Rydberg States Exhibiting Quantum Defect?

In summary, the speaker is seeking references for Rydberg states that exhibit the quantum defect, where the attractive force between the nucleus and valence electrons increases as the penetration of the valence electron into the core increases. They also ask for examples of atomic systems that demonstrate these behaviors. The person is looking for comprehensive discussions on these topics and suggests searching on Wikipedia for more information.

I am posting this to see if any readers/mentors, etc. can refer me to any type of reference for Rydberg states that also exhibit the quantum defect wherein we need to be concerned with the attractive force between the nucleus (or possibly, the ion core) and valence electrons as the penetration of the valence electron into the core increases. The net result is the valence electron sees a greater positive charge.

Additionally, can you mention a specific atomic system exhibiting these seemingly contradicting behaviors? That is, Rydberg states grow in size whereas the quantum defect would appear to be observed in systems with smaller orbits than those of Rydberg states.

Thanks for your input. I am looking for thorough, seminal or heuristic discussions on these topics.

1. What are Rydberg states exhibiting quantum defect?

Rydberg states are highly excited electronic states of an atom or molecule, characterized by a large principal quantum number. The quantum defect refers to the deviation of the energy levels in these states from the simple Rydberg formula, due to the influence of the atomic core and neighboring electrons.

2. What is the significance of studying Rydberg states exhibiting quantum defect?

Studying Rydberg states exhibiting quantum defect is important for understanding the behavior of atoms and molecules at high energies and in complex systems. It also has applications in fields such as astrophysics, quantum optics, and quantum information processing.

3. How are Rydberg states exhibiting quantum defect experimentally observed?

Rydberg states exhibiting quantum defect can be observed experimentally through a variety of techniques, such as laser spectroscopy, microwave spectroscopy, and photoionization. These methods allow for the measurement of energy levels and other properties of these states.

4. What are some factors that affect the quantum defect in Rydberg states?

The quantum defect in Rydberg states can be influenced by factors such as the electron-electron interactions, the presence of neighboring atoms or molecules, and the spin of the electron. These factors can cause deviations from the simple Rydberg formula and affect the energy levels of these states.

5. How do Rydberg states exhibiting quantum defect play a role in quantum computing?

Rydberg states exhibiting quantum defect have been proposed as a potential platform for quantum computing due to their long coherence times and strong interactions. These states can be manipulated and controlled using laser pulses, making them promising candidates for quantum information processing tasks.
