Melting of the Vortex Lattice through Intermediate Hexatic Fluid in an Thin Film

I Roy, S Dutta, AN Roy Choudhury, S Basistha… - Physical review …, 2019 - APS
The hexatic fluid refers to a phase in between a solid and a liquid that has short-range
positional order but quasi-long-range orientational order. In the celebrated theory of …

Evidence of zero-point fluctuation of vortices in a very weakly pinned -MoGe thin film

S Dutta, I Roy, J Jesudasan, S Sachdev… - Physical Review B, 2021 - APS
In a type-II superconductor, the vortex core (VC) behaves like a normal metal. Consequently,
the single-particle density of states in the VC of a conventional type-II superconductor …

Influence of pressure on the transport, magnetic, and structural properties of superconducting Cr 0.0009 NbSe 2 single crystal

K Manikandan, R Pervin, C Saravanan… - RSC …, 2020 - pubs.rsc.org
We investigate the superconducting critical current density (Jc), transition temperature (Tc),
and flux pinning properties under hydrostatic pressure (P) for Cr0. 0009NbSe2 single …

Enigma of the vortex state in a strongly correlated -wave superconductor

A Datta, HJ Changlani, K Yang, A Ghosal - Physical Review B, 2023 - APS
We show that strong electronic repulsion transforms a vortex core from a metallic type in the
overdoped regime to a Mott insulator at underdoping of a strongly correlated d-wave …

Vortex phase diagram study in the superconductor Ca3Ir4Sn13

S Kumar, RP Singh, A Thamizhavel… - Materials Research …, 2018 - iopscience.iop.org
We present the vortex phase diagram for a single crystal of a low T c superconductor, Ca 3 Ir
4 Sn 13 explored via detailed ac magnetic susceptibility (${\chi}^{{\prime}}(H, T) $) and ac …

Dinámica de vórtices superconductores en la región de transición orden-desorden

M Marziali Bermúdez - 2018 - bibliotecadigital.exactas.uba.ar
En los superconductores de tipo II el campo magnético penetra en líneas de flujo
cuantizadas, conocidas como vórtices. La materia de vórtices constituye un sistema modelo …
