The Dirac fermion is an important fundamental particle appearing in high-energy
physics and topological insulator physics. In particular, a Dirac fermion in a
one-dimensional lattice system exhibits the essential properties of topological
physics. However, the system has not been quantum simulated in experiments yet.
Herein, we propose a one-dimensional generalized lattice Wilson-Dirac fermion
model and study its topological phase structure. We show the experimental setups
of an atomic quantum simulator for the model, in which two parallel optical
lattices with the same tilt for trapping cold fermion atoms and a laser-assisted
hopping scheme are used. Interestingly, we find that the model exhibits
nontrivial topological phases characterized by gapless edge modes and a finite
winding number in the broad regime of the parameter space. Some of the phase
diagrams closely resemble those of the Haldane model. We also discuss topological
charge pumping and a lattice Gross-Neveu model in the system of generalized
Wilson-Dirac fermions.
