Models of Quantum Theory, Quantum Field Theory and Spacetime Dynamics |
My work on models began with the attempt to develop a comprehensive computer model of quantum theory (QT)
that enables the simulation of the major QT (Gedanken-) experiments. Soon I had to realize that the feasibility
of such a QT computer model is impeded, not (as expected) by the strange and mysterious nature of QT,
but by the many vague and ambiguous formulations of the theory.
The problems encountered (described in [1] , [2] ,
[14] and [15] )
lead to the conclusion that the apparent deficiencies of QT could (only?) be removed by the provision of a causal
model of QT (including quantum field theory (QFT)) and that the feasibility of constructing a causal model may be a
criteria for the completeness of a physical theory in general.
The development of a causal model of QT/QFT , started with a proposal for a clear (i.e., formal) definition of a “causal model” (see [16], [17]) and continued with the development of (1) a “functional” model of the QT measurement process (see [5] and [6] ) and (2) a computer model of QFT (see [7] ). The work has been accompanied by a number of publications (see [3], [4], [8], [9], [10], [11], [12], [13],[19] and [20]) and included a number of refinement steps. As the (so far) latest refinement step, I found that my causal model of QT/QFT needs a foundation in terms of a causal model of spacetime dynamics. As a repeated surprise, I detected that a causal model of spacetime dynamics, too cannot directly be derived from the standard theory of spacetime, i.e., from general relativity. Refinements and interpretations had to be added to come up with a suitable causal model of spacetime dynamics (see [18], [21], [22]). In the model, space consists of a set of space points, where each space point is connected with a (small) number of neighboring space points via "connections". The processes of the spacetime dynamics (e.g. emergence of space and propagation of space changes) result in a distribution and density of the interconnected space points that represents a curved discrete spacetime in accordance with general relativity. The combined model of spacetime dynamics and QT/QFT enables new solutions for yet controversial subjects in QT/QFT and in cosmology. Further work, including computer simulations, are required to further pursue and refine the major areas of possible new solutions:
