Probing the Superconducting Gap of Lead With Ballistic Phonons
The assumption that quasiparticles are all in thermal equilibrium with the helium-bath leads to erroneous results for temperature dependences of phonon absorption. Instead, we assume that the phonon-imaging experiment creates small regions of raised temperature that contribute non-equilibrium …

Charge dynamics in superconducting double dots
… bands corresponding to charge states with single quasiparticles in one or both islands. These devices are fabricated using shadow mask evaporation, and are measured at sub Kelvin temperatures using a dilution refrigerator. We use radio frequency reflectometry to measure quantum capacitance, which …
