"(3+1) massive Dirac fermions with   ultracold atoms in optical lattice"



Abstract



I discuss a cold-atoms set-up able to simulate (3+1) Dirac fermions  
and some applications, relevant both in elementary particle and in  
condensed matter physics. I show in particular the possibility to add  
a tunable mass by using Bragg pulses, an effective external  
electromagnetic coupling and an internal interaction, also covariant.

Finally I consider the 2D limit, describing the emergence of (2+1)  
Dirac fermions in presence of a strongly anisotropic lattice.
