batteries have enormous development potential and a broad market outlook in the field of …

During the past 15 years a new field has emerged, which combines superconductivity and
spintronics, with the goal to pave a way for new types of devices for applications combining …

Frustration, the presence of competing interactions, is ubiquitous in the physical sciences
and is a source of degeneracy and disorder, which in turn gives rise to new and interesting …

This review provides a theoretical basis for understanding the current-phase relation (CΦR)
for the stationary (dc) Josephson effect in various types of superconducting junctions. The …

Frustration, defined as a competition between interactions such that not all of them can be
satisfied, is important in systems ranging from neural networks to structural glasses …

The magnetic sensing at nanoscale level is a promising and interesting research topic of
nanoscience. Indeed, magnetic imaging is a powerful tool for probing biological, chemical …

Josephson junctions enable dissipation-less electrical current through metals and insulators
below a critical current. Despite being central to quantum technology based on …

Recent advances in nanotechnology allow model systems to be constructed, in which
frustrated interactions can be tuned at will, such as artificial spin ice. The symmetry of the …

High operation speed and low energy consumption may allow the superconducting digital
single-flux-quantum circuits to outperform traditional complementary metal–oxide …
