Cold, dense matter via the lattice NJL model
David N. Walters
We simulate the lattice Nambu--Jona-Lasinio (NJL) model in 3+1-dimensions at non-zero baryon chemical potential (mu) and zero temperature (T) and treat the results as phenomenologi…
The Lattice NJL Model at Non-zero Baryon and Isospin Densities
David N. Walters, Simon Hands
We present initial results of a numerical investigation of the chiral symmetry restoring transition in the (3+1)-dimensional Nambu -- Jona-Lasinio model with both non-zero baryon c…
Numerical Portrait of a Relativistic BCS Gapped Superfluid
Simon Hands, David N. Walters
We present results of numerical simulations of the 3+1 dimensional Nambu - Jona-Lasinio (NJL) model with a non-zero baryon density enforced via the introduction of a chemical poten…
A BCS Gapped Superfluid on the Lattice
David N. Walters
We discuss results of numerical analyses of the 3+1 dimensional Nambu--Jona-Lasinio model at non-zero baryon density. By studying relevant order parameters, it is shown that the mo…
A BCS Gap on the Lattice
David N. Walters, Simon Hands
Monte Carlo simulations of the 3+1 dimensional NJL model are performed with baryon chemical potential mu>0. For mu>Sigma_0, the constituent quark mass in vacuum, chiral symmetry is…
