A brief review is given of the continuous spontaneous localization (CSL) model, in which a classical field interacts with quantized particles to cause dynamical wavefunction collapse. One of the model's predictions is that particles “spontaneously” gain energy at a slow rate. When applied to the excitation of a nucleon in a Ge nucleus, it is shown how a limit on the relative collapse rates of neutron and proton can be obtained, and a rough estimate is made from data. When applied to the… Expand
Wavefunction Collapse and Conservation Laws
It is emphasized that the collapse postulate of standard quantum theory can violate conservation of energy-momentum and there is no indication from where the energy-momentum comes or to where itExpand
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 aExpand
Collapse Models
This is a review of formalisms and models (nonrelativistic and relativistic) which modify Schrödinger’s equation so that it describes wavefunction collapse as a dynamical physical process. 1Expand
Chronogenesis, Cosmogenesis and Collapse
A simple quantum model describing the onset of time is presented. This is combined with a simple quantum model of the onset of space. A major purpose is to explore the interpretational issues whichExpand
Dark energy from quantum wave function collapse of dark matter
Abstract Dynamical wave function collapse models entail the continuous liberation of a specified rate of energy arising from the interaction of a fluctuating scalar field with the matter waveExpand
Completely quantized collapse and consequences
Promotion of quantum theory from a theory of measurement to a theory of reality requires an unambiguous specification of the ensemble of realizable states (and each state's probability ofExpand

Do We Really Understand Quantum Mechanics
This article presents a general discussion of several aspects of our present understanding of quantum mechanics. The emphasis is put on the very special correlations that this theory makes possible:Expand
Macroscopic quantum resonators in space
While quantum concepts like superposition and entanglement are frequently being confirmed in the lab, these concepts seem to be in blatant contradiction to our everyday experience. There, objects areExpand

TLDR
It is shown that the behavior of the first excited 0+ state cannot be obtained by a reasonable variation of parameters in the exact neutron pair calculations, and suggests that the model space be enlarged to include proton, neutron, and proton-neutron pairing. Expand

TLDR
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. Expand
