Efficient implementation of the nonequilibrium Green function method for electronic transport calculations [PDF]

, 2009
An efficient implementation of the nonequilibrium Green function method combined with the densityfunctional theory, using localized pseudoatomic orbitals, is presented for electronic transport calculations of a system connected with two leads under a ...

Influence of an L^{p}-perturbation on Hardy-Sobolev inequality with singularity a curve [PDF]

Opuscula Mathematica, 2021
We consider a bounded domain \(\Omega\) of \(\mathbb{R}^N\), \(N \geq 3\), \(h\) and \(b\) continuous functions on \(\Omega\). Let \(\Gamma\) be a closed curve contained in \(\Omega\).

From a local Green function to molecular charge transport [PDF]

, 2003
A local-orbital based ab initio approach to obtain the Green function for large heterogeneous systems is developed. First a Green function formalism is introduced based on exact diagonalization.

New Hermite Hadamard type inequalities for twice differentiable convex mappings via Green function and applications

Moroccan Journal of Pure and Applied Analysis, 2016
We derive some Hermite Hamamard type integral inequalities for functions whose second derivatives absolute value are convex. Some eror estimates for the trapezoidal formula are obtained. Finally, some natural applications to special means of real numbers

Evaluation of the One-Dimensional L^p Sobolev Type Inequality

Mathematics, 2020
This study applies the extended L 2 Sobolev type inequality to the L p Sobolev type inequality using Hölder’s inequality. The sharp constant and best function of the L p Sobolev type inequality are found using a Green ...

Dominance of forest structural traits in shaping soil bacterial community assembly in Beijing’s urban forests

Frontiers in Soil Science
Urban forests constitute vital ecological interfaces between built environments and natural systems, yet the mechanisms driving soil microbial community assembly in these ecosystems remain poorly understood.
