https://figshare.com/articles/journal_contribution/Unitary_gauge_considered_harmful/963540
A bit dated now, partially superseded by Higgs discovery, new observational data, additional analysis and numerical results described in "The Forgotten Landscape". Still worth reading.
Abstract: I informally review the Higgs mechanism, focusing on fundamental aspects which should be common knowledge but apparently are not, explain why your understanding of gauge symmetry breaking is a decreasing function of your reliance on the unitary gauge, and discuss some implications for cosmology (domains, dark energy, CMB cold spot).Cosmology, Particle Physics2014-03-17 17:43:10Gradient and smoothing stencils with isotropic discretization error
https://figshare.com/articles/journal_contribution/Gradient_and_smoothing_stencils_with_isotropic_discretization_error/963539
Gradient stencils with isotropic O(h^2) and O(h^4) discretization error are constructed by considering their eff?ect on common, rotationally invariant building blocks of field-theoretic Lagrangians in three dimensions. The same approach is then used to derive low-pass ?filters with isotropic O(h^4) and O(h^6) error.Computational Physics, Numerical Analysis2014-03-17 17:24:56The Forgotten Landscape

Essay as originally posted on FQXi, August 31, 2012 (http://fqxi.org/community/forum/topic/1462). Abstract:
Contrary to common lore, the standard model of particle physics has a “landscape” of physically inequivalent vacua, most of them quite different from ours. I discuss some cosmological consequences and related observational constraints, show how non-perturbative electroweak dynamics selects our special vacuum, and put an old idea to rest.Cosmology, Computational Physics, Particle Physics2014-03-17 16:28:00HaNLON
https://figshare.com/articles/software/HaNLON/963473
HaNLON is a package of C++ libraries and programs used to simulate the dynamics of electroweak interactions in the really low energy limit. The physics is a straightforward application of effective field theory to the standard model of electroweak interactions, so needless to say it's crackpot material which will get you banned from astro-ph, should anyone catch you with it.Cosmology, Computational Physics, Particle Physics2014-03-17 16:17:16
