Performing Thomas Fermi calculations of two dimensional electronic systems

ThomasFermi

Perform Thomas Fermi calculation to find the lowest energy density configuration of two dimensional electronic systems. See the ref paper for detail setup of the calculation.

Example usage

A detailed example of FQHE is given in a Jupyter notebook

from thomasfermi.FQHE import FQHE_TFdata
from thomasfermi.phi import *
from thomasfermi.algo import TF_engine

pars = {'L':20., 'l_B':7., 'd_t':30, 'd_b':30, 'dx':0.5, 'dy':0.5, 'Ec':5.85/40.}
data = FQHE_TFdata(pars)
pars = {'TFdata': data, 'Phi_EW_ext':-0.045, 'Phi_NS_ext':-0.015, 'Phi_back':-0.055}
Phi = make_QPC_Phi(pars)
pars = {'TFdata': data, 'Phi_ext':Phi.Phi_ext, 'n_iter':8}
engine = TF_engine(pars)

n = engine.find_local_opt(engine.init_n(eta = 0.3))
n = engine.find_opt(n0 = n, n_iter = 40)

Installation

thomasfermi can be installed via pip install thomasfermi.
