How to understand the hydrogen energy level and its wave function?

I have difficulty to understand this Hydrogen atom's energy level and its wave function. My difficulty is regarding the hydrogen atom itself, not the energy level and the wave function their selves, ...

What system has a spectral series in the radio spectrum?

As an electron energy level has an emission level depending upon the excitation, is it possible for a system such as a Rydberg atom to have emissions in the low side of the frequency range?

Formula for wavelength emitted taking into account the quantum orbital number $l$

Rydberg's formula can be used to find the wavelength emitted due to an electron moving from one energy level $n_i$ to another one $n_f$. But when the Schrödinger's model of the atom is introduced we ...

Nodes in Spherical Harmonics

In Rydberg Atoms book by Thomas F. Gallagher, Page 14, the author provides the general equation of spherical harmonics which is well-known. He states that there exist $l-m$ nodes in the $\theta$ ...

Schrodinger Equation of a Hydrogen Atom in a Rydberg State

I am not a mathematician, so I really appreciate it if someone could explain it in a simple way. In Rydberg Atoms book by Thomas F. Gallagher, the Schroedinger equation for the H atom in atomic units ...

How can you explain long lifetime of the Rydberg atoms? [duplicate]

Long lifetimes of the Rydberg atoms seems counterintuitive to me. Intuitive explanation: the higher electron was excited, the more levels below became available for spontaneous decay. So the first ...

Why is EIT needed to story memory using rydberg atoms?

I was going through a paper explaining how the write-in and read-out efficiencies can be increased using cold atoms where they used Rydberg atoms, and mentioned that they were probed using EIT(...

Why does the read-out efficiency increase when coupling an atomic ensemble to an optical cavity?

I went through a paper where it mentioned that the read-out efficiency of a quantum memory would be increased by coupling the atomic ensemble with an optical cavity. I think rydberg atoms were used to ...

How to explain the long lifetime of Rydberg atoms with Fermi golden rule?

How to explain the long lifetime of Rydberg atoms with Fermi's golden rule? Wikipedia says it is partly due to tiny wavefunction overlap with inner orbitals, but what about the outer ones?

What's the highest-$n$ Rydberg state that's been created and detected experimentally?

Rydberg states form an infinite series of electronic states that asymptotically approach the ionization potential of the atom or molecule, usually in good agreement with the simple Rydberg formula. ...

What is the highest energy level an electron can reach and still tend to move to a lower state and still "belong" to the atom?

For example, imagine that I excite an electron in order to move it to the 19th energy level (when the lowest possible is, let's say, the 2nd (there are three electrons in total in the atom)). How can ...
