This code snippet calculates the matrix element of a local Hamiltonian on a bond, and so this does not relate with the boundary condition. TeNeS treats an infinite lattice by...

I close this because it has been one year since the last comment.

ありがとうございます、あとで置き換えておきます。 ついでに GHActions が走る環境を増やそうと思いつつ、 https://github.com/actions/virtual-environments に Ubuntu 22.04 が無くてなんでだろうと思ったらまだ4月になっていなかった…… (macOS は足しておきます)

手元で動くからなんでだろうと思ったら Apple Clang でした

https://github.com/issp-center-dev/TeNeS/actions/runs/2022274728 なんか通りましたね。謎。 verbose 付けてみます。

@wistaria GitHub Actions では通っていたのでよくわかりませんが、とりあえず doctest.h は更新しておきました。 （Ubuntu 22.04 でもそうだと書いてあるので違うとは思いますが、）もしかして M1-mac の話だったでしょうか……

TeNeS always treats tensors on a square lattice. Each tensor has four legs; left, top, right, and bottom. `self.sublattice.append(SubLattice([1, vd, vd, 1]))` means that the bond dimension of this site...

It seems to me that correlations along x-direction are absent. Could you show the bond dimensions of virtual bonds? If you set all the bond dimensions to `vd` (finite), what...
