Piezoelectrically actuated time-averaged atomic microtraps [PDF]
Applied Physics Letters, 2012 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.
