Electrostatic Trap and Microtrap Arrays for Cold Polar Molecules on a Chip Surface

doi:10.19596/j.cnki.1001-246x.7880

Abstract

Abstract: An electrostatic surface trap for cold polar molecules with three charged poles is proposed. Distance between trap center and chip surface can be manipulated conveniently by altering voltages applied to the poles. Dynamic process of loading and trapping is simulated with classic method of Monte Carlo. It indicates that a loading efficiency of 40% for ND₃ molecular beam with middle velocity of 11 m·s^-1 is reached. Corresponding temperature of trapped molecules is about 25 mK. Our scheme can be further miniaturized and integrated to form one-dimensional and two-dimensional microtrap arrays which can be used in quantum computing and low-dimensional physics research.

Key words: cold polar molecules, electrostatic surface trap, microtrap array, Monte Carlo simulation
