Generalized isotropic Lipkin-Meshkov-Glick models: ground state entanglement and quantum entropies
Jose A. Carrasco, Federico Finkel, Artemio Gonzalez-Lopez +2
We introduce a new class of generalized isotropic Lipkin-Meshkov-Glick models with su spin and long-range non-constant interactions, whose non-degenerate ground state is a D…
Integrable open spin chains related to infinite matrix product states
Bireswar Basu-Mallick, Federico Finkel, Artemio Gonzalez-Lopez
In this paper we study an su-invariant open version of the Haldane-Shastry spin chain whose ground state can be obtained from the chiral correlator of the free boson b…
Rational quantum integrable systems of D_N type with polarized spin reversal operators
B. Basu-Mallick, C. Datta, F. Finkel +1
We study the spin Calogero model of D_N type with polarized spin reversal operators, as well as its associated spin chain of Haldane-Shastry type, both in the antiferromagnetic and…
Yangian-invariant spin models and Fibonacci numbers
Federico Finkel, Artemio Gonzalez-Lopez
We study a wide class of finite-dimensional su(m|n)-supersymmetric models closely related to the representations of the Yangian Y(sl(m|n)) labeled by border strips. We quantitative…
