The pressure-temperature phase diagram of the organic Mott insulator kappa-(ET)2Cu2(CN)3, a model system of the spin liquid on triangular lattice, has been investigated by 1H NMR and resistivity measurements. The spin-liquid phase is persistent before the Mott transition to the metal or superconducting phase under pressure. At the Mott transition, the spin fluctuations are rapidly suppressed an...
Applying a voltage difference between a conductor and a sessile droplet sitting on a thin dielectric film separating it from the conductor will cause the drop to spread. When the conductor is a good metal, the change of the drop’s contact angle due to the voltage is given the Young-Lippmann equation. Here we report experiments with lightly-doped, single crystal silicon as the conductive electro...
We discuss the main characteristics that must be satisfied by Josephson junctions for metrological applications and, specifically, in the development of voltage standards of new generation. Data reported in the literature for the most established technologies, like SNS (Superconductor-Normal conductor-Superconductor), SINIS (SuperconductorInsulator-Normal conductor-Insulator-Superconductor) and...
In [6], S. Bloch conjectures a formula for the Artin conductor of the l-adic etale cohomology of a regular model of a variety over a local field and proves it for a curve. The formula, which we call the conductor formula of Bloch, enables us to compute the conductor that measures the wild ramification by using the sheaf of differential 1-forms. In this paper, we prove the formula in arbitrary d...
We experimentally demonstrate the validity of nonequilibrium fluctuation relations by using a quantum coherent conductor. In equilibrium the fluctuation-dissipation relation leads to the correlation between current and current noise at the conductor, namely, the Johnson-Nyquist relation. When the conductor is voltage biased so that the nonlinear regime is entered, the fluctuation theorem has pr...
