“…where we have written the result in terms of the trace of the charge matrix Q. This expression agrees with the results found in [58] for the baryon and isospin number densities of a hadronic fluid under rotation [59], which shows the existence of a vorticity coupling with the pion gradient in the absence of chiral imbalance. It is nevertheless surprising that no such effect survives in the spatial currents themselves, as it is seen from our explicit results.…”

The anomalous currents of two-flavor chiral nuclear matter in the presence of chiral imbalance are computed, using recently developed methods exploiting generalized transgression, which facilitates the evaluation of both the equilibrium partition function and the covariant currents. The constitutive relations for both the broken and unbroken phase of the theory are studied and the out-of-equilibrium nondissipative transport coefficients determined. In the superfluid phase, the vector covariant currents exhibit nondissipative chiral electric, magnetic, and vortical effects, the latter governed by chiral imbalance.

“…to consider a rotating plasma in a constant magnetic field. As it is shown in [35], the Dirac equation, in this case, has an analytical solution, that can be used to determine the corresponding Wigner function. The latter can then be used to determine the proper time dependence of the temperature and other thermodynamic quantities by carrying out the method presented in this paper.…”

“…The solutions presented in (II.34), (II. 35), and (II.36) for vanishing magnetic fields are denoted by "Bjorken", "Hubble at r = 0" and "Gubser at r = 0", respectively. The results corresponding to the solution of the energy equation with point to point varying magnetic fields are denoted by δB HI and δB LI in the high-and low-temperature approximations.…”

By combining the Wigner function formalism of relativistic quantum kinetic theory with fundamental equations of relativistic magnetohydrodynamics (MHD), we present a novel approach to determine the proper time evolution of the temperature and other thermodynamic quantities in a uniformly expanding hot, magnetized, and weakly interacting plasma. The aim is to study the contribution of quantum corrections to this evolution. We first determine the corresponding Wigner function in terms of the solution of the Dirac equation in the presence of a constant magnetic field. Using this function, we then compute the energy-momentum tensor of the above-mentioned plasma, which eventually yields its energy density and pressure. Plugging these quantities in the energy equation of relativistic MHD, we arrive, after choosing an appropriate coordinate system, at a differential equation for the temperature as a function of the proper time. The numerical solution of this equation leads finally to the proper time evolution of the temperature. The latter is then used to determine the evolution of a large number of thermodynamic quantities in this expanding and magnetized plasma. We compare our results with other existing results from relativistic MHD. We also comment on the effect of point to point decaying magnetic fields on the thermodynamic properties of this plasma.

“…Simulations suggest that the produced magnetic field is on order of 10 18 −10 20 Gauss and linearly proportional to the collision energy [3][4][5][6]. The estimated magnetic characteristic length [7], i.e. 1/ √ eB 1 , at its peak is comparable to the typical length scale of strong interactions at low energies, namely 1/Λ QCD .…”

Generalization of Bantilan-Ishi-Romatschke flow to magnetohydrodynamics

We present a generalization of the Bantilan-Ishi-Romatschke (BIR) solution of relativistic hydrodynamics to relativistic magnetohydrodynamics (RMHD). Using the symmetries of the boundary of the Kerr-AdS5 black hole, and certain simplifying assumptions we solve the equations of RMHD on this boundary for a highly conductive fluid. We then transform the resulting solution to the flat spacetime. Furthermore, we show that the force-free condition causes the magnetic field to become singular at particular points and propose a regularization process for removing the singularities. The regularization process reveals the importance of non-vanishing electrical current in RMHD.
