Potential focus areas

  1. Basic atomic/molecular physics, including potentials, Feshbach experiments and theoretical modeling, ab initio calculations, molecular structure, STIRAP parameters and optimization, molecular properties
  2. Chemistry and field control with ultracold polar molecules, including elastic and inelastic collisions, reactions, vibrational relaxation, collision complexes and their resonances, pendular states and manipulating dipoles, control of molecular quantum states, lattice and reduced dimension effects on chemistry and control. We also are considering molecular ions.
  3. Few body phenomena, such as Efimov physics and non-Efimov 3-body or higher, for atoms or for molecular dipoles, universal and non-universal behavior, including the surprising universality of the 3-body parameter.
  4. Condensed matter issues, including phases of dipolar matter, many-body phenomena, rotational excitons, correlated spins, and any of these in the static or dynamic (time-dependent, non equilibrium) sense, and including the quite significant area of manipulating atom mixtures in lattices to make preformed pairs to associate to molecules.
  5. Quantum information, quantum computing, I put these in a separate category, since it could involve several of the above integrated together and the field has its own "logic", or way of viewing things.
  6. Theoretical methods--do new methods need to be developed in any of these areas (the answer is yes), and where do we just need to apply existing theory.
  7. Experiments--hearing from our visitors, but also where can theory either help existing experiments or propose really new ones that appear feasible from what we know now.
  8. Experiments with atomic dipoles (Eb, Dy) are relevant to a number of our topics, including the transition from atomic-like to universal dipolar collisions.
  9. Precision measurements: molecular spectroscopy, fundamental issues (P,T-violation, time-dependence of constants), molecular clocks, ...

Personal goals

Jordi Mur-Petit: I'd like to learn/hear/get up-to-date with issues like:
  • Many-body physics: calculation methods both for static and dynamics problems (QMC, DMRG, DMFT, MCTDH, etc.)
  • Fundamental issues (parity- and time-violation, time-dependence of constants): state-of-the-art, experimental prospects and challenges, theoretical input needed.
  • Quantum simulation: getting a realistic proposal of a set-up, taking into account experimental requirements such as how to trap and cool molecules, how to align them (to get a (pseudo)spin well-defined), how to control them with external fields.
