docutils 0.9 knows how to do syntax highlighting. With docutils 0.8 there seems
to be no way. But we can do this::
import math
import cmath
import numpy
from matplotlib import pyplot
import kwant
from kwant.contrib.digest import gauss
def hopping(site0, site1, phi):
x0, y0 = site0.pos
x1, y1 = site1.pos
return -cmath.exp(-0.5j * phi * (x0 - x1) * (y0 + y1))
def onsite(site, phi):
return 0.05 * gauss(repr(site)) + 4
def make_system(L=50):
def central_region(pos):
x, y = pos
return -L < x < L and \
abs(y) < L - 37.5 * math.exp(-x**2 / 12**2)
lat = kwant.lattice.square()
sys = kwant.Builder()
sys[lat.shape(central_region, (0, 0))] = onsite
sys[lat.nearest] = hopping
sym = kwant.TranslationalSymmetry((-1, 0))
lead = kwant.Builder(sym)
lead[(lat(0, y) for y in range(-L + 1, L))] = 4
lead[lat.nearest] = hopping
sys.attach_lead(lead)
sys.attach_lead(lead.reversed())
return sys.finalized()
def lesser_gf(sys, args):
wf = kwant.solvers.default.wave_function(sys, 0.15, args=args)
return (abs(wf(0))**2).sum(axis=0)
sys = make_system()
kwant.plotter.map(sys, lesser_gf(sys, args=[1/40.0]))

kwant - Quantum transport simulation
====================================
kwant is a Python package for numerical quantum transport calculations. It aims
to be an user-friendly, universal, and high-performance toolbox for the
simulation of physical systems (of any dimensionality and geometry) that can be
described by a tight-binding model. kwant has been designed such that the
natural concepts of the theory of quantum transport (lattices, symmetries,
electrodes, orbital / spin / electron-hole degrees of freedom) are exposed in a
simple and transparent way: Defining a new simulation setup is very close to
describing the corresponding mathematical model. kwant offers direct support
for calculations of transport properties (conductance, noise, scattering
matrix), dispersion relations, modes, wave functions, various Green's functions,
and out-of-equilibrium local quantities (charge or current densities). Other
computations involving tight-binding Hamiltonians can be implemented easily
thanks to its extensible and modular nature.
