On the P-representable subset of all bipartite Gaussian separable states
M. C. de Oliveira
P-representability is a necessary and sufficient condition for separability of bipartite Gaussian states only for the special subset of states whose covariance matrix are $Sp(2,R)\…

Characterization and quantification of symmetric Gaussian state entanglement through a local classicality criterion
M. C. de Oliveira
A necessary and sufficient condition for characterization and quantification of entanglement of any bipartite Gaussian state belonging to a special symmetry class is given in terms…
