Source Galerkin Calculations in Scalar Field Theory
In this paper, we extend previous work on scalar φ theory using the Source Galerkin method. This approach is based on finding solutions Z[J ] to the lattice functional equations for field theories in the presence of an external source J . Using polynomial expansions for the generating functional Z, we calculate propagators and mass-gaps for a number of systems. These calculations are straightfo...
متن کاملMinimal coupling method and the dissipative scalar field theory
Quantum field theory of a damped vibrating string as the simplest dissipative scalar field investigated by its coupling with an infinit number of Klein-Gordon fields as the environment by introducing a minimal coupling method. Heisenberg equation containing a dissipative term proportional to velocity obtained for a special choice of coupling function and quantum dynamics for such a dissipative ...
متن کاملScalar Field Theory in the Derivative Expansion
The quantum correlations of scalar fields are examined as a power series in derivatives. Recursive algebraic equations are derived and determine the amplitudes; all loop integrations are performed. This recursion contains the same information as the usual loop expansion. The approach is pragmatic and generalizable to most quantum field theories.
متن کاملDifferential Renormalization of Scalar Field Theory in the Background-Field Method
We introduce an approach for calculating the quantum loop corrections in the φ theory. Differential regularization and background-field method are essential tools and are used to calculate the effective action of the theory to two-loop order. Our approach is considerably simpler than other known methods and can be readily extended to higher-loop calculations and to other models.
متن کاملThe generalized Fényes–Nelson model for free scalar field theory
The generalized Fényes–Nelson model of quantum mechanics is applied to the free scalar field. The resulting Markov field is equivalent to the Euclidean Markov field with the times scaled by a common factor which depends on the diffusion parameter. This result is consistent between Guerra’s earlier work on stochastic quantization of scalar fields. It suggests a deep connection between Euclidean ...
