Scattering of array of spheres, scalar theory

Project description


Package for solving the scalar wave equation with a linear array of scattering spheres. Possibility to solve for constant potential well and hard spheres i.e. infinite potential.


pip install pyScatSpheres

The installation requires external system based installations :

  • Fortran compiler : to run external library py3nj
  • optional tex compiler : necessary for the figures to be displayed in latex text.

Those packages can be installed on linux with

  • apt-get install gfortran
  • apt-get install tex-live

Using the GUI

A gui is available to interactively display pre calculated solutions.

import os
from pyScatSpheres import gui_base as hsa_gui

#fetch built-in solution
hsa_e = hsa_gui.GUI_handler(df_path)

Using the API

New sets of solution can be calculated and solved to a pickle using the API.

import numpy as np
import pandas as pd
from pyScatSpheres import qdot_sphere_array as qsa
from pyScatSpheres import glob_colors as colors

kas = [0.5,2,5]
kds = [2,5,10]
kps = [1.2]
kas,kps,kds = np.meshgrid(kas,kps,kds)
kas,kps,kds = kas.flatten(),kps.flatten(),kds.flatten()
cols = ['N','ka','kp','kd','nmax','sigma','ap','bp']
df = pd.DataFrame(columns=cols)
for ka,kp,kd in zip(kas,kps,kds):
    nmax = max(int(np.ceil(1.3*ka)),int(ka)+4)
    s = qsa.QdotSphereArray(N=N,ka=ka,kp=kp,kd=kd*ka,nmax=10,solve=1,copt=1)
    sig = s.get_s(npts=1000)
print('DataFrame saved:\n'+
