Exactly solvable deformations of the oscillator and Coulomb systems and their generalization
Angel Ballesteros, Alberto Enciso, Francisco J. Herranz +2
We present two maximally superintegrable Hamiltonian systems and that are defined, respectively, on an -dimensional spherically symmetric generalizatio…
A maximally superintegrable deformation of the N-dimensional quantum Kepler-Coulomb system
Angel Ballesteros, Alberto Enciso, Francisco J. Herranz +2
The -dimensional quantum Hamiltonian is shown to be exa…
Thermodynamics of spin chains of Haldane-Shastry type and one-dimensional vertex models
A. Enciso, F. Finkel, A. Gonzalez-Lopez
We study the thermodynamic properties of spin chains of Haldane-Shastry type associated with the A_{N-1} root system in the presence of a uniform external magnetic field. To this e…
Superintegrable potentials on 3D Riemannian and Lorentzian spaces with non-constant curvature
Angel Ballesteros, Alberto Enciso, Francisco J. Herranz +1
A quantum sl(2,R) coalgebra is shown to underly the construction of a large class of superintegrable potentials on 3D curved spaces, that include the non-constant curvature analogu…
A novel quasi-exactly solvable spin chain with nearest-neighbors interactions
A. Enciso, F. Finkel, A. Gonzalez-Lopez +1
In this paper we study a novel spin chain with nearest-neighbors interactions depending on the sites coordinates, which in some sense is intermediate between the Heisenberg chain a…
Exchange operator formalism for N-body spin models with near-neighbors interactions
A. Enciso, F. Finkel, A. Gonzalez-Lopez +1
We present a detailed analysis of the spin models with near-neighbors interactions constructed in our previous paper [Phys. Lett. B 605 (2005) 214] by a suitable generalization of…
