Particle Interpretations and Green Functions for a Free Scalar Field∗
The formalism of Ashtekar and Magnon [2] for the definition of particles in quantum field theory in curved spacetime is further developed. The relation between basic objects of this formalism (e.g., the complex structure) and different Green functions is found. It allows one to derive composition laws for Green functions. The relation of two definitions of particles is reformulated in the forma...
متن کاملScalar Field Theory on a Causal Set in Histories Form
We recast into histories-based form a quantum field theory defined earlier in operator language for a free scalar field on a background causal set. The resulting decoherence functional resembles that of the continuum theory but the counterpart of the d’Alembertian operator is nonlocal and a generalized inverse of the discrete retarded Green function. We comment on the significance of this and w...
متن کاملSum-over-histories representation for the causal Green function of free scalar field theory.
A set of Green functions Gα(x − y), α ∈ [0, 2π[, for free scalar field theory is introduced, varying between the Hadamard Green function ∆1(x − y) ≡ 〈0 | {φ(x), φ(y)} | 0〉 and the causal Green function Gπ(x − y) = i∆(x − y) ≡ [φ(x), φ(y)]. For every α ∈ [0, 2π[ a path-integral representation for Gα is obtained both in the configuration space and in the phase space of the classical relativistic ...
متن کاملNew Method for Exact Calculation of Green Functions in Scalar Field Theory
We present a new method for calculating the Green functions for a lattice scalar field theory in D dimensions with arbitrary potential V (φ). The method for non-perturbative evaluation of Green functions for D=1 is generalized to higher dimensions. We define “hole functions” A (i = 0, 1, 2, · · · , N−1) from which one can construct N -point Green functions. We derive characteristic equations of...
متن کاملRelation between worldline Green functions for scalar two-loop diagrams
We discuss a relation between two-loop bosonic worldline Green functions which are obtained by Schmidt and Schubert in two different parametrizations of a twoloop worldline. These Green functions are transformed into each other by some transformation rules based on reparametrizations of the proper time and worldline modular parameters. 1 Fellow of the Danish Research Academy, [email protected]...
