“…Out of equilibrium, while a comprehensive picture is lacking, universal scaling phenomena have been found in turbulence [2], coarsening [3], ageing [4], or driven-dissipative systems [5]. In recent years, new far-from-equilibrium universality classes for isolated quantum systems have been theoretically identified [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] which have recently started to be probed in cold-atom experiments [24][25][26][27][28]. These universality classes can encompass vastly different theories such as gauge and scalar theories [19,29], or relativistic and non-relativistic theories [12].…”

Many-body quantum systems far from equilibrium can exhibit universal scaling dynamics which defy standard classification schemes. Here, we disentangle the dominant excitations in the universal dynamics of highly-occupied N -component scalar systems using unequal-time correlators. While previous equal-time studies have conjectured the infrared properties to be universal for all N , we clearly identify for the first time two fundamentally different phenomena relevant at different N . We find all N ≥ 3 to be indeed dominated by the same Lorentzian "large-N " peak, whereas N = 1 is characterized instead by a non-Lorentzian peak with different properties, and for N = 2 we see a mixture of two contributions.

The response of chiral fermions to time and space dependent axial imbalance & constant magnetic field is analyzed. The axial-vector-vector-vector three-point function is studied using a real-time approach at finite temperature in the linear response approximation. The chiral magnetic conductivity is given analytically for non-interacting fermions. It is pointed out that local charge conservation plays an important role when the axial imbalance is inhomogeneous. Proper regularization is needed which makes the constant axial imbalance limit delicate: for static chiral charge the CME current vanishes. In the homogeneous (but possible time-dependent) limit of the axial imbalance the CME current is determined solely by the chiral anomaly. As a phenomenological consequence, the observability of the charge asymmetry caused by the CME turns out to be a matter of interplay between various scales of the system. Possible plasma instabilities resulted from the gradient corrections to the CME current are also pointed out.

“…Indeed, an electric current along the magnetic field results in exponentiallygrowing helical field configurations supported by the energy stored in the axial charge, see e.g. [13][14][15][16][17][18][19][20][21][22][23][24][25]. Thus, such a chiral magnetic instability competes with dissipative processes and may considerably affect the lifetime of * lublinm@bgu.ac.il † jdreiten@physics.ucla.edu ‡ andrey.sadofyev@usc.es magnetic fields generated in non-central heavy-ion collisions or contribute to the dynamics of magnetic fields present in the early Universe.…”
