Atom-light interactions in quasi-one-dimensional nanostructures: A Green's-function perspective [PDF]
, 2016 Based on a formalism that describes atom-light interactions in terms of the classical electromagnetic Green's function, we study the optical response of atoms and other quantum emitters coupled to one-dimensional photonic structures, such as cavities ...

Asymptotic extraction approach for antennas in a multilayered spherical media [PDF]
, 2010 An efficient algorithm is introduced to enhance the convergence of dyadic Green's functions (DGF) in a layered spherical media where asymptotic expressions have been developed. The formulated expressions involve an infinite series of spherical eigenmodes

Green's functions and existence of solutions of nonlinear fractional implicit difference equations with Dirichlet boundary conditions [PDF]
Opuscula MathematicaThis article is devoted to deduce the expression of the Green's function related to a general constant coefficients fractional difference equation coupled to Dirichlet conditions. In this case, due to the points where some of the fractional operators are

Landau quantized dynamics and spectra for group-VI dichalcogenides, including a model quantum wire
AIP Advances, 2017 This work is concerned with the derivation of the Green’s function for Landau-quantized carriers in the Group-VI dichalcogenides. In the spatially homogeneous case, the Green’s function is separated into a Peierls phase factor and a translationally ...

Analyticity and crossing symmetry of superstring loop amplitudes
Journal of High Energy Physics, 2019 Bros, Epstein and Glaser proved crossing symmetry of the S-matrix of a theory without massless fields by using certain analyticity properties of the off-shell momentum space Green’s function in the complex momentum plane.

Self-consistent second-order Green's function perturbation theory for periodic systems. [PDF]
Journal of Chemical Physics, 2015 Despite recent advances, systematic quantitative treatment of the electron correlation problem in extended systems remains a formidable task. Systematically improvable Green's function methods capable of quantitatively describing weak and at least ...

Confined coherence and analytic properties of Green's functions
, 1997 A simple model of noninteracting electrons with a separable one-body potential is used to discuss the possible pole structure of single particle Green's functions for fermions on unphysical sheets in the complex frequency plane as a function of the ...

An estimate for the Green’s function [PDF]
Proceedings of the American Mathematical Society, 2014 Let K K be a continuum on C {\mathbb {C}} and let g Ω ( K ) ( z , ∞ ) g_{\Omega (K)}(z,\infty ) be the Green’s function of Ω ( K
