“…In analogy to light optics one finds the complex index of refraction, n 1 1 ͑2p͞k lab k c ͒Nf͑k c , 0͒. The refractive index of matter for de Broglie waves has been demonstrated in electron holography [7] and extensively studied in neutron optics [8], especially using neutron interferometers [9]. In neutron optics, scattering is dominantly s wave and measuring the refractive index gives information about the scattering length.…”

By inserting a gas cell in one arm of an atom interferometer, we have measured both the attenuation and the phase shift of a sodium matter wave that passes through monatomic (He, Ne, Ar, Kr, and Xe) or molecular gases (N 2 , CO 2 , NH 3 , and H 2 O). This determines the complex index of refraction for Na matter waves and, more accurately, the ratio of the real to the imaginary part of the forward scattering amplitude. These measurements are compared with several semiclassical scattering models.

“…[26,27] as a tool to measure the coherence properties of nuclear states. Second-order correlation functions for fermions were indeed observed in nuclear physics experiments by studying neutron correlations in the decay of highly-excited 44 Ca nuclei [28]. Higher-order correlation functions in pions emitted in heavy-ion collisions were widely used to investigate the state of this form of matter [29,30].…”

Optics and interferometry with matter waves is the art of coherently manipulating the translational motion of particles like neutrons, atoms and molecules. Coherent atom optics is an extension of techniques that were developed for manipulating internal quantum states. Applying these ideas to translational motion required the development of techniques to localize atoms and transfer population coherently between distant localities. In this view position and momentum are (continuouse) quantum mechanical degree of freedom analogous to discrete internal quantum states. In our contribution we start with an introduction into matter-wave optics in section 1, discuss coherent atom optics and atom interferometry techniques for molecular beams in section 2 and for trapped atoms in section 3. In section 4 we then describe tools and experiments that allow us to probe the evolution of quantum states of many-body systems by atom interference.
