Pilot Wave model that includes creation and annihilation of particles
The purpose of this paper is to come up with a Pilot Wave model of quantum
field theory that incorporates particle creation and annihilation without
sacrificing determinism. This has been previously attempted in an article by
the same author titled "Incorporating particle creation and annihilation in
Pilot Wave model", in a much less satisfactory way. In this paper I would like
to "clean up" some of the things. In particular, I would like to get rid of a
very unnatural concept of "visibility" of particles, which makes the model much
simpler. On the other hand, I would like to add a mechanism for decoherence,
which was absent in the previous version.Comment: 9 pages, no figure
Pilot wave model without configuration or Fock spaces
The goal of this article is to come up with interpretation of quantum
phenomena that is both local and deterministic. This is done by the means of
envoking two different metrics, and . These two metrics give very
different "speeds of light": and , respectively. The and
are, respectively, "ordinary" metric and speed of light that we are used to. On
the other hand, is superluminal. In this paper I propose a model in which
newly introduced signals, which are subject to , are responsible for key
quantum phenomena.Comment: 36 pages, no figure
Gauge Fields in Causal Set Theory
This is the second paper in a series on the dynamics of matter fields in the
causal set approach to quantum gravity. We start with the usual expression for
the Lagrangian of a charged scalar field coupled to a SU(n) Yang-Mills field,
in which the gauge field is represented by a connection form, and show how to
write it in terms of holonomies between pairs of points, causal relations, and
volumes or timelike distances, all of which have a natural correspondence in
the causal set context. In the second part of the paper we present an
alternative model, in which the gauge field appears as the result of a
procedure inspired by the Kaluza-Klein reduction in continuum field theory, and
the dynamics can be derived simply using the gravitational Lagrangian of the
theory.Comment: 11 pages, no figure
