Bandstructure of fermions in the Heisenberg chain

Caption

Bandstructure of fermions in the Heisenberg chain: The red line shows the bare bandstructure in the fermionic representation for a Heisenberg spin chain in a finite magnetic field (Hz), whereas the blue dotted lines display two folded bands caused by the interchain incommensurate “molecular” field produced by the neighboring chains . The green horizontal line shows the position of the chemical potential. Red arrows indicate paths for multiple scattering.
