Predicting leptonic CP violation in the light of Daya Bay result

In the light of the recent Daya Bay result the reactor angle is about 9 degrees, we reconsider the model presented in arXiv:1005.3482 showing that, when all neutrino oscillation parameters are taken at their best fit values of Schwetz et al and the reactor angle to be the central value of Daya Bay, the predicted value of the CP phase is approximately 45 degrees.Comment: 4 pages, 2 figures, update of arXiv:1005.348

Neutrino mixing matrices with relatively large θ13\theta_{13} and with texture one-zero

The recent T2K, MINOS and Double Chooz oscillation data hint a relatively large $\theta_{13}$, which can be accommodated by some general modification of the Tribimaximal/Bimaximal/Democratic mixing matrices. Using such matrices we analyze several Majorana mass matrices with texture one-zero and show whether they satisfy normal or inverted mass hierarchy and phenomenologically viable or not.Comment: 16 pages, 3 figures, minor modification in the text, version to appear in EPJ

An external ac bias induced expansion of dynamic voltage bands in a weakly coupled GaAs/AlAs superlattice

In the intermediate temperature region, an external ac bias induced expansion of dynamic voltage band (DVB) is investigated experimentally in a weakly coupled GaAs/AlAs superlattice. The observed results are explained based on an analysis of general nonlinear dynamics. It suggests that the effect of an external ac bias is to tighten the unstable limit cycle onto the stable fixed point. Beyond a certain critical value, the stable limit cycle is the only stable solution of the system resulting in the observation of self-sustained current oscillation. © 2005 American Institute of Physics
