Demonstration of the temporal matter-wave Talbot effect for trapped matter waves
Published 2 May 2011 in quant-ph and physics.atom-ph | (1105.0295v1)
Abstract: We demonstrate the temporal Talbot effect for trapped matter waves using ultracold atoms in an optical lattice. We investigate the phase evolution of an array of essentially non-interacting matter waves and observe matter-wave collapse and revival in the form of a Talbot interference pattern. By using long expansion times, we image momentum space with sub-recoil resolution, allowing us to observe fractional Talbot fringes up to 10th order.
