of a linear tunneling coupling between 2D systems, each separately exhibiting the topological Berezinskii-Kosterlitz-Thouless (BKT) transition. In the uncoupled…
Neutrino Splitting for Lorentz-Violating Neutrinos: Detailed Analysis
G. Somogyi, I. Nandori, U. D. Jentschura
Lorentz-violating neutrino parameters have been severely constrained on the basis of astrophysical considerations. In the high-energy limit, one generally assumes a superluminal di…
