5.1. Short summary for input files of TeNeS

Input files of TeNeS are written in TOML format and each file has some sections. tenes_simple and tenes_std read some sections and generate an input file for tenes_std and tenes, respectively. tenes reads some sections and performs simulation.

For example, tenes_simple reads model and lattice sections and generates tensor, observable, and hamiltonian ones. Additionary, this copies parameter, correlation, and correlation_length sections.

The following table summarizes how each tool deal with sections.

Section	tenes_simple	tenes_std	tenes
parameter	copy	in / copy	in
model	in
lattice	in
tensor	out	in / copy	in
observable	out	copy	in
correlation	copy	copy	in
correlation_length	copy	copy	in
hamiltonian	out	in
evolution		out	in

• “in”

  • Tool uses this section as input

• “out”

  • Tool generates this section in output (= next input)

• “copy”

  • Tool copies this section into output (= next input)
