Evidence of incoherent carriers associated with resonant impurity levels and their influence on superconductivity in the anomalous superconductor PbTlTe
P. Giraldo-Gallo, P. Walmsley, B. Sangiorgio +9
We present a combined experimental and theoretical study of the evolution of the Fermi surface of the anomalous superconductor PbTlTe as a function of thallium concentr…
Mass enhancement in multiple bands approaching optimal doping in a high-temperature superconductor
C. M. Moir, Scott C. Riggs, J. A. Galvis +7
Pnictides provide an opportunity to study the effects of quantum criticality in a multi-band high temperature superconductor. Quasiparticle mass divergence near optimal doping, obs…
Measurement of the elastoresistivity coefficients of the underdoped iron-arsenide Ba(FeCo)As
Hsueh-Hui Kuo, Maxwell C. Shapiro, Scott C. Riggs +1
A new method is presented for measuring terms in the elastoresistivity tensor of single crystal samples with tetragonal symmetry. The technique is applied to a representat…
Bounding the pseudogap with a line of phase transitions in YBCO cuprate superconductors
Arkady Shekhter, B. J. Ramshaw, Ruixing Liang +7
Close to optimal doping, the copper oxide superconductors show 'strange metal' behavior, suggestive of strong fluctuations associated with a quantum critical point. Such a critical…
On the origin of non-monotonic doping dependence of the in-plane resistivity anisotropy in Ba(Fe)As, = Co, Ni and Cu
Hsueh-Hui Kuo, Jiun-Haw Chu, Scott C. Riggs +6
The in-plane resistivity anisotropy has been measured for detwinned single crystals of Ba(FeNi)As and Ba(FeCu)As. The data reveal a non-mono…
Planes, Chains, and Orbits: Quantum Oscillations and High Magnetic Field Heat Capacity in Underdoped YBCO
Scott C. Riggs, O. Vafek, J. B. Kemper +6
The underlying physics of the magnetic-field-induced resistive state in high temperature cuprate superconductors remains a mystery. One interpretation is that the application of ma…
