A Bcs Condensate in Njl 3+1 ?

چکیده
We present results from a lattice Monte Carlo study of the Nambu – Jona-Lasinio model in 3+1 dimensions with a baryon chemical potential μ 6= 0. As μ is increased there is a transition from a chirally-broken phase to relativistic quark matter, in which baryon number symmetry appears spontaneously broken by a diquark condensate at the Fermi surface, implying a superfluid ground state. Finite volume corrections to this relativistic BCS scenario, however, are anomalously large.

We present preliminary evidence of BCS diquark condensation in the 3 + 1 dimensional Nambu–Jona-Lasinio (NJL) model at non-zero chemical potential (μ) on the lattice. Large N results are used to match the model’s parameters to low energy, zero density phenomenology. A diquark source j is added in a partially quenched approximation to enable the measurement of lattice diquark observables. In par...
متن کاملEvidence for BCS Diquark Condensation in the 3 + 1 d Lattice NJL Model
Abstract: We present results of numerical simulations of the 3+1d Nambu – JonaLasinio model with a non-zero baryon chemical potential μ, with particular emphasis on the superfluid diquark condensate and associated susceptibilities. The results, when extrapolated to the zero diquark source limit, are consistent with the existence of a non-zero BCS condensate at high baryon density. The nature of...
متن کاملPossible crossover from BCS superconductivity to Bose-Einstein condensate in quark matter
The possibility of the crossover from the BCS pairing to the Bose-Einstein condensate (BEC) of diquarks with going down in density is discussed in the framework of in the Nambu Jona-Lasinio (NJL) model. We find that the quark matter at moderate density may be close to the intermediate of the crossover, the precursory regime to the BEC phase.
متن کاملA BCS Gap on the Lattice
Monte Carlo simulations of the 3+1 dimensional NJL model are performed with baryon chemical potential μ > 0. For μ ∼ Σ0, the constituent quark mass in vacuum, chiral symmetry is restored and a diquark condensate 〈qq+〉 forms. We analyse the fermion propagator and find evidence for particle-hole mixing in the vicinity of the Fermi surface and an energy gap ∆ > 0, both of which provide evidence fo...

We give an introduction to the dynamical symmetry breaking with large anomalous dimension. This is the basis of tightly bound composite Higgs models such as walking technicolor, strong ETC technicolor and top quark condensate, which are all characterized by the large anomalous dimension, γm ≃ 1 (walking technicolor), 1 < γm < 2 (strong ETC technicolor) and γm ≃ 2 (top quark condensate) due to n...
