Quantum optical approach to kinetic energy densities — •Dirk Seidel1, Gerhard C. Hegerfeldt1, and J. Gonzalo Muga21Institut für Theoretische Physik, Universität Göttingen, Friedrich-Hund-Platz 1, 37077 Göttingen — 2Departamento de Quimica-Fisica, Universidad del Pais Vasco, Apartado Postal 644, 48080 Bilbao, Spain

We give a measurement based (operational) approach to a positive quantum version of the local kinetic energy density. This is achieved by considering the detection rate of photons which are emitted by a moving three-level atom excited by a localized laser beam. The relation to quantum arrival-time distributions obtained with the same type of experiment is pointed out.
