Quantum melting of the long-range antiferromagnetic order and spin-wave condensation in t-J-V model

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/27126We 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.REVTEX 3.0, 8 pagesCondensed MatterQuantum melting of the long-range antiferromagnetic order and spin-wave condensation in t-J-V modeltext
