Dynamical origin of quantum probabilities
We study the origin of the Born probability rule ρ = |ψ|2 in the de Broglie–Bohm pilot–wave formulation of quantum theory. It is argued that quantum probabilities arise dynamically, and have a statusExpand

Coordinates, observables and symmetry in relativity
We investigate the interplay and connections between symmetry properties of equations, the interpretation of coordinates, the construction of observables, and the existence of physical relativityExpand

SIGGRAPH Asia
Asia is rising. While Japan has been dominant economically for decades, China and India are growing at a phenomenal rate, and the four Asian tigers, Hong Kong, Korea, Singapore and Taiwan are stillExpand

WKB analysis of relativistic Stern-Gerlach measurements
Abstract Spin is an important quantum degree of freedom in relativistic quantum information theory. This paper provides a first-principles derivation of the observable corresponding to aExpand

A minimalist pilot-wave model for quantum electrodynamics
We present a way to construct a pilot-wave model for quantum electrodynamics. The idea is to introduce beables corresponding only to the bosonic and not to the fermionic degrees of freedom of theExpand

Events and Observables in Generally Invariant Spacetime Theories
We address the problem of observables in generally invariant spacetime theories such as Einstein’s general relativity. Using the refined notion of an event as a “point-coincidence” between scalarExpand

Local quanta, unitary inequivalence, and vacuum entanglement
In this work we develop a formalism for describing localised quanta for a real-valued Klein-Gordon eld in a one-dimensional box [0 ;R]. We quantise the eld using non-stationary local modes which, atExpand

An introduction to the physics of Cartan gravity
A distance can be measured by monitoring how much a wheel has rotated when rolled without slipping. This simple idea underlies the mathematics of Cartan geometry. The Cartan-geometric description ofExpand

A first-order approach to conformal gravity
We investigate whether a spontaneously-broken gauge theory of the group $SU(2,2)$ may be a genuine competitor to General Relativity. The basic ingredients of the theory are an $SU(2,2)$ gauge fieldExpand

Gravity, Cartan geometry, and idealized waywisers
The primary aim of this paper is to provide a simple and concrete interpretation of Cartan geometry in terms of the mathematics of idealized waywisers. Waywisers, also called hodometers, areExpand
