Tunable diode effect in a superconducting tunnel junction with biharmonic drive
New Journal of PhysicsA Josephson diode is a superconducting circuit element that enables non-reciprocal transport, allowing a dissipationless supercurrent to preferentially flow in a single direction.

Modulating Oxide‐Based Quantum Materials by Ion Implantation
Advanced Functional Materials, Volume 35, Issue 43, October 22, 2025.This review highlights how ion implantation, a well developed chip‐technology, enables targeted modulation of oxide‐based quantum materials. This includes tuning of metal‐insulator transitions, magnetism, and superconductivity through selective doping, defect creation, and induced lattice strain. Abstract Ion implantation has emerged as a powerful tool

Optimizing Anharmonicity in Nanoscale Weak Link Josephson Junction Oscillators
, 2009 Josephson tunnel junctions are widely used as nonlinear elements in superconducting circuits such as low noise amplifiers and quantum bits. However, microscopic defects in the oxide tunnel barrier can produce low and high frequency noise which can ...

Josephson coupling and Fiske dynamics in ferromagnetic tunnel junctions [PDF]
, 2010 . We report on the fabrication of Nb/AlOx/Pd0.82Ni0.18/Nb superconductor/insulator/ferromagnetic metal/superconductor (SIFS) Josephson junctions with high critical current densities, large normal resistance times area products, high quality factors, and ...

Programmable Cryogenic Memory in a Ge/GeSi Heterostructure
Advanced Electronic Materials, Volume 11, Issue 14, September 4, 2025.A highly programmable memory function that occurs due to a charge tunneling and trapping mechanism is demonstrated in a Ge/GeSi heterostructure field‐effect thransistor. Over three orders‐of‐magnitude control over the conductance state of the device is achieved using either the device SET or the device RESET process, suggesting potential for ...

Many-Body Effects in a Composite Bosonic Josephson Junction
AtomsIn standard bosonic Josephson junctions (BJJs), particles tunnel between two single-well potentials linked by a finite barrier. The dynamics of standard BJJs have been extensively studied, both at the many-body and mean-field levels of theory.

New Journal of PhysicsThe dynamics of bosons in Josephson junctions have drawn much attention where the bosons are initially condensed. When interacting bosons tunnel back and forth along the junction, depletion and, eventually, fragmentation develop.

Supercurrent switching in Three- and Four- Terminal Josephson Junctions
, 1998 Control of the Josephson current by varying a gate current has recently been demonstrated in both 4-terminal and 3-terminal junctions. We show that, when the the gates are weakly coupled to the Josephson junction, the Josephson current versus gate ...
