Time evolution

First we create the coherent part based on .

Which results to:

for n in range(N):
    for m in range(N):
        idx1 = fidx(n,m,N)
        for q in range(N):
            idx2 = fidx(q,m,N)
            L[idx1][idx2] = L[idx1][idx2] -1j*J[abs(n-q)]
            idx2 = fidx(n,q,N)
            L[idx1][idx2] = L[idx1][idx2] +1j*J[abs(q-m)]
