The semiclassical propagator in field theory
We consider scalar field theory in a changing background field. As an example we study the simple case of a spatially varying mass for which we construct the semiclassical approximation to the propagator. The semiclassical dispersion relation is obtained by consideration of spectral integrals and agrees with the WKB result. Further we find that, as a consequence of localization, the semiclassic...
متن کاملAny Particle Binding Energy Calculations Using Propagator Theory
Although accurate correlated calculations have reached an advanced state in terms of theory and computational implementation, interpretation of these results in terms of the orbital concepts based on an one particle picture is still a difficult issue. In the case of electronic structure calculations, propagator theory (PT) has been successfully used to overcome this problem, since this theory o...
متن کاملThe Landau gauge lattice ghost propagator in stochastic perturbation theory
We present oneand two-loop results for the ghost propagator in Landau gauge calculated in Numerical Stochastic Perturbation Theory (NSPT). The one-loop results are compared with available standard Lattice Perturbation Theory in the infinite-volume limit. We discuss in detail how to perform the different necessary limits in the NSPT approach and discuss a recipe to treat logarithmic terms by int...
متن کاملBulk-Boundary Propagator in Liouville Theory on a Disc
We study Liouville theory on worldsheets with boundary using the solutions of KnizhnikZamolodchikov equation involving a degenerate representation of the Virasoro algebra. The expression for bulk-boundary propagator on a disc is proposed.
متن کاملStudy of the influence of propagator amplitude correction on image amplitude using beamlet propagator with local WKBJ approximation
Localized WKBJ correction based on Local Cosine Basis (LCB) beamlet propagator is applied in postand pre-stack migration to study its influence on image amplitude. 2D SEG/EAGE salt model is used for demonstration. The results indicate that localized WKBJ correction have some improvement on the image amplitude though not very dramatic for 2D SEG/EAGE salt data with relatively smalloffset acquisi...
