High-efficiency thermal switch based on topological Josephson junctions [PDF]
New Journal of Physics, 2016 We propose theoretically a thermal switch operating by the magnetic-flux controlled diffraction of phase-coherent heat currents in a thermally biased Josephson junction based on a two-dimensional topological insulator.

Preserving the Josephson Coupling of Twisted Cuprate Junctions via Tailored Silicon Nitride Circuits Boards. [PDF]
SmallReproducible twisted van der Waals heterostructures remain challenging, particularly for air‐sensitive superconductors such as BSCCO. A cryogenic, dry assembly methodology is reported, which employs silicon nitride nanomembranes with integrated electrodes, providing robust electrical contacts and pristine interfaces.

Gap resonance in the classical dynamics of the current-biased Josephson tunnel junctions
Physical Review Research, 2021 This paper reports a novel time-domain expression for the current-response kernels of a Josephson tunnel junction between BCS superconductors with in general different energy gaps, and its use to simulate the classical dynamics of such junctions.

Multiplet supercurrent in Josephson tunneling circuits
SciPost Physics, 2022 The multi-terminal Josephson effect allows DC supercurrent to flow at finite commensurate voltages. Existing proposals to realize this effect rely on nonlocal Andreev processes in superconductor-normal-superconductor junctions.
