Guided atom optics: recent progress and applications
In this talk, I will describe some recent advances in the field of guided atom
optics. In the first part, I will explain the experimental techniques that
allow for the realization of a transversally monomode guided atom laser. These
systems are the equivalent for matter waves of monomode fibers in optics. In
the second part of the talk, I will comment on a few experiments performed
with such a tool in order to investigate complex potentials. We have recently
realized a distributed Bragg reflector for matter waves where the succession
of layers is provided by a light pattern resulting from the interference of
two laser beams that provides a series of light walls sepatated by a few
hundreds of nm. By modulating the light wall intensities, if is even possible
to engineer the momentum distribution of the matter wave and to realize, for
instance, ultra selective velocity filters. In the last part of the talk, I
will describe other recent experiments where the transverse of degrees of
freedom in ths guide play an important role. We will give an example with the
interaction of an off-center defect that can trigger a transition to chaos in
this system. Another example will be discussed on the very first experiments
dealing with the realization of a guided matter wave beam splitter.
