Universal scaling behaviour near vortex-solid/glass to vortex-fluid transition in type-II superconductors in two- and three-dimensions
Hemanta Kumar Kundu, John Jesudasan, Pratap Raychaudhuri +2
In this article, we present evidence for the existence of vortex-solid/glass (VG) to vortex-fluid (VF) transition in a type-II superconductor (SC), NbN. We probed the VG to VF tran…
Effect of dimensionality on the vortex-dynamics in type-II superconductor
Hemanta Kumar Kundu, Kazi Rafsanjani Amin, John Jesudasan +3
We explore the effects of sample dimensionality on vortex pinning in a type-II, low-, s-wave superconductor, NbN, in the presence of a perpendicular magnetic field, . We fi…
The correlation between the Nernst effect and fluctuation diamagnetism in strongly fluctuating superconductors
Kingshuk Sarkar, Sumilan Banerjee, Subroto Mukerjee +1
We study the Nernst effect in fluctuating superconductors by calculating the transport coefficient in a phenomenological model where relative importance of phase and ampli…
Doping dependence of fluctuation diamagnetism in High Tc superconductors
Kingshuk Sarkar, Sumilan Banerjee, Subroto Mukerjee +1
Using a recently proposed Ginzburg-Landau-like lattice free energy functional due to Banerjee et al. Phys. Rev. B 83, 024510 (2011) we calculate the fluctuation diamagnetism of hig…
Chiral Mott insulator with staggered loop currents in the fully frustrated Bose Hubbard model
Arya Dhar, Tapan Mishra, Maheswar Maji +3
Motivated by experiments on Josephson junction arrays in a magnetic field and ultracold interacting atoms in an optical lattice in the presence of synthetic orbital magnetic fields…
Nernst effect in the vortex-liquid regime of a type-II superconductor
Subroto Mukerjee, David A. Huse
We measure the transverse thermoelectric coefficient in simulations of type-II superconductors in the vortex liquid regime, using the time-dependent Ginzburg-Landau (TDGL)…
