Kavli Affiliate: Yu V. Nazarov | Summary:We present an exhaustive theoretical analysis of a double-loop Josephson proximity interferometer, as the one recently realized by Strambini et al. for the control of the Andreev spectrum via an external magnetic field. This system, called $ω$-SQUIPT, consists of a T-shaped diffusive normal metal (N) attached to three superconductors […]

Kavli Affiliate: Timon Idema | Summary:Many biological systems form colonies at high density. Passive granular systems will be jammed at such densities, yet for the survival of biological systems it is crucial that they are dynamic. We construct a phase diagram for a system of active particles interacting via Vicsek alignment, and vary the density, […]
