Localization for Dirac fermions
Aleksander M. Kubicki, Hans Westman, Juan Leon
This work is devoted to incorporating into QFT the notion that particles and hence the particle states should be localizable in space. It focuses on the case of the Dirac field in…
A first-order approach to conformal gravity
T. G. Zlosnik, H. F. Westman
We investigate whether a spontaneously-broken gauge theory of the group may be a genuine competitor to General Relativity. The basic ingredients of the theory are an $SU(…
An introduction to the physics of Cartan gravity
H. F. Westman, T. G. Zlosnik
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-geomet…
What does it mean for half of an empty cavity to be full?
Eric G. Brown, Marco del Rey, Hans Westman +2
It is well known that the vacuum state of a quantum field is spatially entangled. This is true both in free and confined spaces, for example in an optical cavity. The obvious conse…
Local quanta, unitary inequivalence, and vacuum entanglement
Matias Rodriguez-Vazquez, Marco del Rey, Hans Westman +1
In this work we develop a formalism for describing localised quanta for a real-valued Klein-Gordon field in a one-dimensional box . We quantise the field using non-stationa…
Cosmological signature change in Cartan Gravity with dynamical symmetry breaking
Joao Magueijo, Matias Rodriguez-Vazquez, Hans Westman +1
We investigate the possibility for classical metric signature change in a straightforward generalization of the first order formulation of gravity, dubbed "Cartan gravity". The mat…
