Re: Applying different time evolution to different subsystems with TEBD
Hi, This can not be done out of the box. TEBD will also be difficult, since your gates are not nearest neighbour (even if H_i are NN on their subsystem, they are NNN on the full system). You could force TEBD by grouping sites to a nearest neighbour model. I would go for MPO time evolution though. Yo...

Re: Matrix representation of dN operator
Yes, you can have a look at the operator in the site In [3]: import tenpy as tp In [4]: site = tp.FermionSite(filling=0.5) In [5]: site.dN Out[5]: <npc.Array shape=(2, 2) labels=['p', 'p*']> In [6]: site.dN.to_ndarray() Out[6]: array([[-0.5, 0. ], [ 0. , 0.5]]) In[7]: # The basis is { |empty> , |ful...

Re: Issue in running chiral_pi_flux.py
Hi,
Yes it turns out those examples are not yet updated for v1.0.
They should run with v0.99.
Working on a fix in https://github.com/tenpy/tenpy/pull/400.
Thanks for posting!
