Friedel oscillations and the Kondo screening cloud
Ian Affleck, Laszlo Borda, Hubert Saleur
We show that the long distance charge density oscillations in a metal induced by a weakly coupled spin-1/2 magnetic impurity exhibiting the Kondo effect are given, at zero temperat…
Kondo screening cloud and the charge staircase in one-dimensional mesoscopic devices
Rodrigo G. Pereira, Nicolas Laflorencie, Ian Affleck +1
We propose that the finite size of the Kondo screening cloud, xi_K, can be probed by measuring the charge quantization in a one-dimensional system coupled to a small quantum dot. W…
Thermodynamics of impurities in the anisotropic Heisenberg spin-1/2 chain
J. Sirker, S. Fujimoto, N. Laflorencie +2
The thermodynamics of finite open antiferromagnetic XXZ chains is studied using field theory, Bethe Ansatz and quantum Monte Carlo methods. For the susceptibility a parameter-free…
Kondo Effect in Spin Chains
Nicolas Laflorencie, Erik S. Sørensen, Ian Affleck
The free electron Kondo problem can be described by a one-dimensional (1D) model because only the s-wave part of the electronic wave-function is affected by the Kondo coupling. Sin…
Boson decay and the dynamical structure factor for the XXZ chain at finite magnetic field
J. Sirker, R. G. Pereira, J. -S. Caux +4
We study the longitudinal dynamical structure factor for the anisotropic spin-1/2 (XXZ) chain at finite magnetic field using bosonization. The leading irrelevant oper…
Probing the pairing symmetry and pair charge stiffness of doped ladders
A. E. Feiguin, S. R. White, D. J. Scalapino +1
We perform the numerical equivalent of a phase sensitive experiment on doped ladders. We apply proximity effect fields with different complex phases at both ends of an open s…
