BCS states and D-wave condensates in the 2D Hubbard model
Kazue Matsuyama, Jeff Greensite
We consider states of BCS form in the 2D Hubbard model which, starting from some arbitrary point in state space in the neighborhood of a Hartree-Fock ground state, are relaxed with…
A Variational Improvement of the Hartree-Fock Approach to the 2D Hubbard Model
Kazue Matsuyama, Jeff Greensite
We consider a refinement of the usual Hartree-Fock method applied to the 2D Hubbard model, in Nambu spinor formulation. The new element is the addition of a "condensate inducing" t…
Effective Polyakov line action from the relative weights method
J. Greensite, K. Langfeld
We apply the relative weights method (arXiv:1209.5697) to determine the effective Polyakov line action for SU(2) lattice gauge theory in the confined phase, at lattice coupling bet…
Measurements of the Yang-Mills vacuum wavefunctional, and related studies
J. Greensite
I present numerical tests of several recent proposals for the Yang-Mills vacuum wavefunctional in D=2+1 dimensions. In these tests the predicted relative values of the squared wave…
k-String tensions and their large-N dependence
J. Greensite, B. Lucini, A. Patella
We consider whether the 1/N corrections to k-string tensions must begin at order 1/N^2, as in the Sine Law, or whether odd powers of 1/N, as in Casimir Scaling, are also acceptable…
Coulomb Confinement from the Yang-Mills Vacuum State in 2+1 Dimensions
J. Greensite, S. Olejnik
The Coulomb-gauge ghost propagator, and the color-Coulomb potential, are computed in an ensemble of configurations derived from our recently proposed Yang-Mills vacuum wavefunction…
