The control of electrons at the level of the elementary charge e was demonstrated
experimentally already in the 1980s. Ever since, the production of an electrical current ef, or …

A ferromagnetic insulator (FI) attached to a conventional superconductor (S) changes
drastically the properties of the latter. Specifically, the exchange field at the FI/S interface …

Thermoelectric effects in metals are typically small due to the nearly perfect particle–hole
symmetry around their Fermi surface. Furthermore, thermo-phase effects and linear …

Thermal diodes,—devices that allow heat to flow preferentially in one direction—are one of
the key tools for the implementation of solid-state thermal circuits. These would find …

The Josephson effect is perhaps the prototypical manifestation of macroscopic phase
coherence, and forms the basis of a widely used electronic interferometer—the …

A superconductor with a gap in the density of states or a quantum dot with discrete energy
levels is a central building block in realizing an electronic on-chip cooler. They can work as …

The emerging field of phase-coherent caloritronics (from the Latin word calor, heat) is based
on the possibility of controlling heat currents by using the phase difference of the …

We demonstrate complete control over dynamics of a single superconducting vortex in a
nanostructure, which we coin the Single Vortex Box. Our device allows us to trap the vortex …

Under standard conditions, the electrostatic field-effect is negligible in conventional metals
and was expected to be completely ineffective also in superconducting metals. This common …

The fundamental excitations in superconductors—Bogoliubov quasiparticles—can be either
a resource or a liability in superconducting devices: they are what enables photon detection …
