Tuning current flow in superconducting thin film strips by control wires. Applications to single photon detectors and diodes

This paper demonstrates that integrating control wires with superconducting thin film strips enables the engineering of tunable, inverted supercurrent density profiles that eliminate edge current crowding, thereby facilitating the development of wider, highly sensitive single-photon detectors and superconducting diodes.

Quantum corrections to the Josephson dynamics: a population-imbalance approach

This paper derives quantum corrections to Josephson dynamics in weakly coupled Bose-Einstein condensates by formulating a population-imbalance-only Lagrangian with position-dependent mass, demonstrating that this approach yields more accurate quantum-corrected frequencies than phase-only methods in the strong-interaction regime.

Long range proximity effects in planar structures involving the halfmetal ferromagnet La0.7Sr0.3MnO3 and Pt interlayers

This study investigates long-range triplet supercurrent transport in planar La0.7Sr0.3MnO3 Josephson junctions, revealing that while critical current systematics are hindered by fabrication inconsistencies, the introduction of a Pt interlayer successfully enables zero-resistance states at electrode distances up to 2 μm, suggesting the feasibility of even longer-range transport.

Phase Stability of Superfluid $^{3}\mathrm{He}$ in Anisotropic Aerogel

This paper investigates how anisotropic disorder in strained silica aerogel orients the vector degrees of freedom of superfluid $^{3}\mathrm{He}$ , thereby influencing the stability of its A and B phases and inducing a field-independent reorientation transition at temperature $T_x$ that is successfully described by a temperature-dependent anisotropic Ginzburg-Landau model.

Critical temperatures and critical currents of wide and narrow quasi-one-dimensional superconducting aluminum structures in zero magnetic field

This study reports that in zero magnetic field, narrower quasi-one-dimensional aluminum superconducting structures exhibit lower critical temperatures and current densities due to enhanced depairing at dirty longitudinal boundaries, while their temperature-dependent switching currents transition from Kupriyanov-Lukichev behavior at lower temperatures to linear Josephson-like behavior near the transition top, indicating the formation of SNS junctions.

Shift of the maxima of the critical currents of different polarity relative to the zero magnetic flux along the flux axis in a superconducting asymmetric aluminum ring

This paper reports the experimental observation of ac voltage rectification in asymmetric aluminum rings caused by a shift in critical current maxima relative to zero magnetic flux, and proposes a novel model attributing this shift to a temperature-dependent phase difference arising from distinct critical temperatures in the ring's semicircular segments.
