Vanishing nematic order beyond the pseudogap phase in overdoped cuprate superconductors
Naman K. Gupta, C. McMahon, R. Sutarto +9
During the last decade, translational and rotational symmetry-breaking phases -- density wave order and electronic nematicity -- have been established as generic and distinct featu…
Evidence for bond-disproportionation in LiNiO2 from x-ray absorption spectroscopy
R. J. Green, H. Wadati, T. Z. Regier +7
The electronic structure of LiNiO, a promising Li-ion battery cathode material, has remained a challenge to understand due to its highly covalent yet correlated nature. Here we…
Orbital Symmetries of Charge Density Wave Order in YBa2Cu3O6+x
Christopher McMahon, A. J. Achkar, E. H. da Silva Neto +10
Charge density wave (CDW) order has been shown to compete and coexist with superconductivity in underdoped cuprates. Theoretical proposals for the CDW order include an unconvention…
Synthesis of high-oxidation Y-Ba-Cu-O phases in superoxygenated thin films
H. Zhang, N. Gauquelin, C. McMahon +3
It is known that solid-state reaction in high-pressure oxygen can stabilize high-oxidation phases of Y-Ba-Cu-O superconductors in powder form. We extend this superoxygenation conce…
Nematicity in stripe ordered cuprates probed via resonant x-ray scattering
A. J. Achkar, M. Zwiebler, Christopher McMahon +12
In underdoped cuprate superconductors, a rich competition occurs between superconductivity and charge density wave (CDW) order. Whether rotational symmetry breaking (nematicity) oc…
Orbital symmetry of charge density wave order in La1.875Ba0.125CuO4 and YBa2Cu3O6.67
A. J. Achkar, F. He, R. Sutarto +9
Recent theories of charge density wave (CDW) order in high temperature superconductors have predicted a primarily d CDW orbital symmetry. Here, we report on the orbital symmetry of…
Impact of Quenched Oxygen Disorder on Charge Density Wave Order in YBaCuO
A. J. Achkar, X. Mao, Christopher McMahon +6
The competition between superconductivity and charge density wave (CDW) order in underdoped cuprates has now been widely reported, but the role of disorder in this competition has…
