Quantum melting of the long-range antiferromagnetic order and spin-wave condensation in t-J-V model
arXiv:cond-mat/9406105
Abstract
We consider two-dimensional t-J-V model. The wave function of the ground state is constructed. We demonstrate that the doping by holes results in condensation of the spin-waves, destruction of the long-range antiferromagnetic order and formation of the gap in the spin-wave spectrum.
