In the recently discovered iron-based superconductors,the electronic anisotropy as revealed by scanning tunneling microscopy(STM)and transport measurements has attracted intensive attention.
Motivated by the recent atomic-scale STM observations of a spatially localized in-gap state in the doped Mott insulators[1],we study theoretically the local electronic state in a single electron doped
Very recently,there are accumulating experiments show evidence on that the "in-gap" state in Kondo insulator SmB6 could be ascribed to topological surface state(TSS).
We have performed measurements of quantum oscillations and specific heat at low temperatures and in pulsed magnetic fields across the ambient-pressure field-induced antiferromagnetic quantum critical
We report an optical spectroscopy investigation of single crystals of Na2Ti2Sb2O,which is parent compound for the newly discovered Ti-based superconductors.
Topological insulators represent a new quantum state of matter that are insulating in the bulk but metallic on the edge or surface possessing a unique electronic structure and spin texture.
Electronic orders in a correlated system at van Hove singularities are rich but challenging since two or more kinds of orders may be equally competitive.
