Edge singularities in high-energy spectra of gapped one-dimensional magnets in strong magnetic fields
A. Friedrich, A. K. Kolezhuk, I. P. McCulloch +1
We use the dynamical density matrix renormalization group technique to show that the high-energy part of the spectrum of a S=1 Haldane chain, placed in a strong external magnetic f…

Mixture of bosonic and spin-polarized fermionic atoms in an optical lattice
Lode Pollet, Corinna Kollath, Ulrich Schollwoeck +1
We investigate the properties of trapped Bose-Fermi mixtures for experimentally relevant parameters in one dimension. The effect of the attractive Bose-Fermi interaction onto the b…
