Based on the simulation results, we also made an analytical model for the circuit yield of large-scale AQFP circuits. The yield analysis indicates that AQFP integrated circuits containing 1 million gates can be realized when the interconnect inductance is about 40 pH and the normalized standard deviation of the critical current is less than 1%

[en] We will investigate numerically a seesaw model with $A_4$ flavor symmetry to find allowed regions satisfying the current experimental neutrino oscillation data, then use them to predict physical consequences. Namely, the lightest active neutrino mass is of the order of $\mathcal{O}({10}^{-<!--\; ???\; -->2})$ eV. The effective neutrino mass $⟨<!--\; ???\; -->m⟩<!--\; ???\; -->$ associated with neutrinoless double beta decay is in the range $[0.002\mathrm{e}\mathrm{V},0.038\mathrm{e}\mathrm{V}]$ and $[0.048\mathrm{e}\mathrm{V},0.058\mathrm{e}\mathrm{V}]$, corresponding to the normal and the inverted hierarchy schemes, respectively. Other relations among relevant physical quantities are shown, so that they can be determined if some of them are confirmed experimentally. The recent data of the baryon asymmetry of the Universe (${\mathrm{\eta <!--\; ??\; -->}}_B$) can be explained via leptogenesis caused by the effect of the renormalization group evolution on the Dirac Yukawa couplings, provided the right-handed neutrino mass scale $M_0$ ranges from $\mathcal{O}({10}^8)$ GeV to $\mathcal{O}({10}^{12})$ GeV for $\tan <!--\; ???\; -->\mathrm{\beta <!--\; ??\; -->}=3$. This allowed $M_0$ range is different from the scale of $\mathcal{O}({10}^{13})$ GeV for other effects that also generate a consistent ${\mathrm{\eta <!--\; ??\; -->}}_B$ from leptogenesis. The branching ratio of the decay $\mathrm{\mu <!--\; ??\; -->}\to <!--\; ???\; -->e\mathrm{\gamma <!--\; ??\; -->}$ may reach future experimental sensitivity for very light values of $M_0$. Hence, it will be inconsistent with the $M_0$ range predicted from the ${\mathrm{\eta <!--\; ??\; -->}}_B$ data whenever this decay is detected experimentally.

[en] Polaritons in semiconductor microcavities are quasi-particles which result from the strong coupling between confined photons and electronic excitations. These bosons are 10⁹ times lighter than rubidium atoms, thus permitting BEC to occur at low density and high temperature. In this talk we present evidence for polariton condensation at around 20 K in a CdTe microcavity [Bose-Einstein condensation of exciton polaritons, Kasprzak et al., Nature 443, 409 (2006)]. We show also how the spontaneous coherence of the polariton condensate differs from the ideal case of non interacting bosons
