6.2.1. Make an input file for a lattice¶
In PMWA, as a simple tool lattgene is prepared for generating a lattice definition file lattice.xml for a standard model. In this section, the usage of
lattgene is explained.
lattgene generates a lattice definition file for a cubic lattice.
The parameters to be specified are as follows.
| Parameter | type | Remarks |
|---|---|---|
| D | int | The dimensions |
| L | int | The size of the lattice (specified for each dimension consecutively) |
| B | double | The inverse temperature |
| NLdiv | int | The number of divisions of L (divide NLdiv for each dimension) |
| NBdiv | int | The number of divisions of L |
| NFIELD | int | The type of magnetic field (basically set to 0) |
Examples of use are described below.
One-dimensional 8-sites chain, inverse temperature 10.0, definition of lattice file when division number is 1:
$ lattgene 1 8 10.0 1 1 0Two dimensional 4*4 sites lattice, reverse temperature 10.0, definition of lattice file when division number is 1:
$ lattgene 2 4 4 10.0 1 1 0
