Ferroelectric Nematic-Isotropic Liquid Critical End Point. [PDF]
Physical Review Letters, 2023 A critical end point above which an isotropic phase continuously evolves into a polar (ferroelectric) nematic phase with an increasing electric field is found in a ferroelectric nematic liquid crystalline material. The critical end point is approximately

Thermal Critical Points and Quantum Critical End Point in the Frustrated Bilayer Heisenberg Antiferromagnet. [PDF]
Physical Review Letters, 2018 We consider the finite-temperature phase diagram of the S=1/2 frustrated Heisenberg bilayer. Although this two-dimensional system may show magnetic order only at zero temperature, we demonstrate the presence of a line of finite-temperature critical ...

Criticality of QCD in a holographic QCD model with critical end point [PDF]
Chinese Physics C, 2018 The thermodynamics of strongly interacting matter near the critical end point are investigated in a holographic QCD model, which can describe the QCD phase diagram in \begin{document}$ T-\mu $\end{document} plane qualitatively.

On the critical end point in a two-flavor linear sigma model coupled to quarks [PDF]
European Physical Journal A, 2019 We use the linear sigma model coupled to quarks to explore the location of the phase transition lines in the QCD phase diagram from the point of view of chiral symmetry restoration at high temperature and baryon chemical potential.

The Effect of Charge, Isospin, and Strangeness in the QCD Phase Diagram Critical End Point [PDF]
Universe, 2021 In this work, we discuss the deconfinement phase transition to quark matter in hot/dense matter. We examine the effect that different charge fractions, isospin fractions, net strangeness, and chemical equilibrium with respect to leptons have on the ...

The entanglement properties of holographic QCD model with a critical end point [PDF]
Chinese Physics C, High Energy Physics & Nuclear Physics, 2020 We investigated different entanglement properties of a holographic QCD (hQCD) model with a critical end point at the finite baryon density. Firstly, we considered the holographic entanglement entropy (HEE) of this hQCD model in a spherical shaped region ...

Fluctuating temperature and baryon chemical potential in heavy-ion collisions and the position of the critical end point in the effective QCD phase diagram [PDF]
Physical Review D, 2020 We use the linear sigma model with quarks to locate the critical end point in the effective QCD phase diagram accounting for fluctuations in temperature and quark chemical potential.

New approach to lattice QCD at finite density; results for the critical end point on coarse lattices [PDF]
Journal of High Energy Physics, 2020 All approaches currently used to study finite baryon density lattice QCD suffer from uncontrolled systematic uncertainties in addition to the well-known sign problem. We formulate and test an algorithm, sign reweighting, that works directly at finite μ =

Locating the QCD critical end point through peaked baryon number susceptibilities along the freeze-out line [PDF]
, 2017 We investigate the baryon number susceptibilities up to fourth order along different freeze-out lines in a holographic QCD model with a critical end point (CEP), and we propose that the peaked baryon number susceptibilities along the freeze-out line can ...

QCD critical end point from a realistic PNJL model [PDF]
, 2018 With parameters fixed by critical temperature and equation of state at zero baryon chemical potential, a realistic Polyakov--Nambu--Jona-Lasinio (rPNJL) model predicts a critical end point of chiral phase transition at $(\mu_B^E= 720 {\rm MeV}, T^E=93 ...
