Here I describe three systems in 3+1 dimensions that violate the boundary law for entanglement entropy.  The first is free Weyl fermions in a magnetic field, the second is a holographic strong coupling generalization of the Weyl fermion system, and the third is a strong topological insulator in the presence of dislocations.  These systems are unified by the presence of a low energy description that includes many gapless 1+1 dimensional modes.
