Suppression of Bragg scattering by collective interference of spatially ordered atoms with a high-Q cavity mode / Zippilli, Stefano (Universität Ulm. Abteilung für Quantenphysik) ; Morigi, Giovanna (Universität Ulm. Abteilung für Quantenphysik) ; Ritsch, Helmut (Universität Innsbruck. Institut für Theoretische Physik) ; American Physical Society
When N driven atoms emit in phase into a high-Q cavity mode, the intracavity field generated by collective scattering interferes destructively with the pump driving the atoms. Hence atomic fluorescence is suppressed and cavity loss becomes the dominant decay channel for the whole ensemble. [...]

Eigenmodes and thermodynamics of a Coulomb chain in a harmonic potential / Morigi, Giovanna (University of Ulm. Department of Quantum Physics) ; Fishman, Shmuel (Technion. Department of Physics (Haifa, Israel)) ; American Physical Society
The density of ions trapped in a harmonic potential in one dimension is not uniform. Consequently the eigenmodes are not phononlike waves. We calculate the long-wavelength modes in the continuum limit, and evaluate the density of states in the short-wavelength limit for chains of N≫1 ions. [...]

Single-molecule photobleaching probes the exciton wave function in a multichromophoric system / Hernando Campos, Jordi (Institute for Nanotechnology (Enschede, Països Baixos)) ; Hoogenboom, Jacob P. (Institute for Nanotechnology (Enschede, Països Baixos)) ; van Dijk, Erik M. H. P.

(Institute for Nanotechnology (Enschede, Països Baixos))
The exciton wave function of a trichromophoric system is investigated by means of single molecule spectroscopy at room temperature. Individual trimers exhibit superradiance and loss of vibronic structure in emission spectrum, features proving exciton delocalization. [...]
