Resilience of d-wave superconductivity to nearest-neighbor repulsion
D. Sénéchal, A. Day, V. Bouliane +1
Many theoretical approaches find d-wave superconductivity in the prototypical one-band Hubbard model for high-temperature superconductors. At strong-coupling (U > W, where U is the…
c-axis resistivity, pseudogap, superconductivity and Widom line in doped Mott insulators
G. Sordi, P. Sémon, K. Haule +1
Layered doped Mott insulators, such as the cuprates, show unusual temperature dependence of the resistivity. Intriguingly, the resistivity perpendicular to the CuO planes, $ρ_c…
Bromophenyl functionalization of carbon nanotubes : an ab initio study
Jason Beaudin, Jonathan Laflamme Janssen, Nicholas D. M. Hine +2
We study the thermodynamics of bromophenyl functionalization of carbon nanotubes with respect to diameter and metallic/insulating character using density-functional theory (DFT). O…
Vortex Lattice Melting and Hc2 in underdoped YBa2Cu3Oy
B. J. Ramshaw, James Day, Baptiste Vignolle +7
Vortices in a type-II superconductor form a lattice structure that melts when the thermal displacement of the vortices is an appreciable fraction of the distance between vortices.…
On the Origin of the Anomalous Upper Critical Field in Quasi-One-Dimensional Superconductors
Yuki Fuseya, Claude Bourbonnais, Kazumasa Miyake
Upper critical field, H_c2, in quasi-1D superconductors is investigated by the weak coupling renormalization group technique. It is shown that H_c2 greatly exceeds not only the Pau…
Magneto-elastic coupling in the spin-Peierls ground state of hydrogenated and deuterated (TMTTF)PF salts
Mario Poirier, Alexandre Langlois, Claude Bourbonnais +3
We report an ultrasonic study of the magneto-elastic coupling of the hydrogenated and deuterated (TMTTF)PF organic salts. For both salts the temperature dependence of the l…
Influence of polarizability on metal oxide properties studied by molecular dynamics simulations
Philipp Beck, Peter Brommer, Johannes Roth +1
We have studied the dependence of metal oxide properties in molecular dynamics (MD) simulations on the polarizability of oxygen ions. We present studies of both liquid and crystall…
Fano Resonances in Mid-Infrared Spectra of Single-Walled Carbon Nanotubes
François Lapointe, Étienne Gaufrés, Isabelle Tremblay +3
This work revisits the physics giving rise to the carbon nanotubes phonon bands in the mid- infrared. Our measurements of doped and undoped samples of single-walled carbon nanotube…
Extended quantum criticality of low-dimensional superconductors near a spin-density-wave instability
A. Sedeki, D. Bergeron, and C. Bourbonnais
We use the renormalization group method to study the normal state of quasi-one-dimensional superconductors nearby a spin-density-wave instability. On the basis of one-loop scatteri…
Vortex lattice studies in CeCoIn5 with H perpendicular to c
P. Das, J. S. White, A. T. Holmes +10
We present small angle neutron scattering studies of the vortex lattice (VL) in CeCoIn5 with magnetic fields applied parallel (H) to the antinodal [100] and nodal [110] directions.…
Utility of the inverse partial fluorescence for electronic structure studies of battery materials
H. Wadati, A. J. Achkar, D. G. Hawthorn +7
X-ray absorption spectroscopy (XAS) is one of the most widely used experimental techniques to study the electronic and spatial structure of materials. Fluorescence yield mode is bu…
Strong coupling superconductivity, pseudogap and Mott transition
G. Sordi, P. Sémon, K. Haule +1
An intricate interplay between superconductivity, pseudogap and Mott transition, either bandwidth driven or doping driven, occurs in materials. Layered organic conductors and cupra…
