QMeCha: quantum Monte Carlo package for fermions in embedding environments
Matteo Barborini, Jorge Charry, Matej Ditte +3
We present the first open access version of the QMeCha (Quantum MeCha) code, a quantum Monte Carlo (QMC) package developed to study many-body interactions between different types o…
Molecules in Environments: Towards Systematic Quantum Embedding of Electrons and Drude Oscillators
Matej Ditte, Matteo Barborini, Leonardo Medrano Sandonas +1
We develop a quantum embedding method that enables accurate and efficient treatment of interactions between molecules and an environment, while explicitly including many-body corre…
The three-center two-positron bond
Jorge Charry, Félix Moncada, Matteo Barborini +4
Computational studies have shown that one or more positrons can stabilize two repelling atomic anions through the formation of two-center positronic bonds. In the present work, we…
