My initial intentions are to do some toy calculations in\npure gauge and theories with only squarks, as fermions are a tremendous pain-in-the-ass and lattice computations without them are really surprisingly simple.\n\nIdeally I'd like to write some really beautifully Julian code here, but my first attempt will probably be mainly practical.\n\nThis is a side-project being done in my free time and I may or may not decide to actually work on it.\n\n## References\nMy primary references have been [this nice primer](https://arxiv.org/abs/hep-lat/0012005) and these straightforward and accessible [lecture\nnotes](https://arxiv.org/abs/1410.3403).  Peter LePage's [tutorial](https://arxiv.org/abs/hep-lat/0506036) contains some practical advice on doing lattice\ncalculations for pure gauge theories and is also a useful reference for numerical computation of functional integrals in quantum theories more generally.\n\nIn addition see:\n\n- Z Fodor, C Hoelbling, \"Light Hadron Masses from Lattice QCD\", https://arxiv.org/abs/1203.4789\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fexpandingman%2Fcrystalballs.jl","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fexpandingman%2Fcrystalballs.jl","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fexpandingman%2Fcrystalballs.jl/lists"}
