Quantum dynamics in spatially resolved two-atom cavity QED (A. Neuzner)
The
Tavis-Cummings model of N>1 atoms coupled to an optical cavity is a
cornerstone for the description of collective light-matter interaction.
We realize this system by trapping two atoms with an optical lattice in a
microcavity and image the atoms with single-site resolution. We find
saturation and suppression of scattering from a transversal laser as
well as photon-pair generation in the latter case.
Solid State Attosecond
Dynamics (Dr. M. Schultze)
Electric-field-induced charge separation (polarization) is the
most fundamental manifestation of the interaction of light with matter.
Attosecond solid state spectroscopy provides direct time-domain access
to this interaction allowing to test important hypotheses regarding the
underlying physical processes. I will discuss two recent experiments
exploring the temporal evolution of laser induced excitation in the
linear regime in a classic semiconductor and the nonlinear interaction
of transparent dielectrics with ultrashort laser pulses
