Stochastic evolution as a quasiclassical limit of a boundary value problem for Schrödinger equations [PDF]

open access: yes, 2002
We develop systematically a new unifying approach to the analysis of linear stochastic, quantum stochastic and even deterministic equations in Banach spaces.

General boundary quantum field theory: Timelike hypersurfaces in the Klein-Gordon theory [PDF]

open access: yesPhysical Review D, 2006
We show that the real massive Klein-Gordon theory admits a description in terms of states on various timelike hypersurfaces and amplitudes associated to regions bounded by them. This realizes crucial elements of the general boundary framework for quantum field theory.

Boundary string current & Weyl anomaly in six-dimensional conformal field theory

open access: yesJournal of High Energy Physics, 2019
It was recently discovered that for a boundary system in the presence of a background magnetic field, the quantum fluctuation of the vacuum would create a non-uniform magnetization density for the vacuum and a magnetization current is induced in the ...

Are Rindler Quanta Real? Inequivalent Particle Concepts in Quantum Field Theory [PDF]

open access: yes, 2000
Philosophical reflection on quantum field theory has tended to focus on how it revises our conception of what a particle is. However, there has been relatively little discussion of the threat to the "reality" of particles posed by the possibility of ...

Perturbed conformal field theory, nonlinear integral equations and spectral problems [PDF]

open access: yes, 2000
This thesis is concerned with various aspects of perturbed conformal field theory and the methods used to calculate finite-size effects of integrable quantum field theories.

SPACETIME OR QUANTUM PARTICLES: THE ONTOLOGY OF QUANTUM GRAVITY? [PDF]

open access: yes, 1996
The domains of quantum theory and general relativity overlap in situations where quantum mechanical effects cannot be ignored. In order to deal with this overlap of theoretical domains, there has been a tendency to apply the rules of quantum field theory

Casimir effect of rough plates under a magnetic field in Hořava-Lifshitz theory

open access: yesNuclear Physics B
We investigate the Casimir effect for parallel plates within the framework of Hořava-Lifshitz theory in 3+1 dimensions, considering the effects of roughness, anisotropic scaling factor, and an uniform constant magnetic field.

String Theory – Nomological Unification and the Epicycles of the Quantum Field Theory Paradigm [PDF]

open access: yes, 2011
String Theory is the result of the conjunction of three conceptually independent elements: (i) the metaphysical idea of a nomological unity of the forces, (ii) the model-theoretical paradigm of Quantum Field Theory, and (iii) the conflict resulting from ...

Bulk and boundary scattering in the q-state potts mode [PDF]

open access: yes, 1998
This thesis is concerned with the properties of 1 + 1 dimensional massive field theories in both infinite and semi-infinite geometries. Chapters 1, 2 and 3 develop the necessary theoretical framework and review existing work by Chim and Zamolodchikov [1]

Quantum Gravity: Motivations and Alternatives [PDF]

open access: yes, 2009
The mutual conceptual incompatibility between General Relativity and Quantum Mechanics / Quantum Field Theory is generally seen as the most essential motivation for the development of a theory of Quantum Gravity.
