Physical Review A 79(051402).1050-2947http://nrs.harvard.edu/urn-3:HUL.InstRepos:10591635We implemented a multipulse interferometer scheme that allows us to study a quantum kicked rotor by observing dephasing of momentum coherence. Our study shows that momentum coherence can be nearly perfectly preserved under conditions where the mean energy as a function of the kick number is known to increase without bound. The accompanying width narrowing of these coherences may provide a new method for accurate measurement of the recoil frequency.en-USJournal Article2013-04-2910.1103/PhysRevA.79.051402
