Rydberg atoms thesis

We explain how entanglement and quantum measurement enable the jumps, which are otherwise classically forbidden. We compare the inter- actions between series and between atoms, highlighting the importance of certain series for applications suggested in previous works.

We consider a one- dimensional lattice of strontium atoms, and find that the internal dynamics of the Rydberg atoms demonstrates spin transport for large lattice spacings and a separation of the spin and total angular momentum dynamics for small lattice spacings.

All relevant data are within the paper and its Hauptseminar: We extend the MQDT formalism to the description of the natural radiative lifetimes of strontium, where the perturbers are found to have a large quenching effect on these lifetimes.

There are three phases: Rydberg atom — WikipediaA Rydberg atom is an excited atom with one or Rydberg atoms thesis electrons that have a very high principal quantum number.

The paper purports to be about a detection method, Atomic thesis — Raw ConfessionsAtomic thesis. Then we consider the dynamics of the quantum model when mean-field theory predicts bistability. This thesis explores the latter.

Quantum nonequilibrium physics with Rydberg atoms

Spin-angular momentum separation analogous to spin-charge separation in condensed matter in strontium Rydberg atoms may have uses in the investigation of one-dimensional Fermi gases and their description using Luttinger liquid theory.

This thesis explores the latter. Finally, we let each atom be laser-excited to a short-lived excited state in addition to a Rydberg state. By taking the one active electron approximation we develop consistent models of these long- range interactions, and construct a survey of the Rydberg state dipole-dipole interactions and quadrupole-quadrupole interactions.

We consider a lattice Rydberg atoms thesis atoms, laser-excited from the ground state to a Rydberg state and spontaneously decaying back to the ground state. The growing use of Rydberg states in the field of cold atoms necessitates a more detailed understanding of the effects of dipole-dipole interactions, which are currently being investigated in a number of research groups worldwide.

Especially the sensitivity of Rydberg atoms to microwave and THz radiation makes this a promising system for sensing applications. TheQuantum nonequilibrium physics with Rydberg atoms A Rydberg atom is an atom excited to a high energy level, and there is a strong dipole-dipole interaction between nearby Rydberg atoms.

Over time, the system occasionally jumps between a state of low Rydberg population and a state of high Rydberg population.

Rydberg atoms Research Papers — Academia. This three-level configuration leads to rich spatiotemporal dynamics that are visible in the fluorescence from the short-lived excited state. Posted Mar 2, by anonymous and P. In order to include two-electron effects in the description of dipole-dipole interactions in divalent atoms, we use multichannel quantum defect theory MQDT to develop models of the Rydberg series of strontium.

These atoms have a number of peculiar properties First observations of Rydberg blockade in a frozen gas of This thesis details the first measurements of Rydberg dipole blockade in a cold ensemble of divalent atoms. We use an empirical reactance matrix formalism, where the reactance matrix is fitted to reproduce experimentally measured values of the bound state energy levels.

Long-Range Interactions in One- and Two-Electron Rydberg Atoms

While there has been much interest in closed systems of Rydberg atoms, less is known about open systems of Rydberg atoms with spontaneous emission. While there has been much interest in closed systems of Rydberg atoms, less is known about open systems of Rydberg atoms with spontaneous emission.

By incorporating the MQDT description of the Rydberg states of strontium into the calculation of dipole-dipole interactions, we find a spin-forbidden two-atom resonance in the 3D2 states of strontium.

Trona F, Weniger Data Availability: The atoms develop strong spatial correlations that change on a long time scale.

In the second part of the thesis a new apparatus for metastable production and Stark recurrence spec-troscopy is introduced, known as the Portable Rydberg Generator.

Calculations of long-range interactions in Rydberg states of caesium, cal- cium, rubidium, strontium and ytterbium are presented.
