Neel to staggered dimer order transition in a generalized honeycomb lattice Heisenberg model
Argha Banerjee, Kedar Damle, Arun Paramekanti
We study a generalized honeycomb lattice spin-1/2 Heisenberg model with nearest-neighbor antiferromagnetic 2-spin exchange, and competing 4-spin interactions which serve to stabili…
