Nonequilibrium Green's functions (NEGF) have emerged as a pivotal theoretical framework for investigating the time-dependent behaviour of quantum many-body systems.

A method is outlined for the determination of the Green's function associated with any partial differential equation for arbitrary domains. The Green's function is obtained as the solution of an ...

This paper introduces a new windowed Green function (WGF) method for the numerical integral-equation solution of problems of electromagnetic scattering by obstacles in the presence of dielectric or ...
