Spin chains from dynamical quadratic algebras
نویسندگان
چکیده
We present a construction of integrable quantum spin chains where local spin-spin interactions are weighted by “position”-dependent potential containing abelian non-local spin dependance. This construction applies to the previously defined three general quadratic reflection-type algebras: respectively non-dynamical, semidynamical, fully dynamical. e-mail: [email protected] e-mail: [email protected]

We propose a dynamical matrix product ansatz describing the stochastic dynamics of two species of particles with excluded-volume interaction and the quantum mechanics of the associated quantum spin chains respectively. The time-dependent algebra which is obtained from the action of the Markov generator of the exclusion process (or quantum Hamiltonian of the spin chain respectively) is given in ...
متن کاملC∗-Algebras Associated with Quadratic Dynamical System
In this paper we consider enveloping C *-algebras of *-algebras given by generators and defining relations of the following form A = CX, X * | XX * = f (X * X), where f is a Hermitian mapping. Some properties of these algebras associated with simple dynamical systems (f, R) are studied. As an example quadratic dynamical systems are considered.
