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…
Connecting phase transitions between the 3-d O(4) Heisenberg model and 4-d SU(2) lattice gauge theory
Michael Grady
SU(2) lattice gauge theory is extended to a larger coupling space where the coupling parameter for horizontal (spacelike) plaquettes, , differs from that for vertical (Euclide…
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…
