Quantization and eigenvalue distribution of noncommutative scalar field theory
The quantization of noncommutative scalar field theory is studied from the matrix model point of view, exhibiting the significance of the eigenvalue distribution. This provides a new framework to study renormalization, and predicts a phase transition in the noncommutative φ model. In 4-dimensions, the corresponding critical line is found to terminate at a non-trivial point.
متن کاملManifestly covariant canonical quantization I: the free scalar field
Classical physics is reformulated as a constrained Hamiltonian system in the history phase space. Dynamics, i.e. the Euler-Lagrange equations, play the role of first-class constraints. This allows us to apply standard methods from the theory of constrained Hamiltonian systems, e.g. Dirac brackets and cohomological methods. In analogy with BRST quantization, we quantize in the history phase spac...
متن کاملQuantization of the scalar field in a static quantum metric
We investigate Hamiltonian formulation of quantum scalar fields in a static quantum metric. We derive a functional integral formula for the propagator. We show that the quantum metric substantially changes the behaviour of the scalar propagator and the effective Yukawa potential.
متن کاملPath integral quantization of parametrised field theory
Free scalar field theory on a flat spacetime can be cast into a generally covariant form known as parametrised field theory in which the action is a functional of the scalar field as well as the embedding variables which describe arbitrary , in general curved, foliations of the flat spacetime. We construct the path integral quantization of parametrised field theory in order to analyse issues at...
متن کاملOn Field Theory Quantization around Instantons
With the perspective of looking for experimentally detectable physical applications of the socalled topological embedding, a procedure recently proposed by the author for quantizing a field theory around a non-discrete space of classical minima (instantons, for example), the physical implications are discussed in a “theoretical” framework, the ideas are collected in a simple logical scheme and ...
