Violations of locality and free choice are equivalent resources in Bell experiments
Pawel Blasiak, Emmanuel M. Pothos, James M. Yearsley +2
Bell inequalities rest on three fundamental assumptions: realism, locality, and free choice, which lead to nontrivial constraints on correlations in very simple experiments. If we…
Contextuality in Human Decision Making in the Presence of Direct Influences: A Comment on Basieva et al. (2019)
James M Yearsley, Jonathan J Halliwell
In a recent paper Basieva, Cervantes, Dzhafarov, and Khrennikov (2019) presented a series of experiments which they claimed show evidence for contextuality in human judgments. This…
Amplitudes for Spacetime Regions and the Quantum Zeno Effect: Pitfalls of Standard Path Integral Constructions
J. J. Halliwell, J. M. Yearsley
We argue that under very general conditions, there is a significant complication in amplitudes for spacetimes regions constructed from path integrals. This is the fact that the con…
Pitfalls of Path Integrals: Amplitudes for Spacetime Regions and the Quantum Zeno Effect
J. J. Halliwell, J. M. Yearsley
Path integrals appear to offer natural and intuitively appealing methods for defining quantum-mechanical amplitudes for questions involving spacetime regions. For example, the ampl…
Aspects of Time in Quantum Theory
James M Yearsley
We consider a number of aspects of the problem of defining time observables in quantum theory. Time observables are interesting quantities in quantum theory because they often cann…
Quantum Arrival and Dwell Times via Idealised Clocks
J. M. Yearsley, D. A. Downs, J. J. Halliwell +1
A number of approaches to the problem of defining arrival and dwell time probabilities in quantum theory make use of idealised models of clocks. An interesting question is the exte…
A review of the decoherent histories approach to the arrival time problem in quantum theory
James M Yearsley
We review recent progress in understanding the arrival time problem in quantum mechanics, from the point of view of the decoherent histories approach to quantum theory. We begin by…
On the Relationship Between Complex Potentials and Strings of Projection Operators
J. J. Halliwell, J. M. Yearsley
It is of interest in a variety of contexts, and in particular in the arrival time problem, to consider the quantum state obtained through unitary evolution of an initial state regu…
Quantum Arrival Time For Open Systems
J. M. Yearsley
We extend previous work on the arrival time problem in quantum mechanics, in the framework of decoherent histories, to the case of a particle coupled to an environment. The usual a…
The propagator for the step potential using the path decomposition expansion
James M. Yearsley
We present a direct path integral derivation of the propagator in the presence of a step potential. The derivation makes use of the Path Decomposition Expansion (PDX), and also of…
The propagator for the step potential and delta function potential using the path decomposition expansion
James M. Yearsley
We present a derivation of the propagator for a particle in the presence of the step and delta function potentials. These propagators are known, but we present a direct path integr…
