New series of multi-parametric solutions to GYBE: Quantum gates and integrability

We obtain two series of spectral parameter dependent solutions to the generalized Yang-Baxter equations (GYBE), for definite types of N12×N22 matrices with general dimensions N1 and N2. Appropriate extensions are presented for the inhomogeneous GYBEs. The first series of the solutions includes as pa...

Description
Summary:We obtain two series of spectral parameter dependent solutions to the generalized Yang-Baxter equations (GYBE), for definite types of N12×N22 matrices with general dimensions N1 and N2. Appropriate extensions are presented for the inhomogeneous GYBEs. The first series of the solutions includes as particular cases the X-shaped trigonometric braiding matrices. For construction of the second series the colored and graded permutation operators are defined, and multi-spectral parameter Yang-Baxterization is performed. For some examples the corresponding integrable models are discussed. The unitary solutions existing in these two series can be considered as generalizations of the multipartite Bell matrices in the quantum information theory.
