Resumen:
Ion Coulomb crystals are currently establishing themselves as a highly
controllable test bed for mesoscopic systems of statistical mechanics.
The detailed experimental interrogation of the dynamics of these
crystals, however, remains an experimental challenge. In this work, we
show how to extend the concepts of multidimensional nonlinear
spectroscopy to the study of the dynamics of ion Coulomb crystals. The
scheme we present can be realized with state-of-the-art technology and
gives direct access to the dynamics, revealing nonlinear couplings even
in the presence of thermal excitations. We illustrate the advantages of
our proposal showing how two-dimensional spectroscopy can be used to
detect signatures of a structural phase transition of the ion crystal,
as well as resonant energy exchange between modes. Furthermore, we
demonstrate in these examples how different decoherence mechanisms can
be identified.
