Двовимiрна спiн-1/2 J1 − J′1 − J2 модель Гайзенберґа в рамках перетворення Йордана–Вiґнера
The Jordan–Wigner transformation is applied to the spatially anisotropic spin-1/2 Heisenberg model on a square lattice with the nearest-neighbor and next-nearest-neighbor antiferromagnetic interactions. The transformed Hamiltonian describes the interacting spinless fermions that hop between neighbor...
