Funding:

This is a collaborative project with the Cold Matter group at Imperial College London, funded by the EPSRC grant entitled "MMQA: Microkelvin Molecules in a Quantum Array" EP/I012044/1. (December 2010 - December 2015)

Details of this collaboration can be found on the MMQA website.

We also acknowledge support from the Royal Society through the International Exchanges Scheme.

Outline:
Ultracold dipolar molecules are an interesting area of atomic and molecular physics, with the possible future applications including:
  • The use of dipolar ground state molecules in optical lattice potentials for quantum computation.
  • The study of degenerate quantum gases of molecules.
  • However, there are many fascinating experiments to do along the way as well, including:
  • The use of Feshbach resonances both to control the interactions within a quantum degenerate gas and as a means to produce ultracold molecules.
  • The study of a mixture of two different quantum gases, possibly including a mix of fermions and bosons.

  • Objectives:
    The specific objectives of the project include:
  • Cooling both ytterbium and caesium using a dual species Zeeman slower and capturing them in separate magneto-optical traps.
  • Combining them in an optical trap and cooling both to degeneracy.
  • The location and identification of interspecies Feshbach resonances.
  • The creation of heteronuclear molecules of CsYb and the subsequent transfer of these highly excited molecules to the ground state.
