Spontaneous spin stripe dimerization in the doped t-J model
O. P. Sushkov
To 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…

Superconducting pairing, and the collective magnetic excitation in the extended 2-dimensional t-J model
Oleg Sushkov
To investigate the non-Fermi liquid behavior we consider the extended two-dimensional t-J model which includes additional hopping t''. In the regime t,J << t'' we were able to solv…
