Quantum Phase Transition in an Ion Trap
English This thesis considers the interaction between N ions confined in an ion trap and a set of laser fields, described by the Dicke model. The Dicke Hamiltonian for the two different models, used by the research group at the University of Innsbruck (the Quantum Optics and Spectroscopy group) and the Quantum Optics group at the National Institute of Science and Technology in Boulder, Colorado...
متن کاملIon motion synchronization in an ion-trap resonator.
Using a new type of ion trap, we demonstrate that the length of a packet of charged particles oscillating between two electrostatic mirrors will remain constant under special conditions. The effect can be understood in terms of phase synchronization, where, in a rather counterintuitive way, the repulsive Coulomb interaction between the ions actually holds the packet together. Application of thi...
متن کاملAn electrostatic autoresonant ion trap mass spectrometer.
A new method for ion extraction from an anharmonic electrostatic trap is introduced. Anharmonicity is a common feature of electrostatic traps which can be used for small scale spatial confinement of ions, and this feature is also necessary for autoresonant ion extraction. With the aid of ion trajectory simulations, novel autoresonant trap mass spectrometers (ART-MSs) have been designed based on...
متن کاملMicromotion Reduction and Barium-Ytterbium Ion Chains
The purpose of this REU project was to compensate for micromotion to reduce ion temperature and to trap and retain barium-ytterbium ion chains. Having cold ion chains allows us to implement quantum gates, which is a necessary component to any quantum computer. Micromotion is a constant issue that frequently needs to be compensated for because the electric fields within our trap are prone to dri...
متن کاملAn Ion Trap Interface for ESI-Ion Mobility Experiments
A method for improving the sensitivity of ion mobility measurements of ions generated from continuous ionization sources such as electrospray ionization is described. The method involves an ion trap interface between the continuous source and the pulsed experiment. The trap allows the electrosprayed ion beam to be accumulated between pulses of the mobility experiment and provides tightly focuse...
