Charged lepton electric dipole moments with the localized leptons and the new Higgs doublet in the two Higgs doublet model
We study the lepton electric dipole moments in the split fermion scenario, in
the two Higgs doublet model, where the new Higgs scalars are localized around
the origin in the extra dimension, with the help of the localizer field. We
observe that the numerical value of the electron (muon, tau) electric dipole
moment is at the order of the magnitude of 10^{-31} (10^{-24}, 10^{-22}) (e-cm)
and this quantity is sensitive the new Higgs localization in the extra
dimension.Comment: 20 pages, 7 figure

Photonic spatial Bell-state analysis for robust quantum secure direct communication using quantum dot-cavity systems
Recently, experiments showed that the spatial-mode states of entangled
photons are more robust than their polarization-mode states in quantum
communications. Here we construct a complete and deterministic protocol for
analyzing the spatial Bell states using the interaction between a photon and an
electron spin in a charged quantum dot inside a one-side micropillar
microcavity. A quantum nondemolition detector (QND) for checking the parity of
a two-photon system can be constructed with the giant optical Faraday rotation
in this solid state system. With this parity-check QND, we present a complete
and deterministic proposal for the analysis of the four spatial-mode Bell
states. Moreover, we present a robust two-step quantum secure direct
communication protocol based on the spatial-mode Bell states and the photonic
spatial Bell-state analysis. Our analysis shows that our BSA proposal works in
both the strong and the weak coupling regimes if the side leakage and cavity
loss rate is small.Comment: 8 pages, 4 figure
