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…
Graphene resonator as an ultrasound detector for generalized Love waves in a polymer film with two level states
Antti Laitinen, Jukka-Pekka Kaikkonen, Thanniyil S. Abhilash +6
We have investigated surface shear waves at 22 MHz in a 0.5-micron-thick polymer film on SiO2/Si substrate at low temperatures using suspended and non-suspended graphene as detecto…
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…
Quartz tuning fork as a probe of surface waves
Igor Todoshchenko, Alexander Savin, Miika Haataja +2
Quartz tuning forks are high-quality mechanical oscillators widely used in low temperature physics as viscometers, thermometers and pressure sensors. We demonstrate that a fork pla…
