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…
Fermi Liquid Theory for the Persistent Current Past a Side-Coupled Quantum Dot
Ian Affleck, Erik S. Sørensen
A Fermi Liquid theory is developed for the persistent current past a side coupled quantum dot yielding analytical predictions for the behavior of the first two harmonics of the per…
Kondo Screening Cloud and Charge Quantization in 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…
Impurity Entanglement Entropy and the Kondo Screening Cloud
Erik S. Sørensen, Ming-Shyang Chang, Nicolas Laflorencie +1
The screening of an impurity spin by conduction electrons is associated with the formation of a large Kondo screening cloud, of size xi_K. We study the quantum entanglement between…
The dynamical spin structure factor for the anisotropic spin-1/2 Heisenberg chain
R. G. Pereira, J. Sirker, J. -S. Caux +4
The longitudinal spin structure factor for the XXZ-chain at small wave-vector q is obtained using Bethe Ansatz, field theory methods and the Density Matrix Renormalization Group. I…
