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.

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.
