Emergence of particles from bosonic quantum field theory
David Wallace
An examination is made of the way in which particles emerge from linear, bosonic, massive quantum field theories. Two different constructions of the one-particle subspace of such t…
In defence of naivete: The conceptual status of Lagrangian QFT
David Wallace
I analyse the conceptual and mathematical foundations of Lagrangian quantum field theory (that is, the "naive" quantum field theory used in mainstream physics, as opposed to algebr…
Everett and Structure
David Wallace
I address the problem of indefiniteness in quantum mechanics: the problem that the theory, without changes to its formalism, seems to predict that macroscopic quantities have no de…
Worlds in the Everett Interpretation
David Wallace
This is a discussion of how we can understand the world-view given to us by the Everett interpretation of quantum mechanics, and in particular the role played by the concept of `wo…
Quantum Interrogation and the Safer X-ray
Adrian Kent, David Wallace
We investigate quantum interrogation techniques which allow imaging information about semi-transparent objects to be obtained with lower absorption rates than standard classical me…
