Functionally independent conservations laws in a quantum integrable model
Haile Owusu, B. Sriram Shastry
We study a recently proposed quantum integrable model defined on a lattice with N sites, with Fermions or Bosons populating each site, as a close relative of the well known spin-1/…

Classification of Parameter-Dependent Quantum Integrable Models, Their Parameterization, Exact Solution, and Other Properties
Haile K. Owusu, Emil A. Yuzbashyan
We study general quantum integrable Hamiltonians linear in a coupling constant and represented by finite NxN real symmetric matrices. The restriction on the coupling dependence lea…

The Link between Integrability, Level Crossings, and Exact Solution in Quantum Models
H. K. Owusu, K. Wagh, E. A. Yuzbashyan
We investigate the connection between energy level crossings in integrable systems and their integrability, i.e. the existence of a set of non-trivial integrals of motion. In parti…
