Rotation-electronic interaction in the 3p-complex Rydberg state of water
… for the rotational energy levels in a p-complex Rydberg state of an asymmetric top molecule of symmetry C2v. The effective Hamiltonian used consists of the usual rigid rotor Hamiltonian augmented with terms representing electronic spin and orbital angular momentum effects. Criteria for assigning …

The spectroscopy of bound and predissociating Rydberg states of NO in external electric fields
… of static and ramped electric fields to the Rydberg states of NO. Chapter 1 introduces the history of Rydberg states, their exotic properties, decay mechanisms, and the effect of an applied electric field. Chapter 2 details the experimental set-up used for the experiments presented in this …

Coherent atom-light interactions in multi-level systems
… resonances to absorbing resonances possible. Rydberg EIT is then introduced and is used to shown how the switching of such resonances using external electric fields in possible. The work then progresses towards the use of thin vapour cells to overcome the limitations of conventional systems. …

ELECTRIC FIELD IONIZATION OF SODIUM RYDBERG ATOMS
The outer electron of a Rydberg atom is so weakly bound to the atomic core that a relatively small electric field may cause the electron to be stripped from the atom. The field strength at which this ionization happens is strongly dependent on the state of the Rydberg atom. Pulsed electric field …

Spectra and dynamics of calcium monochloride
… an ideal molecule for studying molecular Rydberg states, as they are well described as by an ion-core containing two closed shell atomic ions (M2+,X-) and an unpaired electron. The spectra and dynamics of Rydberg states allows the testing of theories of electronic structure and …

The asymptotic expansion method for heliumlike ions
… of atoms with one electron in a highly excited state called a Rydberg state. The method was originally developed by Drachman from an expansion of the optical potential [7,81 for the Rydberg electron in powers of the perturbing potential and later reformulated by Drake based on a simple …

Coherent control of Rydberg atoms using sub-kHz linewidth excitation lasers
… for neutral atom quantum computing with Rydberg atoms. We describe the construction and characterisation of three continuous wave lasers stabilised simultaneously on a ultrahigh finesse Ultra-low-expansion (ULE) cavity, providing long-term stability and sub-kHz linewidth lasers with a …

Experimental demonstration of high-fidelity entanglement via Rydberg blockade
The strong dipole interactions of Rydberg atoms are ideal candidates to facilitate interactions between neutral atoms to generate entanglement for quantum information processing. This offers the potential to scale to large atom arrays through well established techniques for neutral atoms, …

Ultralong range Rydberg molecules : investigation of a novel binding
… scattering. These molecules are composed of a Rydberg atom and a ground state atom - here Rb(ns) and Rb(5s) - where the binding arises from scattering of the Rydberg electron from the ground state atom. The ground state atom is bound to the Rydberg wavefunction, which has radii on the order of …

Development of Optoelectronic Devices and Computational Tools for the Production and Manipulation of Heavy Rydberg Systems
… and manipulation of novel atomic and molecular states. The design, construction and characterization of a driver for an acousto-optic modulator is presented which achieves a maximum diffraction efficiency of 54 % at 200 MHz, using a commercial modulator. A novel design is presented for a highly …

Towards the formation of a forward-boosted beam of neutral antihydrogen for gravitational studies
… a positronium atom (Ps) (which is the bound state of an electron and a positron) and an antiproton: in the reaction, the electron is swapped with the antiproton, and the antihydrogen atom is thus formed. The AE ̄gIS experiment is located at the European Organisation for Nuclear Research …
