Phase diagram of the three-dimensional NJL model
With the exception of confinement the three-dimensional Nambu−Jona-Lasinio (NJL3) model incorporates many of the essential properties of QCD. We discuss the critical properties of the model at nonzero temperature T and/or nonzero chemical potential μ. We show that the universality class of the thermal transition is that of the d = 2 classical spin model with the same symmetry. We provide eviden...
متن کاملThe Phase Diagram of the Three Dimensional Thirring Model
We present Monte Carlo simulation results for the three dimensional Thirring model on moderate sized lattices using a hybrid molecular dynamics algorithm which permits an odd or non-integer number Nf of fermion flavors. We find a continuous chiral symmetry breaking transition for Nf ≃ 3 with critical exponents consistent with expectations from previous studies. For Nf = 5 the order of the trans...
متن کاملExtended phase diagram of the three-dimensional phase field crystal model.
We determine the phase diagram of the phase field crystal model in three dimensions by using numerical free energy minimization methods. Previously published results, based on single mode approximations, have indicated that in addition to the uniform (liquid) phase, there would be regions of stability of body-centered cubic, hexagonal and stripe phases. We find that in addition to these, there ...
متن کاملThe phase diagram and bulk thermodynamical quantities in the NJL model at finite temperature and density
We reexamine the recent instanton motivated studies of Alford, Rajagopal and Wilczek, and Berges and Rajagopal in the framework of the standard SU(2) Nambu-Jona-Lasinio model. The chiral phase diagram is calculated in the temperature–density plane, and the pressure is evaluated as the function of the density. Obtaining simple approximate relations describing the T-µ and T-p F phase transition l...
متن کاملPhase diagram of the three-dimensional Anderson model of localization with random hopping
Abstract. We examine the localization properties of the three-dimensional (3D) Anderson Hamiltonian with off-diagonal disorder using the transfer-matrix method (TMM) and finitesize scaling (FSS). The nearest-neighbor hopping elements are chosen randomly according to tij ∈ [c− 1/2, c+1/2]. We find that the off-diagonal disorder is not strong enough to localize all states in the spectrum in contr...
