Spin waves in antiferromagnetic spin chains with long-range interactions
We study antiferromagnetic spin chains with unfrustrated long-range interactions that decay as power laws with exponent b , using the spin-wave approximation. We find for sufficiently large spin S that the Neel order is stable at T50 for b,3, and survives up to a finite Neel temperature for b,2, validating the spin-wave approach in these regimes. We estimate the critical values of S and T for t...
متن کاملQuantum melting of the long - range antiferromagnetic order and spin - wave condensation in t − J − V model
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. PACS numbers: 71.27.+a, 74.20.Hi, 75.50.Ee It is well known that the long-range antiferromagnetic (AF) order ...
متن کاملFirst Order Transition in the Frustrated Antiferromagnetic Heisenberg S=1 Quantum Spin Chain.
We study a frustrated Heisenberg S 1 quantum spin chain with next-nearest neighbor (NNN) coupling a using a variational ansatz and the density matrix renormalization group. We find as quantum remnants of the phase transition in the classical chain a disorder point at a D 0.284͑1͒ and a Lifshitz point at a L 0.3725͑25͒. Our main finding is a first-order transition from an Affleck-Kennedy-Lieb-...
متن کاملLong - range spin - pairing order and spin defects in quantum spin - 1 2 ladders
For w-legged antiferromagnetic spin-1/2 Heisenberg ladders, a long-range spin pairing order can be identified which enables the separation of the space spanned by finite-range (covalent) valence-bond configurations into w + 1 subspaces. Since every subspace has an equivalent counter subspace connected by translational symmetry, twofold degeneracy, breaking translational symmetry is found except...
متن کاملNew Solutions for the Anisotropic Antiferromagnetic Chain
Coherent states are proposed as solutions for the antiferromagnetic Heisenberg Hamiltonian in the quasi-Ising asymptotic regime of high anisotropy. Since our solutions are given in closed analytical form, a deep insight concerning the structure of the ground state and its excitations is obtained. Our calculation is in excellent agreement with numerical simulations. It has been suggested that th...
