Hello (and sorry for this stupid question),

Could someone tell me the name of this Hamiltonian

[tex] H = \left(\dfrac{p^2+q^2}{2}\right)^2 [/tex]

Thanks in advance

I'm just looking for the name that is called in the scientific literature. I am not looking for the Hamiltonian theory.

In the article, it shows a specific hamiltonian similar to yours and relates it to a "Heisenberg group" under the topic Sub-Riemannian manifolds.

Its unfortunate that the URL didn't directly jump there as expected.

Or maybe this one:

Example 5 (Henon–Heiles problem)
The polynomial Hamiltonian in two degrees of freedom
is a Hamiltonian differential equation that can have chaotic solutions.

Figure 1 shows a regular behaviour of solutions when the value of the Hamiltonian is small,and a chaotic behaviour for large Hamiltonian.

Ok, Thank you jedishrfu.

However, there are subtle differences between these two Hamiltonians. "My" can be thought of as the Hamiltonian of the harmonic oscillator squared:

[tex] H = H_{HO}^2 [/tex]

where

[tex] H_{HO} = \dfrac{1}{2}(p^2+q^2) [/tex].
