  2. 1. Extended Jaynes-Cummings Models In Cavity Qed

    Author : Jonas Larson; Stig Stenholm; Peter L. Knight; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Optics; Optics; Optik;

    Abstract : Due to the improvement within cavity quantum electrodynamics experiments during the last decades, what was former seen as 'toy models' are today realized in laboratories. A controlled isolated coherent evolution of one or a few atoms coupled to a single mode inside a cavity is achievable. READ MORE

  4. 2. Time dependent processes incavity QED

    Author : Jonas Larson; KTH; []
    Keywords : cavity QED; state preparation; non-classical; Jaynes-Cummings model; Fock state; measurement;

    Abstract : Cavity quantum electrodynamics (QED) has become one of themost successful tools for quantum information processing, butalso for the study of other pure quantum effects. In thisthesis we investigate one such system, the micromaser; an atomtraverse a cavity and interacts with the quantized modes of thecavity field. READ MORE

  5. 3. Ensembles and Open Quantum Systems in Polaritonic Chemistry

    Author : Eric Davidsson; Markus Kowalewski; Gerrit Groenhof; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polaritonic Chemistry; Open Quantum Systems; Cavity QED; The Jaynes-Cummings Model; Optical Cavities; Computational Quantum Dynamics; Theoretical Physics; teoretisk fysik;

    Abstract : Optical cavities are structures where excitations in the electromagnetic field (photons of light) are confined and generally long-lived. The spatial confinement will enhance interactions with any matter systems in the cavity, such that the behaviour of a combined system is best understood in terms of polaritonic states; mixtures of excitations in both light and matter.

  6. 4. Adiabatic Processes in the Janyes-Cummings model

    Author : Fredrik Mattinson; KTH; []
    Keywords : ;

    Abstract : This thesis investigates adiabatic processes in ageneralized Jaynes-Cummings model with two modes. Thenew ideais to use the bare states from this model for a stimulatedRaman adiabatic passage (STIRAP) process. In earlier work,atomic states have been used as quantum states to achieveadiabatic transfer in both theoretical and experimental work. READ MORE

  7. 5. A quantum for a quantum : Quantum simulators in exotic lattices

    Author : Pil Maria Saugmann; Jonas Larson; André Eckardt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum physics; condensed matter physics; quantum optics; optical lattices. Fock state lattices; exotic lattices; frustration; Theoretical Physics; teoretisk fysik;

    Abstract : This thesis centers on how to use exotic lattices in different ways to design potential quantum simulators. These exotic lattices are either real physical objects in the form of ultra cold atoms in  bipartite optical lattice systems or lattice models revealed in state space. READ MORE
