The open supersymmetric Haldane-Shastry spin chain and its associated motifs
Jose Carrasco, Federico Finkel, Artemio González-López +1
We study the open version of the su supersymmetric Haldane-Shastry spin chain associated to the extended root system. We first evaluate the model's partition function…
New computable entanglement monotones from formal group theory
José A. Carrasco, Giuseppe Marmo, Piergiulio Tempesta
We present a mathematical construction of new quantum information measures that generalize the notion of logarithmic negativity. Our approach is based on formal group theory. We sh…
Jastrow-like ground states for quantum many-body potentials with near-neighbors interactions
Marzieh Baradaran, Jose A. Carrasco, Federico Finkel +1
We completely solve the problem of classifying all one-dimensional quantum potentials with nearest- and next-to-nearest-neighbors interactions whose ground state is Jastrow-like, i…
