### (More a feature removal request, actually)
Both `second_q.hamiltonians.hamiltonian.Hamiltonian` and `second_q.operators.SparseLabelOp` (and accordingly all their children) require a `.register_…

Please be as descriptive as possible, including: what is expected, why is this feature needed, what is the objective, etc.
### What is the feature being requested?

In yambo_rt there is one integrator named EXP
` ! 2 - Exp integrator: G(t+dt) = G(t) - i*dt *[H(t'),G(t)] - dt^2 *[H(t'),[H(t'),G(t)]] + .... [Can be expanded up to order 6]`

Hi,
I would have a feature request. (Would love to code it myself and PR, but, not being an expert, this would take me several days. Hoping you can help!)
Fermi runs HF with a simple interface. …

### Background
Dear developers,
Recently, I want to use our machine learning model [HamGNN](https://github.com/QuantumLab-ZY/HamGNN.git) to fit the SOC Hamiltonian matrix of ABACUS. I plan to use …

Dear Dr. Nafise Rezaei
We are working with the program obtaining very good results so far. Our next steps need the inclusion of two different terms in the hamilonian and we would like to know if thi…

In Yao, Hamiltonians are represented as general blocks. And `expect` function is implemented as `copy(st)' * apply!(st, H)`. It works perfect for pure states. But when using stabilizer tableau represe…
