Abstract
A new combined evanescent light–electrostatic atom trap is proposed. Cold atoms repulse from the evanescent wave of the blue-detuned (quasi) resonant laser light formed in the total internal reflection conditions and electrostatically attract to the sharp conducting tip located close to the glass–vacuum interface. It is shown that a few milliKelvin deep and subwavelength-size traps can be formed with such an approach. These traps can be easily “scaled” by using an array of tips, which makes them a perspective object for applications in quantum computing.
