Theory of Quantum Systems at Surfaces



The theory team at QNS will be set up to work closely with the experimental groups to understand, model, and predict the quantum properties of the studied systems.

One part of the team will focus on first-principle modeling. As part of this effort, QNS will install a medium-sized high-performance computer cluster to host these compute intensive calculations. A second part will focus on understanding the interaction of the quantum systems with the local environment. These interactions often give rise to so-called decoherence: the irrecoverable loss of quantum information to the environment.

An important element of the theory team will be a very active exchange of people with the global theory community. We are envisioning the QNS theory team to be host to many domestic and foreign theory experts, who will stay for extended periods to interact with the whole of QNS.


Long-Term Goals

  • Develop methods to predict the quantum states and dynamic properties of atoms on surfaces
  • Develop theoretical understanding of quantum coherence, with emphasis on mitigating decoherence
  • Investigate the transition from quantum to classical behavior, including the quantum measurement problem

Near-Term Goals

  • Work in close collaboration with the experimental teams to understand the measurements
  • Make predictions for better systems to study
  • Install a high-performance computing cluster at QNS
  • Develop a network of international theory collaborators, set up a theory hub for QNS
