Description
The study of the effect of rotation in strongly-interacting matter has drawn a lot of attention in the theoretical community, due to its relevance for heavy-ion collision experiments. Lattice simulations in the presence of rotation are commonly carried out by changing to a corotating frame, which amounts to modifying the metric. As a preparation for simulating QCD using this formalism, we study a system of non-interacting fermions in the presence of rotation on the lattice. We analyze the effect of different boundary conditions and discretizations of the fermion action in different observables, like the moments of inertia or the chiral condensate. As a main crosscheck, we study the Axial Vortical Effect (AVE), the axial current appearing in a rotating system at finite temperature, whose conductivity is analytically known for a non-interacting fermion system.
