We study a model of spontaneous wavefunction collapse for a free quantum particle. We analyse in detail the time evolution of the single-Gaussian solution and the double-Gaussian solution, showing how the reduction mechanism induces the localization of the wavefunction in space; we also study the asymptotic behaviour of the general solution. With an appropriate choice for the parameter λ which sets the strength of the collapse mechanism we prove that: (i) the effects of the reducing terms on…

Non-Markovian dynamics for a free quantum particle subject to spontaneous collapse in space: General solution and main properties
We analyze the non-Markovian dynamics of a quantum system subject to spontaneous collapse in space. After having proved, under suitable conditions, the separation of the center-of-mass and relative
The quantum theory of measurement within dynamical reduction models
We analyse in mathematical detail, within the framework of the QMUPL model of spontaneous wavefunction collapse, the von Neumann measurement scheme for the measurement of a 1/2 spin particle. We
Collapse models with non-white noises
We set up a general formalism for models of spontaneous wavefunction collapse with dynamics represented by a stochastic differential equation driven by general Gaussian noises, not necessarily white
On the energy increase in space-collapse models
A typical feature of spontaneous collapse models which aim at localizing wavefunctions in space is the violation of the principle of energy conservation. In the models proposed in the literature, the
On the electromagnetic properties of matter in collapse models
We discuss the electromagnetic properties of both a charged free particle, and a charged particle bounded by an harmonic potential, within collapse models. By choosing a particularly simple—yet
On the long time behavior of free stochastic Schrödinger evolutions
We discuss the time evolution of the wave function which is the solution of a stochastic Schrodinger equation describing the dynamics of a free quantum particle subject to spontaneous localizations
Collapse models with non-white noises: II. Particle-density coupled noises
We continue the analysis of models of spontaneous wavefunction collapse with stochastic dynamics driven by non-white Gaussian noise. We specialize to a model in which a classical ‘noise’ field, with
Bohmian mechanics, collapse models and the emergence of classicality
We discuss the emergence of classical trajectories in Bohmian mechanics, when a macroscopic object interacts with an external environment. We show that in such a case the conditional wave function of
Non-markovian quantum trajectories: an exact result.
For the first time, the explicit general solution for the free particle case (H=p(2)/2m) is given and the main properties are discussed.
Dissipative collapse models with nonwhite noises
We study the generalization of the QMUPL model which accounts both for memory and dissipative effects. This is the first model where both features are combined. After having derived the non-local


Wavefunction Collapse and Random Walk
Wavefunction collapse models modify Schrödinger's equation so that it describes the rapid evolution of a superposition of macroscopically distinguishable states to one of them. This provides a
The emergence of classical properties through interaction with the environment
The dependence of macroscopic systems upon their environment is studied under the assumption that quantum theory is universally valid. In particular scattering of photons and molecules turns out to
Generalized stochastic Schrödinger equations for state vector collapse
A number of authors have proposed stochastic versions of the Schrodinger equation, either as effective evolution equations for open quantum systems or as alternative theories with an intrinsic
Describing the macroscopic world: Closing the circle within the dynamical reduction program
With reference to recently proposed theoretical models accounting for reduction in terms of a unified dynamics governing all physical processes, we analyze the problem of working out a worldview
Unified dynamics for microscopic and macroscopic systems.
A modified quantum dynamics for the description of macroscopic objects is constructed and it is shown that it forbids the occurrence of linear superpositions of states localized in far-away spatial regions and induces an evolution agreeing with classical mechanics.
The quantum-state diffusion model applied to open systems
A model of a quantum system interacting with its environment is proposed in which the system is represented by a state vector that satisfies a stochastic differential equation, derived from a density

A master equation with a Lindblad structure is derived, which describes the interaction of a test particle with a macroscopic system and is expressed in terms of the operator valued dynamic structure
Quantum state diffusion, density matrix diagonalization, and decoherent histories: A model.
The quantum evolution of a particle moving in a potential in interaction with an environment of harmonic oscillators in a thermal state is analysed, using the quantum state diffusion (QSD) picture of Gisin and Percival, to exemplify the general connection between the QSD picture and the decoherent histories approach to quantum mechanics.
