    "abstract": "We address nonlocality of a class of fully inseparable three-mode Gaussian\nstates generated either by bilinear three-mode Hamiltonians or by a sequence of\nbilinear two-mode Hamiltonians. Two different tests revealing strong\nnonlocality are considered, in which the dichotomic Bell operator is\nrepresented by displaced parity and by pseudospin operator respectively.\nThree-mode states are also considered as a conditional source of two-mode non\nGaussian states, whose nonlocal properties are analyzed. We found that the non\nGaussian character of the conditional states allows violation of Bell\u0027s\ninequalities (by parity and pseudospin tests) stronger than with a conventional\ntwin-beam state. However, the non Gaussian character is not sufficient to\nreveal nonlocality thorough a dichotomized quadrature measurement strategy.",
