Final Report - QUANTUM MODELLING (New computational tools for the modelling of correlations in quantum systems)

Project ID: 220335
Funded under: FP7-PEOPLE


The quantum world exhibits phenomena that sometimes appear counterintuitive. Superconductivity is a well known example. To understand the quantum world, we have to resort to mathematical models that lead to complicated mathematical equations.

Often approximate solutions to these equations are sufficient to describe quantum phenomena, as is seen for example in the Bardeen-Cooper-Schrieffer (BCS) mean field theory of superconductivity. If one wants to study more complicated quantum correlations, one has to rely on methods that go beyond the mean field.

The aim of the QUANTUM MODELLING project was to use insights from exactly solvable models in order to improve the accuracy of quantum Monte Carlo methods for the modelling of correlated quantum systems such as ultracold atomic gases, nuclear matter and non-conventional superconductors.

The report highlights that one of the important breakthroughs of the QUANTUM MODELLING project was the development of a computer code that can solve the RG equations efficiently even for thousands of particles. This opened the way to extend the use of RG models as a fundamental tool to analyse correlations in quantum systems.
