26. Chiral Kinetic Theory in Curved Space Revisited and Radiative Corrections (online)

Shu Lin (Sun Yat-sen University)

On-line talk

It is usually believed that physics in off-equilibrium state can be equivalently studied using equilibrium state with suitable metric perturbation. We point out it is not the case for spin polarization phenomena: the exisiting chiral kinetic theory in curved space fails to recover all the couplings between spin and hydrodynamic gradients [1]. We present a new form of chiral kinetic theory in...

80. Baryon Stopping and Initial Angular Momentum in Heavy Ion Collisions (online)

On-line talk

Non-central heavy-ion collisions contain large orbital angular momentum ($\sim {10}^{3\sim 6}\hslash$) that, at high energies, is expected to induce strong vorticity in the hot bulk fluid and generate global spin polarization of produced particles. As the collision energy $\sqrt{s}$ approaches threshold, the observed global spin polarization should reach a maximum, then drop to zero as...

58. Gauge invariance and thermodynamic stability of rotating magnetized systems

Talk

In this presentation, I revisit the Dirac theory under an external magnetic field and rotation. Motivated by experimental observations of significant vorticities in heavy ion collisions, there has been active exploration into the thermodynamics of rotating QCD matter. While the pure rotational effect has received attention, the interplay between rotation and magnetic fields remains...

25. Effective Lagrangian for the macroscopic motion of fermionic matter

Talk

We consider macroscopic motion of quantum field systems. The Zubarev statistical operator allows us to describe several types of motion of such systems in thermal equilibrium. We formulate the corresponding effective theory on the language of a functional integral. The effective Lagrangian is calculated explicitly for the fermionic systems interacting with dynamical gauge fields. Possible...

45. Electromagnetic field induction in quark-gluon plasma due to thermoelectric effects (online)

On-line talk

Quark-gluon plasma (QGP) produced in relativistic heavy-ion collisions cools rapidly as the medium evolves. QGP with non-zero conserved charged current, higher thermal conductivity of medium advances in global thermalization. Being made of electrically charged partons, heat current leads to electromagnetic (EM) field induction in the medium, commonly known as the thermoelectric effect....

19. Magnetic catalysis and diamagnetism from pion fluctuations (online)

Jie Mei (中国科学院大学物理科学学院)

25/07/2024 12:30

On-line talk

In the framework of Nambu--Jona-Lasinio model beyond mean field approximation, the effects of pion fluctuations on (inverse) magnetic catalysis and magnetic susceptibility are studied. The negative magnetic susceptibility at low temperature is observed when contributions from both neutral and charged pions are taken into account. In weak field approximation, it is observed that at finite...

16. Charge transport in strongly magnetized relativistic matter

Prof. Igor Shovkovy (Arizona State University)

Talk

Using the imaginary part of the self-energy function in the Landau-level representation, we derive the fermion damping rate in a hot magnetized plasma at the leading order of coupling. The results are used to investigate the longitudinal and transverse electrical conductivities. In the relativistic regime, these conductivities exhibit a scaling behavior expressed in terms of dimensionless...

67. Influence of magnetic field-induced anisotropic gluon pressure during pre-equilibrium (online)

Ana Mizher (IFT-UNESP)

25/07/2024 17:00

On-line talk

Magnetic fields of a large intensity can be generated in peripheral high-energy heavy-ion collisions. Although the intensity drops down fast and, moreover, it is not clear whether the fields last long enough to induce a magnetization during the quark-gluon plasma phase, most of the models and simulations predict a significant intensity that lasts up to proper times of order 1 fm after the...

60. Search for the Chiral Magnetic Effect by Event Shape Engineering Differentially in Invariant Mass in Au+Au Collisions at $\sqrt{s_{NN}}$ = 200 GeV from STAR

Chiral Magnetic Effect (CME) is a phenomenon in which electric charge is separated by a strong magnetic field from local domains of chirality imbalance and parity violation in quantum chromodynamics (QCD). The CME-sensitive observable, charge-dependent three-particle azimuthal correlator $\mathrm{\Delta }\gamma$, is contaminated by a major physics background proportional to the particle elliptic...
