In https://qiskit.org/ecosystem/dynamics/tutorials/Rabi_oscillations.html the relationship between the `hamiltonian_operators`, the `signals` passed to the solver and the time-dependent term in the Ha…

I added both the easy-plane anisotropy Dz and easy-axis anisotropy Dx in the magnetic Hamiltonian.
AFM.addmatrix('value',diag([Dx 0 Dz]),'label','D','color','black') (Dx0)
But the symbolic solution…

As seen by
```
g = graphs.StarGraph(3)
print(g.hamiltonian_path())
print(g.hamiltonian_cycle())
```
there is a difference in function behaviour. Unify them. First wait few days and see if there is…

Sometimes we need to deal with time-dependent Hamiltonian(eg. the effective Hamiltonian in Hierarchy of Matrix Product States). I have tried two methods, but each of them has some drawbacks.
1. Devid…

In cases where the Hamiltonian is constructed with 2 states per site and the user requests no symmetries (e.g. just particle conservation at the most), it should be possible to construct a Hamiltonian…

Dear YangZhong,
I am writing to you regarding a memory issue I am encountering while calculating the band structure of a system with 3903 atoms using `band_cal_parallel.py`. With parameters set to …

### What feature should we add?
An integral step into achieving Issue #213 is to be able to have protocols which generate unitaries of time-dependent Hamiltonians over some user-defined interval.

It appears that most of the code needed to perform a fit on source weights, spectral index and number of source weights is already included in the `flarestack.core.minimisation.FitWeightMinimisationHa…
