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 recent progress concerning extensions to quantum field theory and relativity. In the last section, I speculate about an extension of Bohmian mechanics to quantum gravity. 

What you always wanted to know about Bohmian mechanics but were afraid to ask

Bohmian mechanics is an alternative interpretation of quantum mechanics. We outline the main characteristics of its non-relativistic formulation. Most notably it does provide a simple solution to the

What Is Bohmian Mechanics

Bohmian mechanics is a quantum theory with a clear ontology and the status and the role of of the quantum formalism is clarified.

Quantum Mechanics and Ontology

This chapter considers the prospects, in the present state of research in quantum mechanics, for an ontological foundation for the theory that is compatible with the minimal constraints of scientific

A Dynamic Histories Interpretation of Quantum Theory

The problem of how to interpret quantum mechanics has persisted for a century. The disconnect between the wavefunction state vector and what is observed in experimental apparati has had no shortage

Bohmian Trajectories as the Foundation of Quantum Mechanics

Bohmian trajectories have been used for various purposes, including the numer- ical simulation of the time-dependent Schrodinger equation and the visualization of time-dependent wave functions. We

Quantum states for primitive ontologists

Under so-called primitive ontology approaches, in fully describing the history of a quantum system, one thereby attributes interesting properties to regions of spacetime. Primitive ontology

No-Collapse Interpretations of Quantum Theory

In Sect. 2.3.1, the measurement problem was formulated in the form of a trilemma. In this view, either (i) the wavefunction is not a complete description; or (ii) the time evolution is not a

Consequences of a Two-Time Relativistic Bohmian Model

Effects of a Bohmian quantum-relativistic theory are explored. The model is obtained by introducing a new and independent time parameter whose relative motions are not directly observable and cause

Pilot-wave approaches to quantum field theory

The purpose of this paper is to present an overview of recent work on pilot-wave approaches to quantum field theory. In such approaches, systems are not only described by their wave function, as in

Pilot Wave Theory and Quantum Fields

Pilot wave theory (PWT), also called de Broglie-Bohm theory or Bohmian Mechanics, is a deterministic nonlocal `hidden variables' quantum theory without fundamental uncertainty. It is in agreement



Bohmian mechanics and quantum field theory.

A recently proposed extension of Bohmian mechanics to quantum field theory is discussed, which describes explicit creation and annihilation events of particles: the world lines for the particles can begin and end.

Quantum Theory without Observers—Part One

Since its inception some 70 years ago and despite its extraordinary predictive successes, quantum mechanics has been plagued by conceptual difficulties. Plainly put, the basic problem is this: It is

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

Quantum Mechanics without “The Observer”

This thesis is that the observer, or better, the experimentalist, plays in quantum theory exactly the same role as in classical physics.

Comments on an Article of Takabayasi conserning the Formulation of Quantum Mechanics with Classical Pictures

Certain of Takabayasi's criticisms of a causal re·interpretation of the quantum theory are answered in detail. It is indicated .how this interpretation can be extended to the Dirac equation, and the

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 survey of Bohmian mechanics

SummaryBohmian mechanics is 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

An interpretation of quantum mechanics in terms of classical concepts, «beables,» due to de Broglie, Bohm, and Bell (BBB) is generalized and further developed and it is shown that, in the continuum limit, this interpretation reduces to the causal one of Bohm.

On the Problem of Hidden Variables in Quantum Mechanics

The demonstrations of von Neumann and others, that quantum mechanics does not permit a hidden variable interpretation, are reconsidered. It is shown that their essential axioms are unreasonable. It
