Dear Johannes,

That is perfect, thank you! I now understand, and am able to implement my desired couplings. Thanks very much for your helpful advice.

Kind Regards,
Jack Stevens.

Dear Johannes, As predicted, I'm having some trouble with the self.group_sites option, specifically where to call it in my model class. Below is the code that initialises my model class Iomin_Model(CouplingMPOModel, NearestNeighborModel): """Implementation of the 4-site Iomin Hamilton...

Dear Johannes, Thanks for your quick and detailed reply, I've implemented those changes and now have a much cleaner model defined. I'm going to go for the implementation of the SpinChainNNN example, and I'm sure I'll be back soon with questions about the implementation of the couplings. Thanks very ...

Hi there, I'm trying to implement my own model and run TEBD on it with non-nearest neighbour interactions. To do this, I've split my lattice into unit cells of 4 sites, which then are all nearest-neighbour (the sites are hardcore bosons, which I've created by simply removing the JW entries in the Fe...
