A Unified Treatment for XXX-Heisenberg Model and Haldane-Shastry Model Using Shift Operators
نویسندگان
چکیده
A unified treatment is developed for the XXX-Heisenberg model and a long-ranged interaction model (the H2 in Haldane-Shastry model) from the point of view of shift operators (or raising and lowering operators), based on which the energy spectra of the spin-chain models are determined. Some physical discussions are also made. PACS numbers: 75.10.Jm, 03.65.Fd

The conformal limit over an anti-ferromagnetic vacuum of the fermionic spin 1 2 Calogero-Sutherland Model is derived by using the wedge product formalism. The space of states in the conformal limit is identified with the Fock space of two complex fermions, or, equivalently, with a tensor product of an irreducible level-1 module of ŝl2 and a Fock space module of the Heisenberg algebra. The Hamil...
متن کاملHaldane – Shastry spin chains of BC N type
We introduce four types of SU(2M + 1) spin chains which can be regarded as the BC N versions of the celebrated Haldane–Shastry chain. These chains depend on two free parameters and, unlike the original Haldane–Shastry chain, their sites need not be equally spaced. We prove that all four chains are solvable by deriving an exact expression for their partition function using Polychronakos's " free...
متن کاملInvariants of the Haldane-Shastry SU(N) chain.
Using a formalism developed by Polychronakos, we explicitly construct a set of invariants of the motion for the Haldane-Shastry SU(N) chain. Submitted to Physical Review Letters, PACS numbers: 75.10.Jm, 05.30.-d, 03.65.Ca † [email protected] ‡ [email protected] There have been several recent papers on the Haldane-Shastry model for spin chains and its SU(N) generalizat...
متن کاملThermal negativity in a two qubit XXX and XX spin chain model in an external magnetic field
In this paper we studied the thermal negativity in a two-qubit XX spin ½ chain model and XXX spin1/2 chain model(isotropic Heisenberg model)spin-1/2 chain subjected to an external magnetic field inz direction. We calculate analytical relation for the thermal negativity for two qubit XX and XXX spinchain models in the external magnetic field. Effects of the magnetic field and temperature on then...
متن کاملLattice integrable systems of Haldane-Shastry type.
We present a new lattice integrable system in one dimension of the Haldane-Shastry type. It consists of spins positioned at the static equilibrium positions of particles in a corresponding classical Calogero system and interacting through an exchange term with strength inversely proportional to the square of their distance. We achieve this by viewing the Haldane-Shastry system as a high-interac...
