Self-heating effects are experimentally investigated in a graphene multiterminal Josephson junction and simulated using a resistively shunted Josephson junction network model. Self-heating is also shown to significantly influence the switching dynamics of this multiterminal system.

The transition from edge-dominated to bulk-dominated quantum interference patterns of supercurrents in a quantum anomalous Hall-based Josephson junction is investigated. An anomalous Fraunhofer-like pattern is observed due to the bulk carriers induced by magnetic domains, even when the chemical potential resides within the bulk gap.

One-dimensional -wave superconductors can reside in a topological phase and are predicted to host non-Abelian states at their ends. It is shown that attractive interactions mediated by magnons can induce intrinsic triplet superconductivity in an electronic chain in proximity to a spin spiral, and combined with the effects from coupling to the static spin spiral the magnon-mediated interaction stabilizes a topological superconducting phase.
