dc.descriptionTo investigate spin dimerization in the t-J model we consider the extended t-J-δmodel with explicit spin dimerization introduced via parameter δ. At zero doping the dimerized spin liquid is unstable at δ< δ_c = 0.3. We demonstrate that the doping stabilizes the dimerized stripe phase: the δ_c(x) decreases when doping x increases. At doping larger than critical, x > x_c, the dimerized phase is stable even without explicit dimerization, i.e. at δ=0.
