Stability of thermally bistable states and their switching in superconducting weak link
Sourav Biswas, Pankaj Wahi, Anjan Kumar Gupta
Superconducting weak link (WL), acting as a Josephson junction (JJ), is one of the widely used elements in superconductor science and quantum circuits. A hysteretic JJ with robust…
A thermal model with AC Josephson effect for a shunted superconducting weak-link
Sourav Biswas, Anjan Kumar Gupta
Superconducting weak-link (WL), behaving like a Josephson junction (JJ), is fundamental to many superconducting devices such as nanoSQUIDs, single-photon detectors, and bolometers.…
Elimination of thermal bistability in superconducting weak links by an inductive shunt
Sourav Biswas, Clemens B. Winkelmann, Hervé Courtois +3
The quantum phase-coherent behavior of superconducting weak links (WL) is often quenched in the finite voltage state, due to the heat dissipation and related thermal hysteresis. Th…
Josephson Coupling in the Dissipative State of a Thermally Hysteretic -SQUID
Sourav Biswas, Clemens B. Winkelmann, Hervé Courtois +1
Micron-sized superconducting interference devices (-SQUIDs) based on constrictions optimized for minimizing thermal runaway are shown to exhibit voltage oscillations with applie…
Micron size superconducting quantum interference devices of lead (Pb)
Sagar Paul, Sourav Biswas, Anjan K. Gupta
Micron size superconducting quantum interference devices (-SQUID) of lead (Pb), for probing nano-magnetism, were fabricated and characterized. In order to get continuous Pb film…
Controlling hysteresis in superconducting constrictions with a resistive shunt
Nikhil Kumar, C. B. Winkelmann, Sourav Biswas +2
We demonstrate control of the thermal hysteresis in superconducting constrictions by adding a resistive shunt. In order to prevent thermal relaxation oscillations, the shunt resist…
