Reversibility of Superconducting Nb Weak Links Driven by the Proximity Effect in a Quantum Interference Device
Nikhil Kumar, T. Fournier, H. Courtois +2
We demonstrate the role of proximity effect in the thermal hysteresis of superconducting constrictions. From the analysis of successive thermal instabilities in the transport chara…
Evidence for topological surface states in metallic single crystals of Bi2Te3
Sourabh Barua, K. P. Rajeev, Anjan K. Gupta
Bi2Te3 is a member of a new class of materials known as topological insulators which are supposed to be insulating in the bulk and conducting on the surface. However experimental v…
Temperature and phase dynamics in superconducting weak-link
Anjan K. Gupta, Nikhil Kumar, Sourav Biswas
A time dependent thermal model for a superconducting constriction based weak-link (WL) is discussed for investigating the deterministic dynamics of its temperature and phase. A new…
Electronic inhomogeneities in the superconducting phase of CaFe1.96Ni0.04As2 single crystals
Anirban Dutta, Neeraj Kumar, A. Thamizhavel +1
Superconductivity in Iron-Arsenic based pnictides emerges in close proximity to an antiferromagnetic (AFM)ordered parent state and the AFM phase overlaps with superconducting (SC)…
