A multi-component Fermi surface in the vortex state of an underdoped high-Tc superconductor
Suchitra E. Sebastian, N. Harrison, E. Palm +6
In order to understand the origin of superconductivity, it is crucial to ascertain the nature and origin of the primary carriers available to participate in pairing. Recent quantum…
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…
Compensated electron and hole pockets in an underdoped high Tc superconductor
Suchitra E. Sebastian, N. Harrison, P. A. Goddard +7
We report quantum oscillations in the underdoped high Tc YBCO over a wide range in magnetic field 28<B<85 T corresponding to ~12 oscillations, enabling the Fermi surface topology t…
Spin-order driven Fermi surface revealed by quantum oscillations in an underdoped high Tc superconductor
Suchitra E. Sebastian, N. Harrison, C. H. Mielke +4
We use quantum oscillation measurements to distinguish between spin and orbital components of the lowest energy quasiparticle excitations in YBa2Cu3O6.54, each of which couple diff…
