In noncentrosymmetric materials, the responses (for example, electrical and optical)
generally depend on the direction of the external stimuli, called nonreciprocal phenomena …

Stimulated by the recent experiment [F. Ando, Nature (London) 584, 373 (2020). NATUAS
0028-0836 10.1038/s41586-020-2590-4], we propose an intrinsic mechanism to cause the …

Abstract Research activities in Superconducting Nanowire Single Photon Detectors
(SNSPDs) have exhibited major progress over last two decades. The low dark count rate …

The normal state of optimally doped cuprates is dominated by the “strange metal” phase that
shows a linear temperature (T) dependence of the resistivity persisting down to the lowest T …

In superconductors, the motion of vortices introduces unwanted dissipation that is disruptive
to applications. Fortunately, material defects can immobilize vortices, acting as vortex …

The addition of artificial pinning centers has led to an impressive increase in the critical
current density (J c) of superconductors, enabling record-breaking all-superconducting …

We report on the growth and characterization of ultrathin YBa 2 Cu 3 O 7− δ (YBCO) films on
MgO (110) substrates, which exhibit superconducting properties at thicknesses down to 3 …

We have grown and characterized 30-nm-thick YBa 2 Cu 3 O 7− δ (YBCO) films, deposited
by pulsed laser deposition on both MgO (110) and SrTiO 3 (001) substrates, which induce …

We report the fabrication of nanoscale wires and Josephson junctions in 25 nm thick YBa 2
Cu 3 O 7–δ thin films with wire widths as narrow as 50 nm. Our approach utilizes a finely …

We present results on ultra low noise YBa 2 Cu 3 O 7–δ (YBCO) nano Superconducting
QUantum Interference Devices (nanoSQUIDs). To realize such devices, we implemented …
