5.2.1. Make an input file for a lattice¶
In PMWA, as a simple tool lattgene_P is prepared for generating a lattice definition file lattice.xml for a standard model. In this section, the usage of
lattgene_P is explained.
lattgene_P 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_P 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_P 2 4 4 10.0 1 1 0
