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…
Effect of microstructure on the electronic transport properties of epitaxial CaRuO thin films
Gopi Nath Daptary, Chanchal Sow, Suman Sarkar +4
We have carried out extensive comparative studies of the structural and transport properties of CaRuO thin films grown under various oxygen pressure. We find that the preferred…
Anharmonicity in Raman-active phonon modes in atomically thin MoS
Suman Sarkar, Indrajit Maity, H. L. Pradeepa +10
Phonon-phonon anharmonic effects have a strong influence on the phonon spectrum; most prominent manifestation of these effects are the softening (shift in frequency) and broadening…
Continuous transition from weakly localized regime to strong localization regime in Nd_{0.7}La_{0.3}NiO_{3} films
Ravindra Singh Bisht, Gopi Nath Daptary, Aveek Bid +1
We report an investigation of Metal Insulator Transition (MIT) using conductivity and magnetoconductance (MC) measurements down to 0.3 K in Nd_{0.7}La_{0.3}NiO_{3} films grown on c…
Observation of Time-Reversal Invariant Helical Edge-Modes in Bilayer Graphene/WSe Heterostructure
Priya Tiwari, Saurabh Kumar Srivastav, Sujay Ray +2
Topological insulators, along with Chern insulators and Quantum Hall insulator phases, are considered as paradigms for symmetry protected topological phases of matter. This article…
