A Haldane–Shastry spin chain of BCN type in a constant magnetic field
نویسنده
چکیده
We compute the spectrum of the trigonometric Sutherland spin model of BCN type in the presence of a constant magnetic field. Using Polychronakos’s freezing trick, we derive an exact formula for the partition function of its associated Haldane–Shastry spin chain.

Integrable 1/r Spin Chain with Reflecting End
A new integrable spin chain of the Haldane-Shastry type is introduced. It is interpreted as the inverse-square interacting spin chain with a reflecting end. The lattice points of this model consist of the square of the zeros of the Laguerre polynomial. Using the “exchange operator formalism”, the integrals of motion for the model are explicitly constructed. Typeset using REVTEX ∗E-mail address ...
متن کاملPhysics of the Ideal Semion Gas: Spinons and Quantum Symmetries of the Integrable Haldane-shastry Spin Chain
Various aspects of the Haldane-Shastry spin chain with 1/r 2 exchange, and its various generalizations, are reviewed, with emphasis on its Yangian quantum group structure, and the interpretation of the model as the generalization of an ideal gas (of " spinons ") to the case of fractional statistics. Some recent results on its dynamical correlation function are discussed, and conjectured extensi...
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...

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 کاملThe trigonometric counterpart of the Haldane Shastry Model
The hierarchy of Integrable Spin Chain Hamiltonians, which are trigonometric analogs of the Haldane Shastry Model and the associated higher conserved charges, is derived by a reduction from the trigonometric Dynamical Models of Bernard-Gaudin-Haldane-Pasquier. The Spin Chain Hamiltonians have the property of U ′ q(ĝl2)-invariance. The spectrum of the Hamiltonians and the U ′ q(ĝl2)-representati...
