Cooling and Cooperative Coupling of Single Atoms in an Optical Cavity
Reimann, René (2014-11-26)In this work the motional state of single cesium atoms strongly coupled to an optical high-finesse cavity is controlled and manipulated by a novel Raman cooling scheme. Furthermore, cavity-modified super- and subradiant ... -
Dynamik und Korrelationen eines Bose-Einstein-Kondensats aus Licht
Schmitt, Julian (2016-02-02)Einer der bemerkenswertesten Aspekte der Bose-Einstein-Kondensation ist die natürliche Ausprägung von Korrelationen und langreichweitiger Ordnung in einem System, welches sich im thermischen Gleichgewicht befindet. ... -
Internal and external dynamics of a strongly-coupled atom-cavity system
Reick, Sebastian (2010-01-07)A system comprised of a small number of neutral atoms coupled to the mode of a high finesse optical resonator is a model system to study light-matter interaction at the quantum level and to explore fundamental effects like ... -
A neutral atom quantum register
Schrader, Dominik (2005)In this thesis I present the realization of a quantum register of single neutral atoms, which is a building block of a quantum computer. It consists of a well known number of "qubits" - the quantum analogs of classical ... -
Optical control of single neutral atoms
Alt, Wolfgang (2004)This thesis presents experiments concerning the preparation and manipulation of single neutral atoms in optical traps. The experimental setup as well as the properties of the optical dipole trap are described. The examination ... -
Optimal quantum control of atomic wave packets in optical lattices
Peter, Natalie (2019-05-24)In this work, I investigate the motional control and the transport of single neutral atoms trapped in an optical conveyor belt. The main goal is to prepare the atoms in the vibrational ground state of the trapping potential ... -
Parametric excitation of the quantum vacuum in nonlinear optical resonators
Langerfeld, Thorsten Friedrich (2022-07-25)In this thesis, I present the generation of correlated photon pairs in high-finesse nonlinear optical micro-resonators. In a first attempt, we utilize the third-order nonlinear material polarization of the dielectric mirror ...
