Robust spin correlations at high magnetic fields in the honeycomb iridates
K. A. Modic, B. J. Ramshaw, Nicholas P. Breznay +3
The complexity of the antiferromagnetic orders observed in the honeycomb iridates is a double-edged sword in the search for a quantum spin-liquid ground state: both attesting that…
The Hall number across a van Hove singularity
Akash V. Maharaj, Ilya Esterlis, Yi Zhang +2
In the context of the relaxation time approximation to Boltzmann transport theory, we examine the behavior of the Hall number, , of a metal in the neighborhood of a Lifshitz t…
Anomalous Thermal Diffusivity in Underdoped YBaCuO
J. -C. Zhang, E. M. Levenson-Falk, B. J. Ramshaw +5
We present local optical measurements of thermal diffusivity in the plane of underdoped YBCO crystals. We find that the diffusivity anisotropy is comparable to reported values…
Shubnikov-de Haas quantum oscilations reveal a reconstructed Fermi surface near optimal doping in a thin film of the cuprate superconductor PrCeCuO
Nicholas P. Breznay, Ian M. Hayes, B. J. Ramshaw +6
We study magnetotransport properties of the electron-doped superconductor PrCeCuO with = 0.14 in magnetic fields up to 92~T, and observe Shubnikov de-Haas…
Broken rotational symmetry on the Fermi surface of a high-T superconductor
B. J. Ramshaw, N. Harrison, S. E. Sebastian +6
Broken fourfold rotational (C) symmetry is observed in the experimental properties of several classes of unconventional superconductors. It has been proposed that this symmetry…
Single reconstructed Fermi surface pocket in an underdoped single layer cuprate superconductor
M. K. Chan, N. Harrison, R. D. McDonald +4
The observation of a reconstructed Fermi surface via quantum oscillations in hole-doped cuprates opened a path towards identifying broken symmetry states in the pseudogap regime. H…
