Abstract: We propose a chip-scale hollow-core waveguide using high-contrast gratings as reflectors for dielectric laser acceleration. We show that confinement of a specified accelerating mode can be achieved by adjusting the thickness of a matching layer… read more here.

DOI: 10.1103/physrevaccelbeams.23.054402
Abstract: Due to the tiny apertures of dielectric laser acceleration grating structures within the range of the optical wavelength, wakefields limit the bunch charge for relativistic electrons to a few femtocoulomb. In this paper, we present… read more here.

Abstract: Accelerating neutral atoms is challenging because such particles are not directly manipulated by electric and magnetic fields as charged particles. In our acceleration scheme, the excited atom requires a sufficiently high gradient acceleration force. The… read more here.
