I've recently installed this library, and have run into an issue when trying to run the starter code ~~with GPU-accelerated Jax~~. For all solver resolutions except low, I get an operand dimension mis…

upon execution, I get the message
At line 341 of file /home/bdupe/Matjes/src/Hamiltonian_type/hamiltonian_collection.f90
Fortran runtime error: Index '1' of dimension 1 of array 'e' above upper bo…

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…

Again on the RT_integrators.
Can you please share here the math underlying the INV and RWA integrators?
I can't get the INV math from the suborutines.
The RWA puzzles me as it should not be a…

Dear ubermag team @fangohr @marijanbeg
1st Calculate Spin Current Density Js then Calculate Charge Current Density Jc
after this spin polarisation eficiency = Js/Jc

### What should we add?
I didn't find any built-in Hamiltonian simulation protocol in qiskit. So I'm thinking of building one according to the paper--Simulation Hamiltonian dynamics with a truncate…

The current HMC implementation handles constrained variables using the scheme described in "MCMC using Hamiltonian dynamics". (Section 5.1, p36.) I'm not convinced that this will always be correct. We…

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…

I'm doing open dynamics simulations with the density matrix represented as vectorized MPO as described in this [publication](https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.114.220601). The…
