this is a test entry1 for testing tests

This is a python test code:

import numpy as np

test0 = np.zeros(42)
test1 = np.ones(137)

This a nice Higgs Lagrangian for testing \( \LaTeX \) :

$$ \mathcal{L}_H = \left|\left(\partial_\mu -i g W_\mu^a \tau^a -i\frac{1}{2} g' B_\mu\right)\phi\right|^2 + \mu^2 \phi^\dagger\phi-\lambda (\phi^\dagger\phi)^2 $$

A pen test for testing a post-it photo:

Just some Markdown tests:

  • bold
  • italics

Some more test code from Julia Quantum Optics package:

using QuantumOptics
b = FockBasis(50)
a = destroy(b)
at = create(b)
H = 0.5*(a^2 + at^2)
psi0 = fockstate(b, 3)
tout, psit = timeevolution.schroedinger([0:0.25:1;], psi0, H)

using PyPlot
x = [-5:0.1:5;]
for i in 1:4
    subplot(2, 2, i)
    Q = qfunc(psit[i], x, x)
    pcolor(x, x, Q)
end
tight_layout()

It works!

It works?

This is a reminder for me in the future: _it **is possible** to have_ `markdown` inside `HTML` code blocks!!

Me, in the past.
