Chiral adiabatic transmission protected by Fermi surface topology

Isidora Araya Day, Kostas Vilkelis, Antonio L. R. Manesco +3

We demonstrate that Andreev modes that propagate along a transparent Josephson junction have a perfect transmission at the point where three junctions meet. The chirality and the n…

Dissipationless Nonlinearity in Quantum Material Josephson Diodes

Constantin Schrade, Valla Fatemi

Dissipationless nonlinearities for three-wave mixing are a key component of many superconducting quantum devices, such as amplifiers and bosonic qubits. So far, such third-order no…
