چکیده
We discuss a possibility of detecting a coherent photon pair emission and related radiative neutrino pair emission from excited atoms. It is shown that atoms of lambdaand ladder-type three level system placed in a pencil-like cylinder give a back to back emission of two photons of equal energy ∆/2, sharply peaked with a width ∝ 1/( target size) and well collimated along the cylinder axis. This process has a measurable rate ∝ (target number density) 2× target volume, while a broader spectral feature of one-photon distribution

We study the behaviour of charge oscillations in Superconducting Cooper Pair Boxes weakly interacting with an environment. We found that, due to the noise and dissipation induced by the environment, the stability properties of these nanodevices differ according to whether the charge oscillations are interpreted as an effect of macroscopic quantum coherence, or semiclassically in terms of the Gr...

Dark matter is usually distinguished from ordinary matter by an odd-even parity, i.e. the discrete symmetry Z 2. The new idea of Z 3 dark matter is proposed with a special application to generating radiative Majorana neutrino masses in two-loop order.

The Adler sum rule states that the integral over energy of a difference of neutrino-nucleon and antineutrino-nucleon structure functions is a constant, independent of the four-momentum transfer squared. This constancy is a consequence of the local commutation relations of the time components of the hadronic weak current, which follow from the underlying quark structure of the standard model.

We consider a model based on A4 ⋉ (Ze ×Zμ ×Zτ ) flavor symmetry for TriBimaximal lepton mixing with two scalar A4-triplets whose vacuum expectation values have the same alignment. Neutrino masses are generated through effective dimension five Weinberg operators. Charged leptons mass hierarchies are generated with an additional Froggatt-Nielsen U(1)F flavor symmetry under which right-handed lept...
