Diquark Condensation in Dense Matter a Lattice Perspective Simon Hands and Susan Morrison

چکیده
We review efforts to study, using the methods of lattice field theory, the phenomenon of diquark condensation via BCS pairing at a Fermi surface, which has been proposed as a mechanism for color superconductivity in dense quark matter. The particular models studied are the Gross-Neveu model and SU(2) lattice gauge theory; in both cases evidence for superfluidity at high density is presented. The behaviour expected for quarks in both fundamental and adjoint representations of SU(2) is contrasted.

MEASURING DIQUARK CONDENSATION IN LATTICE SIMULATIONS OF DENSE MATTER Simon HANDS and Susan MORRISON
We discuss general aspects of the possibility of Bose condensation of diquark pairs in systems of dense matter. Lattice field theory simulations are presented for model four-fermion theories which are expected to manifest the phenomenon, and results from measurements of both diquark two-point and one-point functions presented. Whilst inital results are promising, there remain systematic effects...
متن کاملLattice Simulation of Diquark Condensation in Dense Matter
We present results of a Monte Carlo simulation of a three dimensional Gross-Neveu model with SU(2) ⊗ SU(2) chiral symmetry at non-zero baryon chemical potential µ, corresponding to non-zero baryon density. For µ sufficiently large there is a sharp transition between a phase where the chiral symmetry is broken by a condensate ¯ qq and one where the global U(1) baryon number symmetry appears to b...
متن کاملLattice Approach to Diquark Condensation in Dense Matter
Results are presented of a Monte Carlo simulation of a three dimensional Gross-Neveu model with SU(2) ⊗ SU(2) chiral symmetry at non-zero baryon chemical potential μ, corresponding to non-zero baryon density. The phenomenon of quark pair condensation is sought via measurement of a two point function. For μ sufficiently large there is a sharp transition between a phase where the chiral symmetry ...

We report on a lattice study of two-color QCD with adjoint staggered fermions at high density. We find that the model has no early onset and we report on results for diquark condensation, from simulations with and without a diquark source term.

We study SU(2) lattice gauge theory with two flavors of Wilson fermion at non-zero chemical potential μ and low temperature on a 8 × 16 system. We identify three régimes along the μ-axis. For μ . mπ/2 the system remains in the vacuum phase, and all physical observables considered remain essentially unchanged. The intermediate régime is characterised by a non-zero diquark condensate and an assoc...
