Information diagrams in the study of entanglement in symmetric multi-quDit systems and applications to quantum phase transitions in Lipkin-Meshkov-Glick D-level atom models
Julio Guerrero, Alberto Mayorgas, Manuel Calixto
In this paper we pursue the use of information measures (in particular, information diagrams) for the study of entanglement in symmetric multi-quDit systems. We use generalizations…

Entanglement and U(D)-spin squeezing in symmetric multi-quDit systems and applications to quantum phase transitions in Lipkin-Meshkov-Glick D-level atom models
Manuel Calixto, Alberto Mayorgas, Julio Guerrero
Collective spin operators for symmetric multi-quDit (namely, identical -level atom) systems generate a U symmetry. We explore generalizations to arbitrary of SU(2)-spin…

Role of mixed permutation symmetry sectors in the thermodynamic limit of critical three-level Lipkin-Meshkov-Glick atom models
M. Calixto, A. Mayorgas, J. Guerrero
We introduce the notion of Mixed Symmetry Quantum Phase Transition (MSQPT) as singularities in the transformation of the lowest-energy state properties of a system of identical par…
