Spontaneous orbital polarization in the nematic phase of FeSe
Connor A. Occhialini, Joshua J. Sanchez, Qian Song +5
The origin of nematicity in FeSe remains a critical outstanding question towards understanding unconventional superconductivity in proximity to nematic order. To understand what dr…
Strain-Switchable Field-Induced Superconductivity
Joshua J. Sanchez, Gilberto Fabbris, Yongseong Choi +9
Field-induced superconductivity is a rare phenomenon where an applied magnetic field enhances or induces superconductivity. This fascinating effect arises from a complex interplay…
Role of Oxygen States in the Low Valence Nickelate LaNiO
Y. Shen, J. Sears, G. Fabbris +13
The discovery of superconductivity in square-planar low valence nickelates has ignited a vigorous debate regarding their essential electronic properties: Do these materials have ap…
Strongly anisotropic antiferromagnetic coupling in EuFe2As2 revealed by stress detwinning
Joshua J Sanchez, Gilberto Fabbris, Yongseong Choi +8
Of all parent compounds of iron-based high-temperature superconductors, EuFe2As2 exhibits by far the largest magnetostructural coupling due to the sizable biquadratic interaction b…
Strong Superexchange in a Nickelate Revealed by Resonant Inelastic X-Ray Scattering
J. Q. Lin, P. Villar Arribi, G. Fabbris +20
The discovery of superconductivity in a nickelate has inspired disparate theoretical perspectives regarding the essential physics of this class of materials. A key issue…
Charge density waves in cuprate superconductors beyond the critical doping
H. Miao, G. Fabbris, R. J. Koch +17
The unconventional normal-state properties of the cuprates are often discussed in terms of emergent electronic order that onsets below a putative critical doping of xc = 0.19. Char…
Persistent Charge Density Wave Memory in a Cuprate Superconductor
X. M. Chen, C. Mazzoli, Y. Cao +12
Although charge density wave (CDW) correlations appear to be a ubiquitous feature of the superconducting cuprates, their disparate properties suggest a crucial role for coupling or…
Pressure-induced superconductivity in elemental ytterbium metal
Jing Song, James S. Schilling
Ytterbium (Yb) metal is divalent and nonmagnetic but would be expected under sufficient pressure to become trivalent and magnetic. We have carried out electrical resistivity and ac…
Incommensurate phonon anomaly and the nature of charge density waves in cuprates
H. Miao, D. Ishikawa, R. Heid +6
While charge density wave (CDW) instabilities are ubiquitous to superconducting cuprates, the different ordering wavevectors in various cuprate families have hampered a unified des…
Pressure-induced collapsed-tetragonal phase in SrCo2As2
W. T. Jayasekara, U. S. Kaluarachchi, B. G. Ueland +16
We present high-energy x-ray diffraction data under applied pressures up to p = 29 GPa, neutron diffraction measurements up to p = 1.1 GPa, and electrical resistance measurements u…
Pressure and chemical substitution effects in the local atomic structure of BaFe2As2
E. Granado, L. Mendonca-Ferreira, F. Garcia +10
The effects of K and Co substitutions and quasi-hydrostatic applied pressure (P<9 GPa) in the local atomic structure of BaFe2As2, Ba(Fe{0.937}Co{0.063})2As2 and Ba{0.85}K{0.15}Fe2A…
