Magnetic

This program calculates the chromomagnetic portion of the field strength tensor, i.e.

$B^{2} = - \sum_{i = 1}^{3} Tr (F_{j k} F_{j k})$

using a five-loop clover discretisation. The result is averaged over all lattice sites. The real trace of the three spatial field strength tensors $F_{23}, F_{21}, F_{12}$ are summed.

The code uses a toml as input file and tomlf to read it. The toml file must be of form

toml


fixNum = 2
fixLabels = ['G2L-8', 'G2L-36']

[fix.G2L-8]
gaugePath='conf/Gen2L/8x32/'
gaugeFormat='openqcd'
cfgList='conf/Gen2L/G2l_8x32.list'
NT=8
NS=32

[fix.G2L-36]
gaugePath='conf/Gen2L/36x32/'
gaugeFormat='openqcd'
cfgList='conf/Gen2L/G2l_36x32.list'
NT=36
NS=32

where the gaugePath is either the full or relative path to the directory containing the gaugefields, gaugeFormat is either openqcd or cssmILDG (for ILDG binary) and cfgList contains a list of the filenames of the gaugefield files, each on a separate line.

The application will read and produce $B^{2}$ for each gaugefield as well as the total plaquette, spatial and temporal plaquettes. It will perform a 1-remove jackknife analysis using FJSample and print for each 'label' in fixLabels. It will work for different numbers of fixLabels, and do each set sequentially.

Run using

fpm run magnetic -- mytoml.toml
