The energetic stability of positron–dianion systems [A−; e+; A−] is studied via many-body
theory, where A− includes H−, F−, Cl−, and the molecular anions (CN)− and (NCO) …

This work presents an extension of the projector operator embedding scheme of Manby et
al.[J. Chem. Theory Comput. 8, 2564 (2012)] in a multicomponent (MC) framework. Here, a …

A major challenge in contemporary electronic structure theory involves the development of
methods to describe in a balanced manner the contribution of correlation effects to energy …

This study explores the energetic stability and physical properties of Ps 2 XY Ps_2XY
complexes formed by two halide anions (X−, Y−= F−, X−, Br−), and two positrons (Ps …

The nature of the newly proposed two-positron bond in (PsH) 2, which is composed of two
protons, four electrons and two positrons, is considered in this contribution. The study is …

Certain atoms, molecules, and clusters can bind an excess electron or positron in a diffuse
orbital. Given the weak binding energy of these states, usually on the order of tens to …

The positron is the antiparticle of the electron, possesing the same mass and obeying the
same spin statistics but with an opposite charge. When a positron and an electron collide …
