Dressing ultra-cold atoms for control and quantum technology
Department of Physics and Astronomy, University of Sussex, Falmer, Brighton, BN1 9QH, United Kingdom
摘要： Dressing atoms with radio-frequency and microwave radiation opens up new possibilities for ultra-cold atoms and a BEC in new types of trap and in new topologies involving waveguides [1,2]. 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 (with ring traps and gyroscopes [3,4]), metrology, interferometry and atomtronics. In this talk we will introduce the concept of the dressed atom, and present several designs for matter-wave ring traps, as well as rf-dressed lattices for ultra-cold atoms [5,6] and a description of Landau-Zener losses from these traps .
