“…Recently, the dispersion spectra of a gluon in a hot QCD medium in the presence of a strong as well as a weak magnetic field limit is studied [38]. The effect of the strong magnetic field on the collisional energy loss of heavy quark moving in a magnetized thermal partonic medium has been studied [39]. Also the anisotropic momentum diffusion and the drag coefficients of heavy quarks have been computed in a strongly magnetized quark-gluon plasma beyond the static limit within the framework of Langevin dynamics [40].…”

We examined the effects of the weak magnetic field on the properties of heavy quarkonia immersed in a thermal medium of quarks and gluons and studied how the magnetic field affects the quasifree dissociation of quarkonia in the aforementioned medium. For that purpose, we have revisited the general structure of gluon self-energy tensor in the presence of a weak magnetic field in thermal medium and obtained the relevant structure functions using the imaginary-time formalism. The structure functions give rise to the real and imaginary parts of the resummed gluon propagator, which further give the real and imaginary parts of the dielectric permittivity. The real and imaginary parts of the dielectric permittivity will be used to evaluate the real and imaginary parts of the complex heavy quark potential. We have observed that the real part of the potential is found to be more screened, whereas the magnitude of the imaginary part of the potential gets increased on increasing the value of both temperature and magnetic field. In addition to this, we have observed that the real part gets slightly more screened while the imaginary part gets increased in the presence of a weak magnetic field as compared to their counterparts in the absence of a magnetic field (pure thermal). The increase in the screening of the real part of the potential leads to the decrease of binding energies of J=Ψ and ϒ, whereas the increase in the magnitude of the imaginary part leads to the increase of thermal width with the temperature and magnetic field both. Also the binding energy and thermal width in the presence of a weak magnetic field become smaller and larger, respectively, as compared to that in the pure thermal case. With the observations of binding energy and thermal width in hand, we have finally obtained the dissociation temperatures for J=Ψ and ϒ, which become slightly lower in the presence of a weak magnetic field. For example, with eB ¼ 0m 2 π the J=ψ and ϒ are dissociated at 1.80T c and 3.50T c , respectively, whereas with eB ¼ 0.5m 2 π they dissociated at slightly lower values 1.74T c and 3.43T c , respectively. This observation leads to the slightly early dissociation of quarkonia because of the presence of a weak magnetic field.

“…In the presence of the magnetic field, the photon self-energy contains a very rich structure and is also very complicated in general. There have been many field theoretic attempts to study the photon self-energy [26][27][28][29]; see also studies on gluon self-energy [30,31].…”

We study the photon self-energy in magnetized chiral plasma by solving the response of electromagnetic field perturbations in chiral kinetic theory with Landau level states. With lowest Landau level approximation and in the collisionless limit, we find solutions for three particular perturbations: the parallel electric, static perpendicular electric field, and static perpendicular magnetic field, corresponding to chiral magnetic wave, drift state, and tilted state, from which we extract components of photon self-energy in different kinematics. We that show no solution is possible for more general field perturbations. We argue that this is an artifact of the collisionless limit: while static solutions corresponding to the drift state and tilted state can be found, they cannot be realized dynamically without interaction between Landau levels. We also discuss the possible manifestation of side-jump effects due to both boost and rotation, with the latter due to the presence of background magnetic field.

“…The terms in the direction of U µ in ( 52) and ( 53) are the vector and axial Hall currents which are transverse to E µ ⊥ , b µ and u µ . The parts along the magnetic field in ( 48), ( 50) and ( 52) give the well-known CME at O(1), O(a) and O(∂a) separately, while those in ( 49), ( 51) and (53) give CSE.…”

“…The two-point function is important in its own right, e.g. the photon self-energy as a fundamental quantity characterizing the vacuum polarization by electromagnetic field has been intensively studied for magnetized plasma in field theory [47][48][49][50][51][52][53][54]. On the other hand, as a contrast to the full non-perturbative effective Lagrangian of vacuum for constant electromagnetic field established by Heisenberg and Euler [55] in the study of vacuum polarization, an effective action for the perturbative gauge fields in magnetized medium can also be constructed as the generating functional of the correlators.…”

We study the two-point functions from chiral kinetic theory which characterize the response to perturbative vector and axial gauge fields in magnetized chiral plasma. In the lowest Landau level approximation, the solution of chiral kinetic equations gives density waves of electric and axial charges, which contain chiral magnetic wave implied by the axial anomaly and magnetic field. We then obtain the constitutive relations for covariant currents and stress tensor that involving the density waves. By considering the difference between consistent and covariant anomalies explicitly, the correlators of consistent currents and stress tensor satisfy derivative symmetry, and therefore allow an effective action for the perturbative gauge fields as the generating functional of the correlators.We also verify the derivative symmetry of the correlators agrees with the Onsager relations.
