Three level atom optics via the tunneling interaction — •Kai Eckert¹, Maciej Lewenstein¹, Ramon Corbalán², Gerhard Birkl³, Wolfgang Ertmer³, and Jordi Mompart² — ¹Institut für theoretische Physik, Universität Hannover, Germany — ²Departament de Física, Universitat Autònoma de Barcelona, Spain — ³Institut für Quantenoptik, Universität Hannover, Germany

We propose spatial analogues of the stimulated Raman adiabatic passage (STIRAP), coherent population trapping (CPT), and electromagnetically induced transparency (EIT) techniques as tools to coherently and robustly manipulate external degrees of freedom of trapped neutral atoms. These techniques are realized using the tunneling interaction between three trapped states. We analyze the implementation in arrays of optical microtraps and discuss possible applications.
