Electronic structure and correlations in planar trilayer nickelate Pr4Ni3O8
Haoxiang Li, Peipei Hao, Junjie Zhang +6
The recent discovery of superconductivity in hole-doped planar nickelates R1-xSrNiO2 (R=Pr,Nd) raises the foundational question of how the electronic structure and electronic corre…
A van der Waals antiferromagnetic topological insulator with weak interlayer magnetic coupling
Chaowei Hu, Xiaoqing Zhou, Pengfei Liu +11
Magnetic topological insulators (TI) provide an important material platform to explore quantum phenomena such as quantized anomalous Hall (QAH) effect and Majorana modes, etc. Thei…
Logarithmic Upturn in Low-Temperature Electronic Transport as a Signature of d-Wave Order in Cuprate Superconductors
Xiaoqing Zhou, D. C. Peets, Benjamin Morgan +12
In cuprate superconductors, high magnetic fields have been used extensively to suppress superconductivity and expose the underlying normal state. Early measurements revealed insula…
Four-legged starfish-shaped Cooper pairs with ultrashort antinodal length scales in cuprate superconductors
Haoxiang Li, Xiaoqing Zhou, Stephen Parham +8
Cooper pairs of mutually attracting electrons form the building blocks of superconductivity. Thirty years after the discovery of high-temperature superconductivity in cuprates, man…
Observation of Topological Surface State in High Temperature Superconductor MgB2
Xiaoqing Zhou, Kyle N. Gordon, Kyung-Hwan Jin +9
The hunt for the benchmark topological superconductor (TSc) has been an extremely active research subject in condensed matter research, with quite a few candidates identified or pr…
Coexistence of Tunable Weyl Points and Topological Nodal Lines in Ternary Transition-Metal Telluride TaIrTe4
Xiaoqing Zhou, Qihang Liu, QuanSheng Wu +10
We report a combined theoretical and experimental study on TaIrTe4, a potential candidate of the minimal model of type-II Weyl semimetals. Unexpectedly, an intriguing node structur…
Spectroscopic Evidence of Low Energy Gaps Persisting Towards 120 Kelvin in Surface-Doped p-Terphenyl Crystals
Haoxiang Li, Xiaoqing Zhou, Stephen Parham +5
The possibility of high temperature superconductivity in organic compounds has been discussed since the pioneering work of Little in 1964, with unsatisfactory progress until the re…
Disorder-driven topological phase transition in Bi2Se3 films
Matthew Brahlek, Nikesh Koirala, Maryam Salehi +16
Topological insulators (TI) are a phase of matter that host unusual metallic states on their surfaces. Unlike the states that exist on the surface of conventional materials, these…
Predicted electronic markers for polytypes of LaOBiS2 examined via angular resolved photoemission spectroscopy
Xiaoqing Zhou, Qihang Liu, J. A. Waugh +7
The natural periodic stacking of symmetry-inequivalent planes in layered compounds can lead to the formation of natural superlattices; albeit close in total energy, (thus in their…
ARPES study of the Kitaev Candidate -RuCl
Xiaoqing Zhou, Haoxiang Li, Justin Waugh +7
-RuCl has been hinted as a spin-orbital-assisted Mott insulator in proximity to a Kitaev spin liquid state. Here we present ARPES measurements on single crystal -RuCl…
Hallmarks of the Mott-Metal Crossover in the Hole Doped J=1/2 Mott insulator Sr2IrO4
Yue Cao, Qiang Wang, Justin A. Waugh +12
The physics of doped Mott insulators remains controversial after decades of active research, hindered by the interplay among possible competing orders and fluctuations. It is thus…
