Coherence, long-range transport and nuclear polarization in a driven-dissipative dark exciton condensate
Amit Jash, Maheswar Swar, Uri Shimon +2
We report direct evidence for macroscopic coherence in a condensate of dark dipolar excitons in coupled quantum wells and show that its formation follows a non-equilibrium, driven-…
Giant Hyperfine Interaction between a Dark Exciton Condensate and Nuclei
Amit Jash, Michael Stern, Subhradeep Misra +2
We study the interaction of a dark exciton Bose-Einstein condensate with the nuclei in GaAs/AlGaAs coupled quantum wells and find clear evidence for nuclear polarization buildup th…
Exploration of strongly correlated states in SmB6 through a comparison of its two-coil pick-up response to that of Bi2Se3
Sayantan Ghosh, Sugata Paul, Amit Jash +2
Earlier studies on the Kondo insulator SmB6 reveal the presence of a bulk Kondo insulating gap between 30 - 50 K, and the emergence of a conducting surface state only below 4 K. He…
Imaging the topological current carrying state and the surface to bulk transformation, in Bi2Se3 single crystal and thin film
Amit Jash, Ankit Kumar, Sayantan Ghosh +2
Magneto-optics based current imaging technique compares the nature of topological current distribution in a single crystal and thin film of topological insulator material, Bi2Se3.…
Coupling-decoupling of conducting topological surface states in thick BiSe single crystals
Amit Jash, Sayantan Ghosh, A. Bharathi +1
Sensitive ac susceptibility measurements of a topological insulator, BiSe single crystal, using mutual two coil inductance technique (Ref. 32) shows coupling and decoupling…
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…
