    Relativistic Spontaneous Localization: A Proposal. [REVIEW]Oreste Nicrosini & Alberto Rimini - 2003 - Foundations of Physics 33 (7):1061-1084.
    A new proposal for a Lorentz-invariant spontaneous localization process in the framework of relativistic quantum field theory is presented. As in all dynamical reduction models, a stochastic process is introduced, which drives the state vector towards the eigenspaces of a set of operators representing suitably chosen physical quantities. Such operators constitute a Lorentz scalar field and are built as time averages and space integrals of a local field-theoretic operator in such a way that the quantities they represent acquire a macroscopic (...)

    Compoundation Invariance and Bohmian Mechanics.Giulio Peruzzi & Alberto Rimini - 2000 - Foundations of Physics 30 (9):1445-1472.
    The property of fundamental mechanical theories which allows to treat compound objects as particles under suitable conditions is considered. It is argued that such a property, called compoundation invariance, is a nonreleasable property of any mechanical theory not declaring to which elementary constituents it applies. Compoundation invariance is discussed in the framework of Bohmian mechanics. It is found that standard Bohmian mechanics satisfies the requirement of compoundation invariance, with some reservation in the case of compound objects with spin. On the (...)

    On the Relationship Between Continuous and Discontinuous Stochastic Processes in Hilbert Space.Oreste Nicrosini & Alberto Rimini - 1990 - Foundations of Physics 20 (11):1317-1327.
    Two different kinds of stochastic processes in Hilbert space used to introduce spontaneous localization into the quantum evolution are investigated. In the processes of the first type, finite changes of the wave function take place instantaneously with a given mean frequency. The processes of the second type are continuous. It is shown that under a suitable infinite frequency limit the discontinuous process transforms itself into the continuous one.

    On the Existence of Inequivalent Quasideterministic Domains.Irene Giardina & Alberto Rimini - 1996 - Foundations of Physics 26 (8):973-987.
    In the framework of the history approach to quantum mechanics and, in particular, of the formulation of Gell-Mann and Hartle, the question of the existence of inequivalent decoherent sets of histories is reconsidered. A simple but acceptably realistic model of the dynamics of the universe is proposed and a particular set of histories is shown to be decoherent. By suitable tranformations of this set, a family of sets of histories is then generated, such that the sets, first, are decoherent on (...)

    Compound Objects as Particles in Quantum Mechanics.Alberto Rimini - 1997 - Foundations of Physics 27 (12):1689-1699.
    The property of fundamental mechanical theories which allows one to treat compound objects as particles under suitable conditions is considered. It is argued that such a property, called composition invariance, is a nonreleasable property of any fundamental mechanical theory. The proof that standard quantum mechanics enjoys composition invariance is reviewed. Finally, it is shown that the requirement of composition invariance allows one to choose between two alternative forms of quantum mechanics with spontaneous localization.
