Flux-flow instability across Berezinskii Kosterlitz Thouless phase transition in KTaO (111) based superconductor
Shashank Kumar Ojha, Prithwijit Mandal, Siddharth Kumar +2
The nature of energy dissipation in 2D superconductors under perpendicular magnetic field at small current excitations has been extensively studied over the past two decades. Howev…

Probing long-range correlations in the Berezinskii-Kosterlitz-Thouless fluctuation regime of ultra-thin NbN superconducting films using transport noise measurements
R. Koushik, Siddhartha Kumar, Kazi Rafsanjani Amin +5
We probe the presence of long-range correlations in phase fluctuations by analyzing the higher-order spectrum of resistance fluctuations in ultra-thin NbN superconducting films. Th…
