Theory of Resistivity Upturns in Metallic Cuprates
W. Chen, Brian M. Andersen, P. J. Hirschfeld
We propose that the experimentally observed resistivity upturn of cuprates at low temperatures may be explained by properly accounting for the effects of disorder in a strongly cor…
Effects of cobalt doping and three-dimensionality in
A. F. Kemper, C. Cao, P. J. Hirschfeld +1
We investigate the dual roles of a cobalt impurity in the Ba-122 ferropnictide superconductor in the state with coexisting collinear spin density wave (SDW) order as a dopant and a…
Origin of Gap Anisotropy in Spin Fluctuation Models of the Fe-pnictides
T. A. Maier, S. Graser, D. J. Scalapino +1
We discuss the large gap anisotropy found for the A1g (s-wave) state in RPA spin-fluctuation and functional renormalization group calculations and show how the simple arguments lea…
Extinction of quasiparticle interference in underdoped cuprates with coexisting order
Brian M. Andersen, P. J. Hirschfeld
Recent scanning tunnelling spectroscopy measurements [Y. Koksaka et al., Nature 454, 1072 (2008)] have shown that dispersing quasiparticle interference peaks in Fourier transformed…
Tc suppression and resistivity in cuprates with out of plane defects
S. Graser, T. Dahm, P. J. Hirschfeld +1
Recent experiments introducing controlled disorder into optimally doped cuprate superconductors by both electron irradiation and chemical substitution have found unusual behavior i…
Disorder-Induced Static Antiferromagnetism in Cuprate Superconductors
Brian M. Andersen, P. J. Hirschfeld, Arno P. Kampf +1
Using model calculations of a disordered d-wave superconductor with on-site Hubbard repulsion, we show how dopant disorder can stabilize novel states with antiferromagnetic order.…
