Signal transport in and conductance of correlated nanostructures
Peter Schmitteckert
Here we report on our project concerning the application of time dependent DMRG to strongly correlated systems. We show that a previously reported simulation of the spin charge sep…
Color-charge separation in trapped SU(3) fermionic atoms
Tobias Ulbricht, Rafael A. Molina, Ronny Thomale +1
Cold fermionic atoms with three different hyperfine states with SU(3) symmetry confined in one-dimensional optical lattices show color-charge separation, generalizing the conventio…
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…
Magnetic excitations in a bond-centered stripe phase: Spin waves far from the semi-classical limit
Matthias Vojta, Tobias Ulbricht
Using a spin-only model, we compute spin excitation spectra in a bond-centered stripe state with long-range magnetic order. We employ a bond operator formalism, which naturally cap…
