Spin transport in a one-dimensional quantum wire
A. -M. Visuri, M. Lebrat, S. Häusler +2
We analyze the spin transport through a finite-size one-dimensional interacting wire connected to noninteracting leads. By combining renormalization-group arguments with other anal…

Impurity coupled to a lattice with disorder
A. -M. Visuri, C. Berthod, T. Giamarchi
We study the time-dependent occupation of an impurity state hybridized with a continuum of extended or localized states. Of particular interest is the return probability, which giv…
