Piezoelectrically actuated time-averaged atomic microtraps.

West, A. D. and Wade, C. G. and Weatherill, K. J. and Hughes, I. G. (2012) 'Piezoelectrically actuated time-averaged atomic microtraps.', Applied physics letters., 101 (2). 023115.


We present a scheme for creating tight and adiabatic time-averaged atom-traps through the piezoelectric actuation of nanomagnetic structures. We show that potentials formed by the circular translation of magnetic structures have several advantages over conventional rotating-field techniques, particularly for high trap frequencies. As the magnitude of the actuation is changed, the trapping potential can be changed adiabatically between harmonic 3D confinement and a toroidal trap.
