For reference, there are other packages that also provide wrappers for multiple eigensolvers: - https://github.com/rveltz/BifurcationKit.jl/blob/master/src/EigSolver.jl - https://github.com/pablosanjose/Quantica.jl/blob/master/src/diagonalizer.jl But I think it would be beneficial to have separate package just devoted...

If we rotate the system, the `ham` is not transformed (or is) depending on whether we are also rotating the reference frame (or not) with respect to which the orbitals...

>If the orbital types are known, can this be done automatically simply knowing the real-space f? Or does the user need to also provide a second transformation for the wannier...

I am not sure that having a single BlockHamiltonian type would be the best approach. Instead of seeing all these cases as problems of coupled Hamiltonians, I think we should...

I will start with the Wide-Band Limit (WBL) case: Indeed, in principle, I think it would be possible to consider a WBL self-energy as a subtype of `AbstractHamiltonian`. Although it...

I think there is some convergence going on and I like the new proposal, but a crossing might have occured. I do think you are correct in saying that the...

One more data point: The pi-flux model, which contains Dirac points at `(pi, pi/2)` and `(pi, -pi/2)` and can be defined in Quantica by: ``` latPiFlux = lattice( sublat((0, 0),...

As an alternative, wouldn't it be possible to create a am empty TightBindingModel and then incrementally add new terms, using the hopping algebra. For example: ``` model = tbmodel() #...
