### Is this hamiltonian of the form of some well-known physical system?

One likely candidate for what they "want you to say" is a Kepler potential (i.e. produced by an inverse distance-squared force) viewed in a rotating frame that scales the rotation rate by a ...

### Can a primary constraint contain spatial derivative of the field?

Yes, in field theory the primary constraints can contain spatial$^1$ derivatives of the canonical fields. One example is when Legendre transforming the Nambu-Goto (NG) string action, see e.g. this ...

### Spin Orbit Coupling Hamiltonians

No, these are not always the same thing. Spin-orbit coupling in atoms Spin-orbit coupling can be derived by reduction of the Dirac equation to non-relativistic limit, as one of several relativistic ...
