It appears as if the step of `Diagonalizing the two-particle Hamiltonian` in the exact FAA approach for the self-energy is currently only running in serial. Seen both with `gcc` and native `Eigen` bac…

First, thank you for this awesome package as well as the documentation. I went through it today and learned quite a few things!
I am not particularly sure if the below is an issue or not, but here…

Hello, we are trying to check the Bose-Hubbard model for some trivial cases using the NetKet implementation of this model and the example code provided. For example for 0 hopping and just 1 boson we e…

@scemama is there a way to compute the PT2 deterministically in QP2?
In our tests, are we comparing to the stochastic PT2 value?

Hi all,
I found a strange convergence issue of DMRG, which I wanted to share with you.
At the moment I'm not sure where it comes from, and I'm investigating it further.
The problem occurs even in t…

Dear Colleagues
I am very much interested in making use of mrchem.
However I cannot compile libgetkw on ubuntu 18-10!
I proceeded as follows.
I cloned MRchem , MRcpp and libgetkw from their …

The point we hope to make is that we can implement the single-particle hamiltonian with an nstep derivative. But we need to be extremely careful---if we define the kinetic energy for each particle wi…

I'm setting up the exact diagonalization of a heisenberg model with external fields.
The definition of the model:
```
totalSz = 1
L =8
sigmaz = np.array([[1,0],[0,-1]])
pars['Hilbert'] = {
