A First Principles Derivation of Classical and Quantum Mechanics as the Natural Theories for Smooth Stochastic Paths
Willem Westra
We derive the classical Hamilton-Jacobi equation from first principles as the natural description for smooth stochastic processes when one neglects stochastic velocity fluctuations…
A local induced action for the noncritical string
W. Westra, S. Zohren
We present an alternative to Polyakov's induced action for the noncritical string. Our Yang-Mills like action is both local and invariant under coordinate transformations. It defin…
A Causal Alternative to Feynman's Propagator
Jurjen F. Koksma, W. Westra
The Feynman propagator used in the conventional in-out formalism in quantum field theory is not a causal propagator as wave packets are propagated virtually instantaneously outside…
Localization of particles in quantum field theory
W. Westra
We put forward an interpretation of scalar quantum field theory as relativistic quantum mechanics by curing well known problems related to locality. A probabilistic interpretation…
Causal random geometry from stochastic quantization
J. Ambjorn, R. Loll, W. Westra +1
In this short note we review a recently found formulation of two-dimensional causal quantum gravity defined through Causal Dynamical Triangulations and stochastic quantization. Thi…
A tight Tsirelson inequality for infinitely many outcomes
S. Zohren, P. Reska, R. D. Gill +1
We present a novel tight bound on the quantum violations of the CGLMP inequality in the case of infinitely many outcomes. Like in the case of Tsirelson's inequality the proof of ou…
