Helium Stark Animate

Create animations of the Rydberg electron charge distribution in helium as a function of electric field using the Numerov method.

Install

Install helium-stark-animate using setuptools,

git clone https://github.com/axm108/helium-stark-animate
cd helium-stark-animate
python setup.py install

Install helium-stark-zeeman using setuptools,

git clone https://github.com/axm108/helium-stark-zeeman
cd helium-stark-zeeman
python setup.py install

Basic usage

Import libraries,

from heliumstarkanimate import HeliumStarkAnimator
from hsz import HamiltonianMatrix
import numpy as np

Instantiate HamiltonianMatrix object,

n_min = 5
n_max = 6
S = 1
ham = HamiltonianMatrix(n_min=n_min, n_max=n_max, S=S)

Instantiate HeliumStarkAnimator object,

animator = HeliumStarkAnimator(ham)

Calculate charge distributions of a state for different values of the electric field,

state_idx = n_min**2
Efield = np.linspace(0.0, 6.0*10**5, 11) # V/cm
charge_dists = animator.charge_distributions(state_idx, Efield*1e2)

Plot the charge distribution for one field,

animator.plot(charge_dists[0])

Save the charge distributions to a .jpg file for each field,

animator.save(charge_dists)

Plot an interactive figure of the charge distribution along with the corresponding Stark map,

animator.plot_interactive(Efield, charge_dists, stark_map, state_idx)
