  We prove Lieb-Robinson bounds for a general class of lattice fermion systems.
By making use of a suitable conditional expectation onto subalgebras of the CAR
algebra, we can apply the Lieb-Robinson bounds much in the same way as for
quantum spin systems. We preview how to obtain the spectral flow automorphisms
and to prove stability of the spectral gap for frustration-free gapped systems
satisfying a Local Topological Quantum Order condition.
