The Kondo screening cloud: what it is and how to observe it

Ian Affleck

The Kondo effect involves the formation of a spin singlet by a magnetic impurity and conduction electrons. It is characterized by a low temperature scale, the Kondo temperature, $T…

Entanglement entropy in quantum impurity systems and systems with boundaries

Ian Affleck, Nicolas Laflorencie, Erik S. Sorensen

We review research on a number of situations where a quantum impurity or a physical boundary has an interesting effect on entanglement entropy. Our focus is mainly on impurity enta…

Diffusion and ballistic transport in one-dimensional quantum systems

J. Sirker, R. G. Pereira, I. Affleck

It has been conjectured that transport in integrable one-dimensional (1D) systems is necessarily ballistic. The large diffusive response seen experimentally in nearly ideal realiza…

Resonant Pair Tunneling in Double Quantum Dots

Eran Sela, Ian Affleck

We present exact results on the non-equilibrium current fluctuations for 2 quantum dots in series throughout a crossover from non-Fermi liquid to Fermi liquid behavior described by…

Spectral function of spinless fermions on a one-dimensional lattice

Rodrigo G. Pereira, Steven R. White, Ian Affleck

We study the spectral function of interacting one-dimensional fermions for an integrable lattice model away from half-filling. The divergent power-law singularity of the spectral f…
