Generalized conditional entropy optimization for qudit-qubit states
N. Gigena, R. Rossignoli
We derive a general approximate solution to the problem of minimizing the conditional entropy of a qudit-qubit system resulting from a local projective measurement on the qubit, wh…

Generalized mean field description of entanglement in dimerized spin systems
A. Boette, R. Rossignoli, N. Canosa +1
We discuss a generalized self-consistent mean field (MF) treatment, based on the selection of an arbitrary subset of operators for representing the system density matrix, and its a…

Dynamics of entanglement between two harmonic modes in stable and unstable regimes
L. Rebón, N. Canosa, R. Rossignoli
The exact dynamics of the entanglement between two harmonic modes generated by an angular momentum coupling is examined. Such system arises when considering a particle in a rotatin…
