I'm very sorry for the late reply. TeNeS searches for the ground state by using an iterative method (imaginary time evolution) and hence the initial state affects the result, particularly...

The easiest way to prepare required libraries is to use apt: `sudo apt install liblapack-dev`. If you want to use MPI, `openmpi-bin` and `libopenmpi-dev` are required. FYI, HPhi is available...

Did you install HPhi via apt? If so, just type `HPhi -s input_file_name`.

TeNeS uses [mptensor](https://github.com/smorita/mptensor) for handling tensors, and so save/load tensors by using [mptensor's functionality](https://github.com/smorita/mptensor/blob/master/include/mptensor/file_io/save.hpp). As an example, let's consider a bulk tensor `T_ltrbp` (indices mean left, top, right, bottom, and...

TeNeS considers infinite lattice by assuming translational symmetry with periods L and W. https://issp-center-dev.github.io/TeNeS/manual/master/en/html/algorithm/algorithms.html L and W are the size of the unitcell.

Both `z` (old) and `zs` (new) mean the number of bonds connected to a site. While `z` treats only the nearest neighbor bonds, `zs` does 2nd and 3rd neighbors too....

1. In the main part of `tenes_simple` script, the function `tenes_simple` is called as https://github.com/issp-center-dev/TeNeS/blob/f5c35c58b6aeebbcbdd8007d0dfb92412283c9d7/tool/tenes_simple.py#L1360 Thus, the change of the default value of the second argument `use_onesite_hamiltonian` of `tenes_simple` function...
