Intrinsic Quasiparticle Lifetime in a Superconducting Aluminum
Konrad Norowski, Marek Foltyn, Alexander Savin +1
We use time-resolved thermometry to monitor the decay of nonequilibrium quasiparticles in superconducting Al in the temperature range from K to K. The quasiparticle l…
Quantum thermodynamics with a single superconducting vortex
Marek Foltyn, Konrad Norowski, Alexander Savin +1
We demonstrate complete control over dynamics of a single superconducting vortex in a nanostructure which we coin the Single Vortex Box (SVB). Our device allows us to trap the vort…
Stochastic thermal feedback in switching measurements of superconducting nanobridge caused by overheated electrons and phonons
Maciej Zgirski, Marek Foltyn, Alexander Savin +1
We study correlated switchings of superconducting nanobridge probed with train of current pulses. For pulses with low repetition rate each pulse transits the superconducting bridge…
Heat hunting in freezer: Direct measurement of quasiparticle diffusion in superconducting nanowire
Maciej Zgirski, Marek Foltyn, Alexander Savin +2
Propagation and relaxation of nonequilibrium quasiparticles in superconductors are of key importance for functioning of numerous nanoscale devices, enabling operation of some of th…
Flipping coin experiment for studying switching in Josephson junctions and superconducting wires
Marek Foltyn, Konrad Norowski, Alexander Savin +1
Josephson junctions and superconducting wires when probed with current pulses exhibit stochastic switching from superconducting to a stable non-zero voltage state. Electrical curre…
Nanosecond thermometry with Josephson junction
M. Zgirski, M. Foltyn, A. Savin +2
We demonstrate a novel approach to thermometry at the nanoscale exploiting a superconducting weak link. Such a weak link probed with nanosecond current pulses serves as a temperatu…
