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 کاملGreen ’ s function theory for one - way particle chains
Recently, it has been shown that a new class of particle chains that support the simultaneous interplay of two-type rotations—geometric and electromagnetic—may possess strong nonreciprocity and one-way guiding effects. Here, we use the Z transform to develop a rigorous Green’s function theory for these one-way chains. A study of the chain’s spectra and its analytic properties in the complex spe...
متن کاملRemarks on Estimates for the Green Function
Uni6n M a t d t i c a Argentina Vol. 35 1990. Introduction The main purpose of this paper is to give a comprehensive motivation, with most of the key ideas used in the recent work by Garroni and Menaldi [lo], on the construction of the Green function G(z, t, (, r) for an integro-differential initial boundary value problem, when the differential operator is a second-order parabolic operator not ...
متن کاملcompactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
15 صفحه اولParticle-particle, particle-scaling function algorithm for electrostatic problems in free boundary conditions.
An algorithm for fast calculation of the Coulombic forces and energies of point particles with free boundary conditions is proposed. Its calculation time scales as N log N for N particles. This novel method has lower crossover point with the full O(N(2)) direct summation than the fast multipole method. The forces obtained by our algorithm are analytical derivatives of the energy which guarantee...
