@author: pab

class ClassicalHamiltonian

Bases: object

Hamiltonian

Parameters:

nscalar

number of ions in the chain

wscalar

angular trap frequency

Cscalar

Coulomb constant times the electronic charge in SI units.

mscalar

the mass of a single trapped ion in the chain

initialposition()

Defines initial position as an estimate for the minimize process.

normal_modes(eigenvalues)

Return normal modes

Computed eigenvalues of the matrix Vx are of the form

(normal_modes)**2*m.

potential(positionvector)

Return potential

Parameters:

positionvector: 1-d array (vector) of length n

positions of the n ions
