Abstract:
We discuss quantum electrodynamics emerging in the vacua with
anisotropic scaling. Systems with anisotropic scaling were
suggested by Hořava in relation to the quantum theory of
gravity. In such vacua the space and time are not equivalent, and
moreover they obey different scaling laws, called the anisotropic
scaling. Such anisotropic scaling takes place for fermions in
bilayer graphene, where if one neglects the trigonal warping
effects the massless Dirac fermions have quadratic dispersion.
This results in the anisotropic quantum electrodynamics, in which
electric and magnetic fields obey different scaling laws. Here we
discuss the Heisenberg–Euler action and Schwinger pair production
in such anisotropic QED.
