overhead of creating tvdp engines
I want to code a step-wise Floquet drive using tdvp. Since I will be switching between two MPO-Hamiltonians, the pedestrian solution would be to create a tdvp engine every time evolution step, which also instantiates the engine class every time step. I was wondering if this will result in unnecessar...

single honeycomb cell from the honeycomb lattice class
Is it possible to adjust the boundary conditions for the Honeycomb lattice class, such that it models a single honeycomb cell containing 6 lattice sites? I was thinking that since a single honeycomb cell contains exactly three unit cells (with the appropriate bc) this might be doable with the curren...

TDVP for MPO which is not nearest-neighbor w.r.t. MPO index
Hi Johannes, I'd like to follow up on your explanation in github: This issue is not a bug of TeNPy, it's a limitation of TDVP trying to keep the MPS bond dimension fixed and starting from a product state. While SingleSite TDVP strictly keeps the MPS bond dimension fixed, two-site TDVP can increase i...
