First-order transition and critical end point in vortex liquids in layered superconductors [PDF]

open access: green, 2001
We calculate various thermodynamic quantities of vortex liquids in a layered superconductor by using the nonperturbative parquet approximation method, which was previously used to study the effect of thermal fluctuations in two-dimensional vortex systems.

Behavior of physical observables in the vicinity of the QCD critical end point [PDF]

open access: green, 2007
Using the SU(3) Nambu-Jona-Lasinio (NJL) model, we study the chiral phase transition at finite $T$ and $\mu_B$. Special attention is given to the QCD critical end point (CEP): the study of physical quantities, as the pressure, the entropy, the baryon ...

QCD critical end point and baryon number fluctuation

open access: yesHe jishu, 2023
One of the main goals of relativistic heavy-ion collision (HIC) is to search for the critical end point (CEP) of quantum chromodynamics (QCD), and distribution of the net-proton number from experimental measurements shows non-monotonic behavior, which ...

Publisher’s Note: Proton-Number Fluctuation as a Signal of the QCD Critical End Point [Phys. Rev. Lett.PRLTAO0031-900791, 102003 (2003)] [PDF]

open access: bronze, 2003
We argue that the event-by-event fluctuation of the proton number is a meaningful and promising observable for the purpose of detecting the QCD critical end-point in heavy-ion collision experiments.

Spectral functions in theσchannel near the critical end point [PDF]

open access: green, 2003
Spectral functions in the $\sigma$-channel are investigated near the chiral critical end point (CEP), that is, the point where the chiral phase transition ceases to be first-ordered in the $(\mu,T)$-plane of the QCD phase diagram.

QCD phase diagram in a finite volume in the PNJL model

open access: yesOpen Physics, 2022
In this work, we study the quantum chromodynamics phase diagram at finite temperature and non-zero chemical potential in the framework of the SU(2) flavor of the Polyakov–Nambu – Jona–Lasinio model (PNJL).

Effects of a Finite Volume in the Phase Structure of QCD

open access: yesUniverse, 2022
Working in the SU(2) flavor version of the NJL model, we study the effect of taking a finite system volume on a strongly interacting system of quarks, and, in particular, the location of the chiral phase transition and the CEP. We consider two shapes for

Finding the critical end point of QCD: lattice and experiment [PDF]

open access: green, 2009
The current status of the search for the critical end point on the lattice and in experiments is discussed. A naive extrapolation is given of lattice results on the location of the critical end point to the continuum limit with the correct pion mass.

Influence of the regularization scheme in the QCD phase diagram in the PNJL model

open access: yesOpen Physics, 2023
In the context of the SU(2) quark flavor version of the Nambu–Jona-Lasinio model extended by the Polyakov loop, the effect of the regularization scheme on the quantum chromodynamics phase structure at finite volume was studied. The way in which the phase
