Fermi surface topology and non-trivial Berry phase in the flat-band semimetal PdPb
Mojammel A. Khan, Po-Hao Chang, Nirmal Ghimire +5
A study of the Fermi surface of the putative topological semimetal PdPb has been carried out using Shubnikov-de Haas (SdH) oscillations measured in fields of up to 60 T. Pd…
Discovery of two-dimensional anisotropic superconductivity at KTaO (111) interfaces
Changjiang Liu, Xi Yan, Dafei Jin +15
The unique electronic structure found at interfaces between materials can allow unconventional quantum states to emerge. Here we observe superconductivity in electron gases formed…
Observation of an antiferromagnetic quantum critical point in high-purity LaNiO
Changjiang Liu, Vincent F. C. Humbert, Terence Bretz-Sullivan +12
Amongst the rare-earth perovskite nickelates, LaNiO (LNO) is an exception. While the former have insulating and antiferromagnetic ground states, LNO remains metallic and non-ma…
Superconductivity in the dilute single band limit in reduced Strontium Titanate
Terence M. Bretz-Sullivan, Alexander Edelman, J. S. Jiang +9
We report on superconductivity in single crystals of SrTiO with carrier densities , where only a single band is occupied. For all sam…
