Aspects of the Higgs phase in SU(2)xU(1) lattice gauge Higgs theory
Shivam Gangwani, Jeff Greensite, Anass Oualla
Using a simplified lattice version of the electroweak sector of the standard model, with dynamical fermions excluded, we determine at fixed Weinberg angle the transition line betwe…
Separation-of-charge confinement and the Higgs transition in SU(3) gauge Higgs theory
Jeff Greensite, Hou Y. Yau
With SU(3) gauge Higgs theory as an example, we examine critically the idea that the confinement property in an SU(N) gauge-Higgs theory, with the Higgs field in the fundamental re…
Hartree-Fock with Nambu spinors, and d-wave condensation in the 2D Hubbard model
Kazue Matsuyama, Jeff Greensite
The usual Hartree-Fock approximation to the Hubbard model is based on eigenstates of the electron number operator. But this formulation is not unique. A different (and inequivalent…
Quantum excitations of static charges in the Ginzburg-Landau model of superconductivity
Jeff Greensite, Kazue Matsuyama
We point out that in superconductors there may exist localized quantum excitations of the electric and condensate fields surrounding a static charge, which cannot be interpreted as…
Multiplicity, localization, and domains in the Hartree-Fock ground state of the two-dimensional Hubbard model
Kazue Matsuyama, Jeff Greensite
We explore certain properties of the Hartree-Fock approximation to the ground state of the two-dimensional Hubbard model, emphasizing the fact that in the Hartree approach there is…
Symmetry, Confinement, and the Higgs Phase
Jeff Greensite, Kazue Matsuyama
We show that the Higgs and confinement phases of a gauge Higgs theory, with the Higgs field in the fundamental representation of the gauge group, are distinguished both by a broken…
