Exploring the 3D Ising gauge-Higgs model in exact Coulomb gauge and with a gauge-invariant substitute for Landau gauge
Michael Grady
The Z2 gauge-Higgs model in three dimensions has two different types of phase transition, confinement-deconfinement and Higgs magnetization. Here they are explored through two orde…
Solution to the gauge-Higgs analyticity paradox
Michael Grady
The Fradkin-Shenker theorem proves analyticity in a region that connects Higgs to confinement regimes, precluding a phase transition. This conflicts with a simpler analyticity argu…
Direct evidence for a Coulombic phase in monopole-suppressed SU(2) lattice gauge theory
Michael Grady
Further evidence is presented for the existence of a non-confining phase at weak coupling in SU(2) lattice gauge theory. Using Monte Carlo simulations with the standard Wilson acti…
Toward a proof of long range order in 4-d SU(N) lattice gauge theory
Michael Grady
An extended version of 4-d SU(2) lattice gauge theory is considered in which different inverse coupling parameters are used, for plaquettes which are purely spaceli…
Is SU(2) lattice gauge theory a spin glass?
Michael Grady
A new order parameter is constructed for SU(2) lattice gauge theory in the context of the two-real-replica method normally used for spin glasses. The order parameter is sensitive t…
Exploring Residual Gauge Symmetry Breaking
Michael Grady
Simulations of pure-gauge SU(2) lattice gauge theory are performed in the minimal Coulomb gauge. This leaves a residual or remnant gauge symmetry still active which is global in th…
Reconsidering gauge-Higgs continuity
Michael Grady
The 3-d Z(2) lattice gauge-Higgs theory is cast in a partial axial gauge leaving a residual Z(2) symmetry, global in two directions and local in one. It is shown both analytically…
Critical or tricritical point in mixed-action SU(2) lattice gauge theory?
Michael Grady
An analysis of scaling along the first-order bulk transition line in fundamental-adjoint SU(2) lattice gauge theory strongly supports the first-order endpoint being a tricritical p…
Do Large Abelian Monopole Loops Survive the Continuum Limit?
Michael Grady
An analysis of the monopole loop length distribution is performed in Wilson-action SU(2) lattice gauge theory. A pure power law in the inverse length is found, at least for loops o…
Monopole Loop Distribution and Confinement in SU(2) Lattice Gauge Theory
Michael Grady
The abelian-projected monopole loop distribution is extracted from maximal abelian gauge simulations. The number of loops of a given length falls as a power of the length nearly in…
Deconfinement from Action Restriction
Michael Grady
The effect of restricting the plaquette to be greater than a certain cutoff value is studied. The action considered is the standard Wilson action with the addition of a plaquette r…
Can a Logarithmically Running Coupling Mimic a String Tension?
M. Grady
It is shown that a Coulomb potential using a running coupling slightly modified from the perturbative form can produce an interquark potential that appears nearly linear over a lar…
