The embedding method beyond the single-channel case: Two-mode and Hubbard chains
Axel Freyn, Gabriel Vasseur, Peter Schmitteckert +4
We investigate the relationship between persistent currents in multi-channel rings containing an embedded scatterer and the conductance through the same scatterer attached to leads…
Is spin-charge separation observable in a transport experiment?
Tobias Ulbricht, Peter Schmitteckert
We consider a one-dimensional chain consisting of an interacting area coupled to non-interacting leads. Within the area, interaction is mediated by a local on-site repulsion. Using…

R. A. Molina J. Dukelsky P. Schmitteckert
Comment on "Spectral Signatures of the Fulde-Ferrell-Larkin-Ovchinnikov Order Parameter in One-Dimensional Optical lattices" M. Reza Bakhtiari, M. J. Leskinen, and P. Törmä, Phys.…
Spinon confinement and the Haldane gap in SU(n) spin chains
S. Rachel, R. Thomale, M. Fuehringer +2
We use extensive DMRG calculations to show that a classification of SU(n) spin chains with regard to the existence of spinon confinement and hence a Haldane gap obtained previously…
