Applying Complex Langevin Simulations to Lattice QCD at Finite Density
J. B. Kogut, D. K. Sinclair
We study the use of the complex-Langevin equation (CLE) to simulate lattice QCD at a finite chemical potential () for quark-number, which has a complex fermion determinant that…

D. K. Sinclair, J. B. Kogut
We simulate lattice QCD at finite quark-number chemical potential, , using the complex-Langevin equation (CLE) with gauge-cooling and adaptive updating to prevent instabilities.…
Complex Langevin Simulations of QCD at Finite Density -- Progress Report
D. K. Sinclair, J. B. Kogut
We simulate lattice QCD at finite quark-number chemical potential to study nuclear matter, using the complex Langevin equation (CLE). The CLE is used because the fermion determinan…
The chiral phase transition for lattice QCD with 2 colour-sextet quarks
J. B. Kogut, D. K. Sinclair
QCD with 2 flavours of massless colour-sextet quarks is studied as a possible walking-Technicolor candidate. We simulate the lattice version of this model at finite temperatures ne…
Thermodynamics of lattice QCD with 3 flavours of colour-sextet quarks II: N_t=6 and N_t=8
J. B. Kogut, D. K. Sinclair
We have been studying QCD with 2 flavours of colour-sextet quarks as a candidate walking-Technicolor theory using lattice-QCD simulations. The evolution of the coupling constant wi…

D. K. Sinclair, J. B. Kogut
We continue our simulations of QCD with 2 flavours of colour-sextet quarks as a model for walking technicolor. QCD with 3 flavours of colour-sextet quarks is also studied for compa…
Emerging understanding of the ΔI = 1/2 Rule from Lattice QCD
P. A. Boyle, N. H. Christ, N. Garron +8
There has been much speculation as to the origin of the ΔI = 1/2 rule (Re A_0/Re A_2 \simeq 22.5). We find that the two dominant contributions to the ΔI=3/2, K \to ππ correlation f…
Thermodynamics of lattice QCD with 3 flavours of colour-sextet quarks
J. B. Kogut, D. K. Sinclair
We have been studying QCD with 2 flavours of colour-sextet quarks to distinguish whether it is QCD-like or conformal. For comparison we are now studying QCD with 3 flavours of colo…
Thermodynamics of lattice QCD with 2 sextet quarks on N_t=8 lattices
J. B. Kogut, D. K. Sinclair
We continue our lattice simulations of QCD with 2 flavours of colour-sextet quarks as a model for conformal or walking technicolor. A 2-loop perturbative calculation of the -fun…
Magnetic monopole plasma phase in (2+1)d compact quantum electrodynamics with fermionic matter
Wesley Armour, Simon Hands, John B. Kogut +3
We present the first evidence from lattice simulations that the magnetic monopoles in three dimensional compact quantum electrodynamics (cQED3) with N_f=2 and N_f= 4 four-component…

Wesley Armour, John B. Kogut, Costas Strouthos
We present results from the first lattice simulations of three dimensional non-compact quantum electrodynamics (QED3) with N_f four-component fermion flavors coupled to a weak Z(2)…
Lattice Gauge Theory and (Quasi)-Conformal Technicolor
D. K. Sinclair, J. B. Kogut
QCD with 2 flavours of massless colour-sextet quarks is studied as a theory which might exhibit a range of scales over which the running coupling constant evolves very slowly (walk…
Lattice QCD at finite temperature and density in the phase-quenched approximation
J. B. Kogut, D. K. Sinclair
QCD at a finite quark-number chemical potential has a complex fermion determinant, which precludes its study by standard lattice QCD simulations. We therefore simulate lattice…

J. B. Kogut, D. K. Sinclair
The Rational Hybrid Monte Carlo (RHMC) algorithm extends the Hybrid Monte Carlo algorithm for lattice QCD simulations to situations involving fractional powers of the determinant o…

J. B. Kogut, D. K. Sinclair
We simulate lattice QCD with 2 flavours of massless quarks on lattices of temporal extent N_t=8, to study the finite temperature transition from hadronic matter to a quark-gluon pl…
Quantization and simulation of Born-Infeld non-linear electrodynamics on a lattice
J. B. Kogut, D. K. Sinclair
Born-Infeld non-linear electrodynamics arises naturally as a field theory description of the dynamics of strings and branes. Most analyses of this theory have been limited to study…
Lattice simulations of Born-Infeld non-linear QED
D. K. Sinclair, J. B. Kogut
Born-Infeld non-linear electrodynamics was introduced to render the self energy of a point particle finite. It has recently been revived as a field theory for branes and strings. W…
The Relationship of the Laplacian Gauge to the Landau Gauge
Jeffrey E. Mandula
The Laplacian gauge for gauge group SU(N) is discussed in perturbation theory. It is shown that to the lowest non-trivial order, O(g^1), configurations in the Laplacian gauge autom…

We discuss the current state of what is known non-perturbatively about the gluon propagator in QCD, with emphasis on the information coming from lattice simulations. We review the…
Gauge Fixing and the Gibbs Phenomenon
Jeffrey E. Mandula
We address the question of why global gauge fixing, specifically to the lattice Landau gauge, becomes an extremely lengthy process for large lattices. We construct an artificial "g…
