Localization measures of parity adapted U()-spin coherent states applied to the phase space analysis of the -level Lipkin-Meshkov-Glick model
Alberto Mayorgas, Julio Guerrero, Manuel Calixto
We study phase-space properties of critical, parity symmetric, -quDit systems undergoing a quantum phase transition (QPT) in the thermodynamic limit. The leve…
Schmidt decomposition of parity adapted coherent states for symmetric multi-quDits
Julio Guerrero, Antonio Sojo, Alberto Mayorgas +1
In this paper we study the entanglement in symmetric -quDit systems. In particular we use generalizations to of spin coherent states and their projections on defin…
Stochastic Local Volatility models and the Wei-Norman factorization method
Julio Guerrero, Giuseppe Orlando
In this paper, we show that a time-dependent local stochastic volatility (SLV) model can be reduced to a system of autonomous PDEs that can be solved using the Heat kernel, by mean…
Coherent States for infinite homogeneous waveguide arrays: Cauchy coherent states for
Julio Guerrero, Francisco F. López-Ruiz
Perelomov coherent states for equally spaced, infinite homogeneous waveguide arrays with Euclidean E(2) symmetry are defined, and a new resolution of the identity is obtained. The…
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…
