摘要

Relativistic Navier-Stokes equations express the conservation of the energy-momentum tensor and the particle number current in terms of the local hydrodynamic variables: temperature, fluid velocity, and the chemical potential. We show that the viscous-fluid equations are stable and causal if one adopts suitable non-equilibrium definitions of the hydrodynamic variables.

1-loop matching of a thermal Lorentz force

M. Laine

Summary: The study of the diffusion and kinetic equilibration of heavy quarks within a hot QCD medium benefits from understanding the coloured Lorentz force acting on them. By determining 1-loop matching coefficients for the electric and magnetic parts of a Lorentz force, it enables a lattice study of a color-magnetic 2-point correlator.

Spin relaxation rate for heavy quarks in weakly coupled QCD plasma

Masaru Hongo, Xu-Guang Huang, Matthias Kaminski, Mikhail Stephanov, Ho-Ung Yee

Summary: We calculate the relaxation rate of the spin density of heavy quarks in a perturbative QCD plasma and demonstrate the differences between three different methods of calculation, while finding that the relaxation rate of the spin is smaller than that of other non-hydrodynamic modes in the heavy-quark limit.

Non-conformal attractor in boost-invariant plasmas

Chandrodoy Chattopadhyay, Sunil Jaiswal, Lipei Du, Ulrich Heinz, Subrata Pal

Summary: This study investigates the dissipative evolution of (0+1)-dimensionally expanding media with Bjorken symmetry by considering the non-zero bulk viscous pressure induced by mass. It is found that even a small mass can significantly modify the attractor for the shear Reynolds number, with shear and bulk viscous pressures not relaxing quickly to a non-equilibrium state. The longitudinal pressure, however, continues to approach a far-off-equilibrium attractor early on, driven by rapid longitudinal expansion.

Second order chiral kinetic theory under gravity and antiparallel charge-energy flow

Tomoya Hayata, Yoshimasa Hidaka, Kazuya Mameda

Summary: In this study, we derived the chiral kinetic theory under the presence of gravitational Riemann curvature and discovered new types of fermionic transport phenomena, including charge current and energy-momentum tensor induced by the curvature. It was found that inhomogeneous fluid vorticity can induce charge and energy currents in opposite directions, due to the spin-curvature coupling. Additionally, possible applications to Weyl/Dirac semimetals and heavy-ion collision experiments were briefly discussed.

Gravitational susceptibility of QGP

Alex Buchel

Summary: In this study, we use N = 2* and cascading gauge theory holographic models to investigate the gravitational susceptibility of strongly coupled nonconformal quark-gluon plasma. We find that in theories with a relevant coupling constant, the gravitational susceptibility depends on the renormalization scheme. To overcome this issue, we propose using the temperature derivative of the susceptibility, d kappa/dlnT, as a scheme-independent characteristic of quark-gluon plasma. Furthermore, we show that the critical behavior of kappa can vary significantly near seemingly identical thermal phase transitions.

Color screening in quantum chromodynamics

Alexei Bazavov, Johannes Heinrich Weber

Summary: This article reviews lattice studies of color screening in the quark-gluon plasma, discussing the onset and significance of color screening in the QCD transition region. It clarifies to what extent the weak-coupling picture captures key properties of color screening at different temperatures. The study also delves into different regimes pertaining to color screening and thermal dissociation of static quarks for various spatial correlation functions studied on the lattice.

Critical behaviour of hydrodynamic series

M. Asadi, H. Soltanpanahi, F. Taghinavaz

Summary: The study investigates the time-dependent perturbations of strongly coupled N = 4 SYM theory at finite temperature and finite chemical potential with a second order phase transition. The theory is modelled by a top-down Einstein-Maxwell-dilaton description and focuses on spin-1 and spin-2 sectors of perturbations, calculating hydrodynamic transport coefficients up to the third order in gradient expansion. Analytically, it is found that all hydrodynamic quantities share the same critical exponent near the critical point theta = 12, and a relationship between symmetry enhancement of the underlying theory and the vanishing of the third order hydrodynamic transport coefficient is proposed.

Gliding Down the QCD Transition Line, from Nf=2 till the Onset of Conformality

Andrey Yu Kotov, Maria Paola Lombardo, Anton Trunin

Summary: The study focuses on the hot QCD transition with varying number of flavours, exploring different universality classes and the transition from scaling window to mean field behavior. It summarizes the properties of the transition process, including first order transitions, cosmological applications, and the essential singularity at the onset of the conformal window predicted by the functional renormalisation group.

Chiral transport in curved spacetime via holography

Alexander Avdoshkin, Rustem Sharipov

Summary: In this holographic model, the parity-odd responses of a strongly interacting plasma to external electromagnetic and gravitational fields at finite temperature and chemical potential were computed. Not only were the chiral magnetic and vortical effects reproduced, but gradient corrections to these effects due to the gravitational anomaly were also obtained. Moreover, the energy-momentum and current responses to the gravitational field were found to be similarly determined by the gravitational anomaly.

Efficient numerical integration of thermal interaction rates

G. Jackson, M. Laine

Summary: This passage discusses an algorithm to represent, regularize, and evaluate a class of thermal 2 <-> 2 and 1 <-> 3 interaction rates, including automated inclusion of virtual corrections to 1 <-> 2 scatterings. The algorithm eliminates logarithmic and double-logarithmic IR divergences from the real 2 <-> 2 and 1 <-> 3 processes, and also reviews thermal and chemical potential induced contributions that require resummation for ultrarelativistic plasma particles.

Disentangling quark and gluon jets with normalizing flows

Matthew J. Dolan, Ayodele Ore

Summary: The study introduces TopicFlow, a method based on normalizing flows, to learn quark and gluon jet topic distributions from mixed datasets obtained from experiments. The method proves to be efficient in high dimensions and can improve calibration accuracy of a classifier. The flow likelihoods can also be utilized for outlier-robust quark/gluon classification.

Effective holographic models for QCD: Thermodynamics and viscosity coefficients

Alfonso Ballon-Bayona, Luis A. H. Mamani, Alex S. Miranda, Vilson T. Zanchin

Summary: This work investigates a finite-temperature extension of the effective holographic models for QCD (EHQCD), finding black hole solutions categorized into large and small black holes at temperatures above a certain temperature T-min. Thermodynamic quantities and viscosity coefficients are shown to be sensitive to model parameters, with the bulk viscosity ratio zeta/s displaying rapid growth near T-min. Comparison with lattice SU(N-C) results and JETSCAPE Collaboration results on heavy ion collisions show compatibility with appropriate fixes of the coupling as a function of the conformal dimension.

Entropy production far from equilibrium in a chiral charged plasma in the presence of external electromagnetic fields

Casey Cartwright

Summary: This study reports on the time evolution of a charged N = 4 SYM plasma with an axial anomaly under strong electromagnetic fields, exploring the changes in axial current and axial charges. The study also shows that after a sufficiently long time, both the entropy and holographic entanglement entropy of a strip-like topology will grow linearly with time.

Hydrodynamic effective field theory and the analyticity of hydrostatic correlators

Akash Jain, Pavel Kovtun, Adam Ritz, Ashish Shukla

Summary: The study focuses on one-loop corrections to the retarded and symmetric hydrostatic correlation functions in relativistic hydrodynamics, specifically looking at charge diffusion. By considering diffusive charge density fluctuations and augmenting it with momentum fluctuations, the study shows that loop corrections maintain the analyticity of retarded correlation functions in spatial momentum, as a result of the KMS constraint and thermal screening effects. The interacting field theory for diffusive hydrodynamics is developed to analyze this phenomenon, viewing it as a limit of relativistic hydrodynamics without temperature and longitudinal velocity fluctuations.
