Getting Dressed for Quantum Technology


Professor Barry M Garraway

Department of Physics and Astronomy, University of Sussex, UK


Dressing atoms with radio-frequency and microwave radiation opens up  new possibilities for atom trap and waveguide designs [1]. This is because of the flexibility inherent in the vector coupling of a magnetic dipole moment to electromagnetic fields which can be varied in time, frequency, orientation and space. This may in turn result in quantum technology applications to sensing, metrology, interferometry and atomtronics.

This talk will introduce the concept of the dressed atom, and present both old and new designs of matter-wave ring traps and race tracks [2] with the potential to make new atomic gyroscopes. Work will also be presented on radio-frequency dressed lattices: these do not involve optical beams and are based on arrays of current carrying wires [3]. They are highly flexible and can be used to form a regular lattice, dipolar lattice, or ladder lattice.
