Within quantum chemistry, the electron clouds that surround nuclei in atoms and molecules are sometimes treated as clouds of probability and sometimes as clouds of charge. These two roles, tracing back to Schrödinger and Born, are in tension with one another but are not incompatible. Schrödinger’s idea that the nucleus of an atom is surrounded by a...

An Aristotelian philosophy of nature rejects the modern prejudice in favor of the microscopic, a rejection that is crucial if we are to penetrate the mysteries of the quantum world. I defend an Aristotelian model by drawing on both quantum chemistry and recent work on the measurement problem. By building on the work of Hans Primas, using the distin...

Our epistemic limits depend on the nature of the physical world we inhabit and the ways in which we can observe and manipulate it. This dissertation examines these limits in the realm of physical computation. It focuses on quantum computing and particularly computing in GRW quantum mechanics, although it has implications for both quantum computing ...

•The Schroedinger–Newton (SN) equations are pointed out to have two fatal problems.•We combine the SN equations with GRW collapse dynamics to create “GRWmN”.•GRWmN does not have the two fatal problems and is consistent with experiments.•GRWmN has two possible routes to being tested in future laboratory experiments.•GRWmN is suggested to have a viab...

This paper argues that ontic structural realism (OSR) faces a dilemma: either it remains on the general level of realism with respect to the structure of a given theory, but then it is, like epistemic structural realism, only a partial realism; or it is a complete realism, but then it has to answer the question how the structure of a given theory i...

We consider the relation between so called continuous localization models—i.e. non-linear stochastic Schrödinger evolutions—and the discrete GRW-model of wave function collapse. The former can be understood as scaling limit of the GRW process. The proof relies on a stochastic Trotter formula, which is of interest in its own right. Our Trotter formu...

The paper makes a case for there being causation in the form of causal properties or causal structures in the domain of fundamental physics. That case is built in the first place on an interpretation of quantum theory in terms of state reductions so that there really are both entangled states and classical properties, GRW being the most elaborate p...
