Green’s function for the semi-infinite strip in terms of an improper integral [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2020
In this paper Green’s function for the semi-infinite strip (which is the two-dimensional Green’s function for a groove of infinite depth and length) is determined in the form of an improper integral, as opposed to the standard summation form ...

On a nabla fractional boundary value problem with general boundary conditions

open access: yesAIMS Mathematics, 2020
In this article, we consider a nabla fractional boundary value problem with general boundary conditions. Brackins & Peterson [5] gave an explicit expression for the corresponding Green’s function.

Numerically Stable form of Green’s Function for a Free-Free Uniform Timoshenko Beam

open access: yesMathematics, 2022
Beam models are widely applied in civil engineering, transport, and industry because the beams are basic structural elements. When dealing with the high-order modes of beam in the context of applying the modal analysis method, the numerical instability ...

Constant-Sign Green’s Function of a Second-Order Perturbed Periodic Problem

open access: yesAxioms, 2022
In this paper, we were interested in obtaining the exact expression and studying the regions of constant sign of Green’s function related to a second-order perturbed periodic problem coupled with integral boundary conditions at the extremes of the ...

Computation of Green's function by local variational quantum compilation

open access: yesPhysical Review Research, 2023
Computation of the Green's function is crucial to study the properties of quantum many-body systems such as strongly correlated systems. Although the high-precision calculation of the Green's function is a notoriously challenging task on classical ...

Calculating the Green’s function of two-site fermionic Hubbard model in a photonic system

open access: yesNew Journal of Physics, 2022
The Green’s function has been an indispensable tool to study many-body systems that remain one of the biggest challenges in modern quantum physics for decades. The complicated calculation of the Green’s function impedes the research of many-body systems.

First-principles Green's-function method for surface calculations: A pseudopotential localized basis set approach [PDF]

open access: yes, 2017
We present an efficient implementation of a surface Green's-function method for atomistic modeling of surfaces within the framework of density functional theory using a pseudopotential localized basis set approach. In this method, the system is described
