Response to `Local and global definitions of time:Cosmology and quantum theory'
Local global definitions time Cosmology quantum theory
2016/6/15
I will discuss the notion of time and spatial finiteness from the perspective of observational cosmology. Our observed universe is well described at early times by small fluctuations in the spatial gr...
Time and Quantum Theory:A History and A Prospectus
time quantum Pauli's theorem events Dirac Heisenberg
2016/6/15
In this paper I am concerned with analyzing in detail how ideas and expectations regarding the role of time in quantum theory arose and evolved in the early years of quantum mechanics (from 1925-27). ...
Local and global definitions of time:Cosmology and quantum theory
Cosmology relational time spatial extent time
2016/6/15
I will give a broad overview of what has become the standard paradigm in cosmology. I will describe the relational (\`{a} la Leibnitz) notion of time that is often used in cosmological calculations an...
I offer an account of how the quantum theory we have helps us explain the enormous variety of phenomena it is generally taken to explain. The account depends on what I have elsewhere called a pragmati...
Topos-Theoretic Approaches to Quantum Theory
Topos theory quantum logic category theory operational quantum mechanics
2016/5/31
Starting from a naive investigation into the nature of experiments on a physical system one can argue that states of the system should pair non-degenerately with physical observables. This duality is ...
Recent years have seen a good deal of work done on one of the most mind blowing and conceptually radical views in quantum mechanics, namely the ‘many worlds’ interpretation of quantum mechanics. Many ...
(Never) Mind your p's and q's:Von Neumann versus Jordan on the Foundations of Quantum Theory
Pascual Jordan John von Neumann transformation theory probability amplitudes canonical transformations Hilbert space spectral theorem
2016/5/30
In early 1927, Pascual Jordan (1927b) published his version of what came to be known as the Dirac-Jordan statistical transformation theory. Later that year and partly in response to Jordan, John von N...

The Quantum Theory of General Relativity at Low Energies
Quantum field theory low energy quantum the interaction energy general relativity low energy
2014/12/23
In quantum field theory there is now a well developed technique, effective field theory, which allows one to obtain low energy quantum predictions in “non-renormalizable” theories, using only the degr...
A Critical Discussion About The Methodology Of Quantum Theory
Realism Individuation Locality Determinism Correlated Quantum Systems Entanglement Swapping Operative Methodology
2011/8/17
Abstract: It is argued that the traditional "realist" methodology of physics, according to which human concepts, laws and theories can grasp the essence of reality, is incompatible with the most fruit...
de Broglie waves as the "Bridge of Becoming" between quantum theory and relativity
de Broglie waves quantum theory and relativity quantum level
2011/8/16
Abstract: It is hypothesized that de Broglie's 'matter waves' provide a dynamical basis for Minkowski spacetime in an antisubstantivalist or relational account. The relativity of simultaneity is seen ...
The holistic structure of causal quantum theory, its implementation in the Einstein-Jordan conundrum and its violation in more recent particle theories
causal quantum theory holistic structure Einstein-Jordan conundrum High Energy Physics - Theory
2011/8/26
Abstract: Recent insights into the conceptual structure of localization in QFT ("modular localization") led to clarifications of old unsolved problems. One is the Einstein-Jordan conundrum which led J...
Review of the Topos Approach to Quantum Theory
the Topos Approach Quantum Theory Quantum Physics
2011/7/27
Abstract: Topos theory has been suggested by D\"oring and Isham as an alternative mathematical structure with which to formulate physical theories. In particular, the topos approach suggests a radical...

High-order harmonic generation (HHG) by hydrogenlike atoms/ions in the uniform periodic electric field, formed by the two linearly polarized counterpropagating laser beams of relativistic intensities,...
Noncommutative field theories are a class of theories beyond the standard model of elementary particle physics. Their importance may be summarized in two facts.Firstly as field theories on noncommutat...
