Discreteness of bound vs unbound states • Physics Forums

I don''t think discreteness is a question of boundary conditions, nor whether the wave function can extend to infinity. Consider an isolated hydrogen atom: there''s nothing

What is discreteness of language?

Discreteness: Language is made up of discrete units like sounds or words. Duality: Language has both a surface level (sounds) and a deeper level (meaning).

Discreteness of Electron Orbits: Elliptical Shapes?

We know that orientations of electron orbit are discrete, what exactly do you mean by discreteness,& also is there any particular shape of orbits like an ellipse ?

Discreteness"+" Compactness= Finiteness: What does this

So the further away from discreteness we get, the more likely we are to be compact, in a precise sense! How does compactness generalize finiteness? This is ultimately

How does LQG handle discreteness?

In LQG it is used at a fundamental level (model building) whereas in other approaches it seems to be a kind of emergent phenomenon (in string theory nearly all

Discreteness and gap in spectrum

Discreteness is attributed to discontinuous evolution of eigenvalues on the spectrum of an operator. A spectral gap, is the distance between two disjoint points on the

Assessing discreteness of the random variable by its

It is easy to spot a discrete integer valued random variable by looking at its characteristic function, as that is periodic with period $2 pi$, i.e. for binomial distribution it is
