NaFeCuAs: A pnictide insulating phase induced by on-site Coulomb interaction
C. E. Matt, N. Xu, B. Q. Lv +13
In the studies of iron-pnictides, a key question is whether their bad-metal state from which the superconductivity emerges lies in close proximity with a magnetically ordered insul…
Tuning the metal-insulator transition in NdNiO3 heterostructures via Fermi surface instability and spin-fluctuations
R. S. Dhaka, Tanmoy Das, N. C. Plumb +11
We employed {\it in-situ} pulsed laser deposition (PLD) and angle-resolved photoemission spectroscopy (ARPES) to investigate the mechanism of the metal-insulator transition (MIT) i…
Exotic Kondo crossover in a wide temperature region in the topological Kondo insulator SmB6 revealed by high-resolution ARPES
N. Xu, C. E. Matt, E. Pomjakushina +12
Temperature dependence of the electronic structure of SmB6 is studied by high-resolution ARPES down to 1 K. We demonstrate that there is no essential difference for the dispersions…
Direct observation of the spin texture in strongly correlated SmB6 as evidence of the topological Kondo insulator
N. Xu, P. K. Biswas, J. H. Dil +18
The concept of a topological Kondo insulator (TKI) has been brought forward as a new class of topological insulators in which non-trivial surface states reside in the bulk Kondo ba…
Surface vs bulk electronic structures of a moderately correlated topological insulator YbB6 revealed by ARPES
N. Xu, C. E. Matt, E. Pomjakushina +14
Systematic angle-resolved photoemission spectroscopy (ARPES) experiments have been carried out to investigate the bulk and (100) surface electronic structures of a topological mixe…
