In what number of dimensions can hydrogen atom exist?

Question

We know that hydrogen does exist in N = 3 dimesional space.
The assumption is that photons are massless,
therefore flux is equal to the charge inside closed surface.

Answer 1

The hydrogen atom can exist in 2 or more spatial dimensions. It has been demonstrated that all 3-dimesional physics can be equivalently described mathematically in 2-dimensional physics. This is called the Holographic Principle. So the hydrogen atom or any other atom can exist at minimum in 2-d, but can also exist in more spatial dimensions (just as 2-d objects can exist in 3-d space).

Answer 2

Since it is three dimensional, the answer is the same... What photon are you talking about ?? There are none in hydrogen.
