Broken translational symmetry in an emergent paramagnetic phase of graphene
We show that the spin-density wave state on the partially filled honeycomb and triangular lattices is preempted by a paramagnetic phase that breaks an emergent Z[subscript 4] symmetry of the system associated with the four inequivalent arrangements of spins in the quadrupled unit cell. Unlike other...
