“…As noted in the discussion of figure 7, the first peak in the response is clearly associated with the propagation of the leading edge of the anisotropy pulse -the region of near-maximal slope on the side of the pulse closest to the boundary. Therefore, for pulses of non-negligible width σ centered at some depth r 0 , one should expect that the time of 27 Specifically, εL in the magnetic case.…”

“…Similarly, it is clear that large, but transient, electromagnetic fields are generated in heavy ion collisions. A growing body of work [24][25][26][27][28] suggests that electromagnetic effects may play a significant role despite the small value of the fine structure constant. Electromagnetic effects on equilibrium QCD properties are also under study using lattice gauge theory [29][30][31][32].…”

Using holography, we study the evolution of a spatially homogeneous, far from equilibrium, strongly coupled N = 4 supersymmetric Yang-Mills plasma with a non-zero charge density or a background magnetic field. This gauge theory problem corresponds, in the dual gravity description, to an initial value problem in Einstein-Maxwell theory with homogeneous but anisotropic initial conditions. We explore the dependence of the equilibration process on different aspects of the initial departure from equilibrium and, while controlling for these dependencies, examine how the equilibration dynamics are affected by the presence of a non-vanishing charge density or an external magnetic field. The equilibration dynamics are remarkably insensitive to the addition of even large chemical potentials or magnetic fields; the equilibration time is set primarily by the form of the initial departure from equilibrium. For initial deviations from equilibrium which are well localized in scale, we formulate a simple model for equilibration times which agrees quite well with our results.

“…The time evolution of n 5 in case of massive particles in the background with constant and homogeneous fields has been derived for the first time by Warringa in [48], where he has shown it can be directly obtained from the Schwinger production rate for the case of E B, namely [58][59][60][61][62] …”

In this article we study spontaneous chiral symmetry breaking for quark matter in the background of static and homogeneous parallel electric field E and magnetic field B. We use a Nambu-JonaLasinio model with a local kernel interaction to compute the relevant quantities to describe chiral symmetry breaking at finite temperature for a wide range of E and B. We study the effect of this background on inverse catalysis of chiral symmetry breaking for E and B of the same order of magnitude. We then focus on the effect of equilibration of chiral density, n5, produced dynamically by axial anomaly on the critical temperature. The equilibration of n5, a consequence of chirality flipping processes in the thermal bath, allows for the introduction of the chiral chemical potential, µ5, which is computed self-consistently as a function of temperature and field strength by coupling the number equation to the gap equation, and solving the two within an expansion in E/T 2 , B/T 2 and µ 2 5 /T 2 . We find that even if chirality is produced and equilibrates within a relaxation time τM , it does not change drastically the thermodynamics, with particular reference to the inverse catalysis induced by the external fields, as long as the average µ5 at equilibrium is not too large.

“…-The CME is the generation of vector current by external magnetic field in chirality-imbalanced (P-odd) medium. Historically, the CME has been studied through different theoretical approaches in a number of contexts ranging from astrophysics [102], condensed matter systems [103][104][105][106][107][108][109][110][111], QCD physics [2,15,[112][113][114][115][116][117][118][119][120][121] , to holographic models [122][123][124][125][126][127][128][129][130][131][132][133][134]. The recent reviews of CME are [27,29,30,135].…”

Electromagnetic fields and anomalous transports in heavy-ion collisions—a pedagogical review

2016

View full text Add to dashboard Cite

The hot and dense matter generated in heavy-ion collisions may contain domains which are not invariant under P and CP transformations. Moreover, heavy-ion collisions can generate extremely strong magnetic fields as well as electric fields. The interplay between the electromagnetic field and triangle anomaly leads to a number of macroscopic quantum phenomena in these P-and CP-odd domains known as the anomalous transports. The purpose of the article is to give a pedagogical review of various properties of the electromagnetic fields, the anomalous transports phenomena, and their experimental signatures in heavyion collisions.
