Many experimental findings in the materials family of cuprate superconductors are
converging towards an electronic picture which involves strong local Coulomb correlations …

THE interest in carbon nanotubes has been greatly stimulated by theoretical predictions that
their electronic properties are strongly modulated by small structural variations1–8. In …

IT is well known that BCS mean-field theory is remarkably successful in describing
conventional superconductors. A central concept of BCS theory is the energy gap in the …

A systematic solution of a model for copper oxides reveals a line of transitions T= T p (x) for
x, the doping away from half filling less than a critical value, to a phase with broken time …

Polarized and unpolarized neutron triple-axis spectrometry was used to study the dynamical
magnetic susceptibility χ ″(q, ω) as a function of energy (ħ ω) and wave vector (q) in a wide …

In hole-doped cuprates, Nernst experiments imply that the superconducting state is
destroyed by spontaneous creation of vortices which destroy phase coherence. Using …

We show that there are qualitative differences between the temperature dependence of the
spin and charge correlations in the normal state of the 2D attractive Hubbard model using …

We report the observation of resolved Y 89 NMR lines due to Zn nearest neighbors (nn) in
YBa 2 (Cu 1− y Zn y) 3 O 6.64. Comparison of the Curie dependence of their frequency shifts …

Using the dynamical cluster approximation and quantum Monte Carlo simulations we
calculate the single-particle spectra of the Hubbard model with next-nearest neighbor …

In the underdoped high temperature superconductors, instead of a complete Fermi surface
above T c, only disconnected Fermi arcs appear, separated by regions that still exhibit an …
