One way of obtaining a version of quantum mechanics without observers, and thus of solving the paradoxes of quantum mechanics, is to modify the Schrödinger evolution by implementing spontaneous collapses of the wave function. An explicit model of this kind was proposed in 1986 by Ghirardi, Rimini & Weber (GRW), involving a nonlinear, stochastic evolution of the wave function. We point out how, by focusing on the essential mathematical structure of the GRW model and a clear ontology, it can be… 
Collapse and Relativity
Ever since we have been in the possession of quantum theories without observers, such as Bohmian mechanics or the Ghirardi‐Rimini‐Weber (GRW) theory of spontaneous wave function collapse, a major
A Process Model of Non-Relativistic Quantum Mechanics
A process model of quantum mechanics utilizes a combinatorial game to generate a discrete and finite causal space I upon which can be defined a self-consistent quantum mechanics. An emergent
The ‘unromantic pictures’ of quantum theory
I am concerned with two views of quantum mechanics that John S Bell called ‘unromantic’: spontaneous wavefunction collapse and Bohmian mechanics. I discuss some of their merits and report about
The Ghirardi–Rimini–Weber (GRW) theory is a physical theory that, when combined with a suitable ontology, provides an explanation of quantum mechanics. The so-called collapse of the wave function is
Quantum mechanics in multiply-connected spaces
We explain why, in a configuration space that is multiply connected, i.e., whose fundamental group is nontrivial, there are several quantum theories, corresponding to different choices of topological

Wavefunctions and Minkowski Space-Time On the Reconciliation of Quantum Theory with Special Relativity
The implications of the relativistic space-time structure for a physical description by quantum mechanical wave-functions are investigated. On the basis of a detailed analysis of Bell's concept of
Relativistic Model for Gravity-Induced Quantum State Reduction
A Lorentz invariant model for gravity-induced quantum state reduction is presented, which is mainly developed from Penrose's argument that the time translation operator in a superposition of
Interpretations of Quantum Theory in the Light of Modern Cosmology
The difficult issues related to the interpretation of quantum mechanics and, in particular, the “measurement problem” are revisited using as motivation the process of generation of structure from
Parameter diagrams of the GRW and CSL theories of wavefunction collapse
It has been hypothesized that the time evolution of wavefunctions might include collapses, rather than being governed by the Schrödinger equation. The leading models of such an evolution,


Explicit wavefunction collapse and quantum measurement
In this thesis, we are concerned with models of explicit wavefunction collapse as a possible solution to the measurement problem of quantum mechanics. We examine the models where collapse is to
Quantum Equilibrium and the Role of Operators as Observables in Quantum Theory
Bohmian mechanics is arguably the most naively obvious embedding imaginable of Schrödinger's equation into a completely coherent physical theory. It describes a world in which particles move in a
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
Spontaneous Collapse Models on a Lattice
We present spontaneous collapse models of field theories on a 1+1 null lattice, in which the causal structure of the lattice plays a central role. Issues such as “locality,” “nonlocality,” and
A Proposed Solution of the Measurement Problem in Quantum Mechanics by a Hidden Variable Theory
The measurement problem in quantum mechanics is re-examined and it is shown that it cannot really be solved in a satisfactory way, within the framework of the usual interpretation of the theory. We

A linear equation of motion for the state vector is presented, in which an anti-Hermitian Hamiltonian that fluctuates randomly is added to the usual Hamiltonian of the Schr\"odinger equation. It is
Markov processes in Hilbert space and continuous spontaneous localization of systems of identical particles.
Stochastic differential equations describing the Markovian evolution of state vectors in the quantum Hilbert space are studied as possible expressions of a universal dynamical principle and the stochastic evolution is proved to induce continuous dynamical reduction of the state vector onto mutually orthogonal subspaces.
A Relativistic Version of the Ghirardi–Rimini–Weber Model
Carrying out a research program outlined by John S. Bell in 1987, we arrive at a relativistic version of the Ghirardi-Rimini-Weber (GRW) model of spontaneous wavefunction collapse. The GRW model was
On the Common Structure of Bohmian Mechanics and the Ghirardi–Rimini–Weber Theory
Bohmian mechanics and the Ghirardi–Rimini–Weber theory provide opposite resolutions of the quantum measurement problem: the former postulates additional variables (the particle positions) besides the
