Anomalous gap edge dissipation in disordered superconductors on the brink of localization
Bing Cheng, Liang Wu, N. J. Laurita +4
Superconductivity in disordered systems close to an incipient localization transition has been an area of investigation for many years. It has been noted that in such highly disord…
The Higgs Mode in Disordered Superconductors Close to a Quantum Phase Transition
Daniel Sherman, Uwe S. Pracht, Boris Gorshunov +10
The concept of mass-generation via the Higgs mechanism was strongly inspired by earlier works on the Meissner-Ochsenfeld effect in superconductors. In quantum field theory, the exc…
Role of the vortex-core energy on the Beresinkii-Kosterlitz-Thouless transition in thin films of NbN
Mintu Mondal, Sanjeev Kumar, Madhavi Chand +5
We analyze the occurrence of the Beresinkii-Kosterlitz-Thouless transition in thin films of NbN at various film thickness, by probing the effect of vortex fluctuations on the tempe…
Phase diagram of a strongly disordered s-wave superconductor, NbN, close to the metal-insulator transition
Madhavi Chand, Garima Saraswat, Anand Kamlapure +7
We present a phase diagram as a function of disorder in three-dimensional NbN thin films, as the system enters the critical disorder for the destruction of the superconducting stat…
Effect of Phase Fluctuations on the Superconducting Properties of Strongly Disordered 3D NbN Thin Films
Madhavi Chand, Mintu Mondal, Anand Kamlapure +8
We present transport, Hall effect, electronic tunnelling and penetration depth studies in 3D homogeneously disordered epitaxial NbN thin films with disorder ranging from the modera…
Phase fluctuations in a strongly disordered s-wave superconductor close to the metal-insulator transition
Mintu Mondal, Anand Kamlapure, Madhavi Chand +6
We explore the role of phase fluctuations in a 3-dimensional s-wave superconductor, NbN, as we approach the critical disorder for the destruction of the superconducting state. Scan…
