12. Spacetime dynamics of chiral magnetic currents in a hot non-Abelian plasma

Sebastian Grieninger (Stony Brook University)

Talk

The correlations of electric currents in hot non-Abelian plasma are responsible for the experimental manifestations of the chiral magnetic effect in heavy-ion collisions. We evaluate these correlations using holography, and show that they are driven by large-scale topological fluctuations. In a non-Abelian plasma with chiral fermions, local axial charge can be generated either by topological...

18. The effect of electric and chiral magnetic conductivities on azimuthally fluctuating electromagnetic fields and observables in isobar collisions (online)

Irfan Siddique (University of Chinese Academy of Sciences)

23/07/2024 11:30

On-line talk

We study the space-time evolution of electromagnetic fields along
with the azimuthal fluctuations of these fields and their correlation
with the initial matter geometry specified by the participant plane
in the presence of finite electric $\left(\sigma \right)$ and chiral
magnetic $\left({\sigma }_{\chi }\right)$ conductivities in Ru+Ru and
Zr+Zr collisions at $\sqrt{s_{NN}}=200$ GeV. We...

41. Negative magnetoresistence in Dirac Semimetals from Keldysh technique (online)

Ruslan Abramchuk (Ariel University, Israel)

On-line talk

Negative magnetoresistance in topological semimetals is typically considered as a manifestation of chiral magnetic effect (CME). The relation between these two phenomena has the status of hypothesis and is based on the sequence of assumptions. In the present paper we rely on rigorous Keldysh technique of non-equilibrium theory. It allows us to investigate the accumulation of axial charge — the...

62. The weak magnetic effect on the direct photon production and hyperon local spin polarization

Jing-An Sun (Mcgill and Fudan University)

23/07/2024 12:30

Talk

It is expected that there exists an ultra-central strong magnetic field during the early stages of heavy-ion collisions. However, due to the rapid decay, it is a weak magnetic field that along with the evolution of quark-gluon plasma (QGP)

In this work, we study the dissipative correction induced by a weak magnetic field during the QGP stage. Employing the viscous hydrodynamics simulation,...

23. Chiral transport phenomena in core-collapse supernovae

Di-Lun Yang (Institute of Physics, Academia Sinica)

23/07/2024 14:30

Talk

The dynamics of relativistic leptons such as electrons and neutrinos play an important role in the evolution of core-collapse supernovae (CCSN). Nevertheless, chirality as one of the fundamental microscopic properties that could affect lepton transport through the weak interaction has been widely overlooked. In this talk, I will discuss how chiral effects such as the (effective) chiral...

49. Chiral Magnetic and Vortical Effect in the Chiral Kinetic Approach using AMPT model (online)

Zilin yuan (中国科学院大学核科学与技术学院)

23/07/2024 15:00

On-line talk

Built upon the state-of-the-art model a multiphase transport (AMPT), we develop a new module of chiral anomaly transport (CAT) to trace the evolution of the initial topological charge of gauge field created through sphaleron transition at finite temperature and external magnetic field in heavy ion collisions. The eventual experimental signals of chiral magnetic effect(CME) has been measured....

27. Conductivities of CME, CSE and QHE as topological invariants

Prof. Mikhail Zubkov (Ariel University, Israel)

23/07/2024 15:30

Talk

We recent results of our group on quantum Hall effect, Chiral Magnetic effect, and Chiral separation effect. Using Wigner - Weyl calculus the corresponding conductivities are calculated and represented in the form of topological invariants. Effects of interactions, inhomogeneity, and deviations from equilibrium are considered.
