The Forgotten History of Wave Function Variance Optimization and its Relevance for Neural-Network VMC

Dario Bressanini

We revisit the almost century-old question of which functional of the local energy best optimizes a trial wave function, a problem of central importance in Variational Monte Carlo…

The two-positron gluic bond as a manifestation of "super" van der Waals interactions

Mohammad Goli, Dario Bressanini, Shant Shahbazian

Recently, it has been demonstrated theoretically that the interaction of two PsH atoms, each being a stable bound state of a hydrogen atom and a positronium atom, is attractive, le…

On the nature of the two-positron bond: Evidence for a novel bond type

Mohammad Goli, Dario Bressanini, Shant Shahbazian

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 d…

Manifestation of Universality in the Asymmetric Helium Trimer and in the Halo Nucleus C

Dmitry K. Gridnev, Dario Bressanini

We prove that the corner angle distributions in the bound three-body system AAB, which consists of two particles of type A and one particle of type B, approach universal form if th…

Nodal surfaces and interdimensional degeneracies

Pierre-François Loos, Dario Bressanini

The aim of this paper is to shed light on the topology and properties of the nodes (i.e. the zeros of the wave function) in electronic systems. Using the "electrons on a sphere" mo…

Delayed Rejection Variational Monte Carlo

Dario Bressanini, Gabriele Morosi, Silvia Tarasco +1

A new acceleration algorithm to address the problem of multiple time scales in variational Monte Carlo simulations is presented. After a first attempted move has been rejected, the…
