Two kinds of possible dimerization patterns of Spin-Peierls transition in a 2D spin-1/2 Heisenberg model antiferromagnetic coupled to bond phonons with variable inter-chain coupling strength, corresponding to wave vectors Q=(π,0) andQ=(π,π), are investigated by using the Stochastic Series Expansion...
