We present and benchmark a self-energy approach for quasiparticle energy calculations that goes beyond Hedin's GW approximation by adding the full second-order self-energy (FSOS-W) contribution.

Communications in statistics. Simulation and computation, 2022
We consider two independent populations, N(μ1,σ12) and N(μ2,σ22), with all four parameters assumed unknown, (μ1,μ2)∈R2 and (σ1,σ2)∈R+2. In this paper, our goal is to revisit sequential minimum risk point estimation (MRPE) problems for the parameter μ1−μ2(

Journal of Chemical Theory and Computation
Correlations associated with dynamical fluctuations of electrons in molecules can be spatially localized, which offers the promise of reducing the compute complexity of many-body quantum chemical methods such as second-order Møller-Plesset (MP2) theory ...

The second-order Møller-Plesset perturbation (MP2) theory is a post-Hartree-Fock method widely used to describe weak correlation energies in solids and molecules, but its high computational cost scales as O(N5).

Mechanics based design of structures and machines
This study focuses on a study of free vibration of non-circular composite nanorods using second-order strain gradient theory. Short-fibers are used to strengthen the mechanical behavior of the cross-section. The main objective of this study is to present
