Quantum simulation of chiral phase transitions [PDF]
Journal of High Energy Physics, 2022 Abstract The Nambu–Jona-Lasinio (NJL) model has been widely studied for investigating the chiral phase structure of strongly interacting matter. The study of the thermodynamics of field theories within the framework of Lattice Field Theory is limited by the sign problem, which prevents Monte Carlo evaluation of the functional ...

Chiral pasta: Mixed phases at the chiral phase transition [PDF]
Physical Review D, 2020 Interiors of neutron stars are ultradense and may contain a core of deconfined quark matter. Such a core connects to the outer layers smoothly or through a sharp microscopic interface or through an intermediate macroscopic layer of inhomogeneous mixed ...

Proper time regularization and the QCD chiral phase transition. [PDF]
Sci Rep, 2017 We study the QCD chiral phase transition at finite temperature and finite quark chemical potential within the two flavor Nambu–Jona-Lasinio (NJL) model, where a generalization of the proper-time regularization scheme is motivated and implemented. We find

Effect of the chiral phase transition on axion mass and self-coupling [PDF]
Physical Review D, 2019 We compute the effect of the chiral phase transition of Quantum Chromodynamics on the axion mass and self-coupling; the coupling of the axion to the quarks at finite temperature is described within the Nambu-Jona-Lasinio model.

How tetraquarks can generate a second chiral phase transition [PDF]
, 2016 We consider how tetraquarks can affect the chiral phase transition in theories like QCD, with light quarks coupled to three colors. For two flavors the tetraquark field is an isosinglet, and its effect is minimal.

Deconfinement and chiral restoration phase transition under rotation from holography in an anisotropic gravitational background [PDF]
Physical Review DWe investigate the effects of rotation on deconfinement and chiral phase transitions in the framework of the dynamical holographic QCD model. Instead of transforming to the rotating system by Lorentz boost, we construct an anisotropic gravitational ...

Second-order chiral phase transition in three-flavor quantum chromodynamics? [PDF]
Physical Review D, 2022 We calculate the renormalization group flows of all perturbatively renormalizable interactions in the three-dimensional Ginzburg-Landau potential for the chiral phase transition of three-flavor quantum chromodynamics.

Toward the chiral phase transition in the Roberge-Weiss plane [PDF]
Physical Review D, 2022 We discuss the interplay between chiral and center sector phase transitions that occur in QCD with an imaginary quark chemical potential µ = i (2 n +1) πT/ 3.

On the order of the QCD chiral phase transition for different numbers of quark flavours [PDF]
Journal of High Energy Physics, 2021 The nature of the QCD chiral phase transition in the limit of vanishing quark masses has remained elusive for a long time, since it cannot be simulated directly on the lattice and is strongly cutoff-dependent.
