Publication in “Quantum Science and Technology”
RSA FG researcher and data scientist Luca Papariello, a graduate of ETH Zurich, is co-author of a paper that makes a new contribution to quantum simulation. The article has just been published in the Open Access journal “Quantum Science and Technology” by IOP Publishing.
In recent years, the field of quantum simulations, both by classical software and quantum software, has experienced significant growth. This is a new field of research, and the focus issue is one of the first compilations of its kind.
Luca Papariello describes the contents of the paper like this:
“The paper we have submitted – which has already been accepted and is already available online – introduces the software Multi-Configurational Time-Dependent Hartree for Indistinguishable Particles (acronym: MCTDH-X), which is hosted at http://ultracold.org and to whose development I am still contributing. We show how it works and what possibilities it offers by analyzing the physics of a system consisting of a few interacting quantum particles (bosons or fermions) trapped in a double-well potential. The study of this minimal model system allows us to provide an easy to understand tutorial and at the same time to contribute an original research article.
The MCTDH-X software is a powerful tool for the study of interacting quantum many-body systems and as such applicable in fields ranging from atomic physics to condensed matter physics. Analytical solutions for quantum many-body systems are very rare and exist only for simple model systems. The tool described in the paper allows the investigation of complex systems that are currently found in state-of-the-art experiments. MCTDH-X will therefore provide a better understanding of the phenomena observed in the laboratories and allow the prediction of new phenomena which then need to be experimentally confirmed.”
