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…

Evidence of gate-tunable topological excitations in two-dimensional electron systems
R. Koushik, Matthias Baenninger, Vijay Narayan +5
Topological defects are ubiquitous from solid state physics to cosmology, where they drive phase transitions by proliferating as domain walls, monopoles or vortices. As quantum exc…
