Andersson, E. and Calarco, T. and Folman, R. and Andersson, M. and Hessmo, B. and Schmiedmayer, J. (2002) Multimode interferometer for guided matter waves. Physical Review Letters, 88 (10). 100401/1-100401/4. ISSN 0031-9007
Atoms can be trapped and guided with electromagnetic fields, using nanofabricated structures. We describe the fundamental features of an interferometer for guided matter waves, built of two combined Y-shaped beam splitters. We find that such a device is expected to exhibit high contrast fringes even in a multimode regime, analogous to a white light interferometer.
