Anomalous Nodal Gap in a Doped Spin-1/2 Antiferromagnetic Mott Insulator
Yong Hu, Christopher Lane, Xiang Chen +10
Many emergent phenomena appear in doped Mott insulators near the insulator-to-metal transition. In high-temperature cuprate superconductors, superconductivity arises when antiferro…
Impact of charge-density-wave pattern on the superconducting gap in V-based kagome superconductors
T. Nagashima, K. Ishihara, Y. Yamakawa +12
Kagome metals VSb ( K, Rb, Cs) provide a compelling platform to explore the interplay between superconductivity (SC) and charge-density-wave (CDW) orders. While dist…
High-pressure floating zone crystal growth of SrIrO
S. J. Gomez Alvarado, Y. Pang, P. A. Barrera +7
Here we demonstrate the floating zone crystal growth of the Mott insulator SrIrO. Historically, the growth of iridates from a ternary melt has been pre…
A Hubbard exciton fluid in a photo-doped antiferromagnetic Mott insulator
Omar Mehio, Xinwei Li, Honglie Ning +7
The undoped antiferromagnetic Mott insulator naturally has one charge carrier per lattice site. When it is doped with additional carriers, they are unstable to spin fluctuation-med…
Observation of excitons bound by antiferromagnetic correlations
Omar Mehio, Yuchen Han, Xinwei Li +4
Two-dimensional Mott insulators host antiferromagnetic (AFM) correlations that are predicted to enhance the attractive interaction between empty (holons) and doubly occupied (doubl…
Impurity-induced moment freezing in NaFeRuO
Alon Hendler Avidor, Brenden R. Ortiz, Paul M. Sarte +2
We report the impact of magnetic impurity substitution on the quantum disordered magnetic ground state of NaRuO. Local moments are introduced into the frustrated triang…
