The chiral magnetic wave from the interplay between the chiral magnetic effect and the chiral separation effect is simulated in a box system with the periodic boundary condition based on the chiral kinetic equations of motion. Simulation results are compared with available limits from theoretical derivations, and effects of the temperature, the magnetic field, and the specific shear viscosity on the key properties of the chiral magnetic wave are discussed. Our study serves as a baseline for further simulations of chiral anomalies in relativistic heavy-ion collisions.

Built upon the state-of-the-art model a multiphase transport, we develop a new module of chiral anomaly transport (CAT) to trace the evolution of the initial topological charge of the gauge field created through sphaleron transition at finite temperature and the external magnetic field in heavy-ion collisions. The eventual experimental signals of the chiral magnetic effect (CME) have been measured. The CAT explicitly shows the generation and evolution of the charge separation, the signals of the CME through the CAT are quantitatively in agreement with the experimental measurements in $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{s}=200$ GeV, and the centrality dependence of the CME fraction follows that of the fireball temperature. Our simulation supports the generation of the CME.

To incorporate the effect of gluons on the evolution dynamics of the quark matter produced in relativistic heavy-ion collisions, we extend the three-flavor Nambu–Jona-Lasinio (NJL) transport model to include the contribution from the Polyakov loops. Imbedding the resulting pNJL partonic transport model in an extended multiphase transport (extended AMPT) model, we then study the elliptic flow splittings between particles and their antiparticles in relativistic heavy-ion collisions at beam energy scan energies. We find that a weak quark vector interaction in the partonic phase is able to describe the elliptic flow splitting between protons and antiprotons in heavy-ion collisions at $\sqrt{s_{NN}}=7.7$ to 39 GeV. Knowledge of the quark vector interaction is useful for understanding the equation of state of quark matter at large baryon chemical potentials and thus the location of the critical point in the QCD phase diagram.

We investigate the signal of the chiral magnetic effect (CME) in Au + Au collisions and isobar collisions of Ru 44 96 + Ru 44 96 and Zr 40 96 + Zr 40 96 in the newly developed chiral anomaly transport module based on the state-of-the-art model “a multiphase transport.” Our numerical simulation results for the ratio charge correlation Δ γ in Ru + Ru and Zr + Zr collisions are close to the latest experimental data. The simulation shows that the CME signal is larger in Ru + Ru collisions than that in Zr + Zr collisions, while the background is smaller, and the upper limit of the CME signal is 15 % in the isobar collisions.
