# the effects of an ln-prime transformation to physical models

I have rather a "toy" type of modelling-problem that appeared to me along a book I am writing on number theory. I would be outmost thankful for any concrete or inspirational answers, including comments, examples, ideas, references and more and more:

By applying natual $ln$ to both sides of the canonical form of the fundamental theorem of arithmetic, it is simply possible to express any natural number $n\in \Bbb N$ in a linear combination as sum of weighted primes $p\in \Bbb P$:

$$\ln n=\sum_i m_i \ln p_i$$

In many ares of physics $n\in \Bbb N$ is often used to mark up states, harmonics...

In a storm of thoughts: how could we interpret a transformation of all $n\in \Bbb N$ in primes $p\in \Bbb P$ in different araes of physics. The composites will give place to primes, for instance: prime quantum states instead of n-states... What are theoretical modelling conseuqences? Could we comprehend things different or better?

Look foward for your many inspirations...

As you know, physicists often try to really calculate quantities. Indeed in physics you encounter sums of the form $\sum_n \ln n f(n)$, for example (where $f$ takes cares of the convergence). The problem here is that your $m_i$ and $p_i$ depend on $n$ (implicitly), so there is no simple way to input your formula in such a quantity. But maybe someone else has a more abstract idea. – Vibert May 26 '13 at 9:14
$n=e^{\sum_i m_i \ln p_i}$ helps? – al-Hwarizmi May 26 '13 at 9:17
That's not very different, right? ;) As an afterthought, in some cases mapping to primes can be useful, but in a strictly mathematical sense. Think of the Euler product for the zeta function or related identities. In some cases, a sum/product over primes might have better convergence properties than a sum over the integers. – Vibert May 26 '13 at 9:32
Looking just at the formula, I thought this is gonn be about entropy ... – Dilaton May 26 '13 at 9:47
But what if one could show that for instance a wave can be completely factorised in fundamental modes of prime frequencies $f(p)$? – al-Hwarizmi May 26 '13 at 10:53
