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…
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…
Diamagnetism and density wave order in the pseudogap regime of YBaCuO
Lauren E. Hayward, Andrew J. Achkar, David G. Hawthorn +2
Clear experimental evidence of charge density wave correlations competing with superconducting order in YBCO have thrust their relationship with the pseudogap regime into the spotl…
The symmetry of charge order in cuprates
R. Comin, R. Sutarto, F. He +13
Charge-ordered ground states permeate the phenomenology of 3d-based transition metal oxides, and more generally represent a distinctive hallmark of strongly-correlated states of ma…
