摘　　要：We propose a scheme for a chip-based dynamic micro atom trap where the trap potentials are created by square wave radiation and an inhomogeneoas static magnetic field. The parameters of this kind of trap array can be modulated dynamically. Both one-dimensional （I-D） and two-dimensional （2-D） trap array potentials for 6Li atoms are discussed. The 1-D trap is combined by a square wave radiation （6 kHz） and a gradient magnetic field （300G/cm）, the array constant of 1-D trap is 0.85 μm. Since the trap array does not require any laser field, it can be easily integrated on a chip and it is useful in applications of scalable quantum information processing.We propose a scheme for a chip-based dynamic micro atom trap where the trap potentials are created by square wave radiation and an inhomogeneoas static magnetic field.
