    Quasiparticle tunneling as a probe of Josephson junction barrier and capacitor material in superconducting qubits

    Non-equilibrium quasiparticles are possible sources for decoherence in superconducting qubits because they can lead to energy decay or dephasing upon tunneling across Josephson junctions (JJs). Here, we invest...

    Evidence for an anomalous current–phase relation in topological insulator Josephson junctions

    Josephson junctions with topological insulator weak links can host low-energy Andreev-bound states giving rise to a current–phase relation that deviates from sinusoidal behaviour. Of particular interest are ze...

    Exciton condensation and perfect Coulomb drag

    An electronic current flowing in one conductor can induce a drag current in another spatially separated conductor by means of Coulomb interactions; when these interactions are sufficiently strong the currents ...
