Imaging the effect of drive on the low-field vortex melting phenomenon in Ba0.6K0.4Fe2As2 single crystal
Ankit Kumar, Amit Jash, Tsuyoshi Tamegai +1
Self-field imaging of current distribution in Ba0.6K0.4Fe2As2 superconductor is used to study the effect of drive on the low-field vortex solid to liquid melting phase transformati…
Theory of time-resolved optical conductivity of superconductors:comparing two methods for its evaluation
John P. Revelle, Ankit Kumar, Alexander F. Kemper
Time-resolved optical conductivity is an oft-used tool to interrogate quantum materials driven out of equilibrium. Theoretically calculating this observable is a complex topic with…
Planar pinning induced, lowering of vortex dimensionality and low field melting in a single crystal of Ba0.6K0.4Fe2As2
Ankit Kumar, Sayantan Ghosh, Tsuyoshi Tamegai +1
Theoretically, the vortex melting phenomenon occurs at both low and high magnetic fields at a fixed temperature. While the high field melting has been extensively investigated in h…
