    Imaging quantum fluctuations near criticality

    A quantum phase transition (QPT) occurs between two competing phases of matter at zero temperature, driven by quantum fluctuations. Although the presence of these fluctuations is well established, they have no...

    Superconductor–Insulator Transition in NbTiN Films

    Experimental results indicating a direct disorder-induced superconductor–insulator transition in NbTiN thin films have been reported. It has been shown that an increase in the resistance per square in the norm...

    Nonequilibrium transport near the superconducting transition in TiN films

    The linear and nonlinear conductions of titanium nitride films with the thickness d ≤ 10 nm have been studied experimentally in the region of superconducting transitions. It has been shown that the inclusion of a...

    Hyperactivated resistance in TiN films on the insulating side of the disorder-driven superconductor-insulator transition

    We investigate the insulating phase that forms in a titanium nitride film in a close vicinity of the disorder-driven superconductor-insulator transition. In zero magnetic field the temperature dependence of th...

    Anomalous behavior near T c and synchronization of Andreev reflection in two-dimensional arrays of SNS junctions

    The temperature dependences of resistance and the current-voltage characteristics of two-dimensional arrays of superconductor-normal metal-superconductor (SNS) junctions have been measured at low temperatures....

    Superconductivity on the localization threshold and magnetic-field-tuned superconductor-insulator transition in TiN films

    Temperature-and magnetic-field-dependent measurements of the resistance of ultrathin superconducting TiN films are presented. The analysis of the temperature dependence of the zero-field resistance indicates a...

    Suppression of 2D superconductivity by the magnetic field: Quantum corrections vs. The superconductor-insulator transition

    Magnetotransport of superconducting Nd2−x CexCuO4+y (NdCeCuO) films is studied in the temperature interval 0.3–30 K. The microscopic theory of the quantum corrections to conductivity, both in the Cooper and in th...

    Subgap anomaly and above-energy-gap structure in chains of diffusive SNS junctions

    We present the results of low-temperature transport measurements on chains of superconductor-normal constriction-superconductor (SNS) junctions fabricated on the basis of superconducting PtSi film. A comparati...
