Tunneling and Coherence in Few and Many Body Systems

This talk will be an overview of situations, such as  high resolution resonance spectroscopy, where the perspective of tunneling in many degrees of freedom (especially dynamical tunneling) is very useful.  The asymptotic nature of many body wave functions in the tunneling regime is interesting and  some results are known and will be discussed. Coherent and incoherent tunneling regimes will also be mentioned.
