“…For instance, it contains the contribution of the intermediate π þ π − mesons or the ρ meson peak which has a large spectral weight in the confined phase [12]. It is reasonable to expect that the external magnetic field modifies the spectral function, for instance through the light meson masses modification [55][56][57][58]. Thus, in order to check the presence of CME in the confined phase one has to separate the contribution to the spectral function due to the conductivity, ω ∼ 0, from the contribution of the light mesons ω ∼ 2m π ; m ρ ; ….…”

We study the electromagnetic conductivity of QGP in a magnetic background by lattice simulations with N f ¼ 2 þ 1 dynamical rooted 2-stout smeared staggered fermions at the physical point. We study the correlation functions of the electromagnetic currents at T ¼ 200, 250 MeV and use the Tikhonov approach to extract the conductivity. The conductivity is found to rise with the magnetic field in the parallel direction and to decrease in the transverse direction, giving evidence for both the chiral magnetic effect and the magnetoresistance phenomenon in QGP. We also estimate the chiral charge relaxation time in QGP.

“…The calculation of hadron masses is a strong area of lattice QCD. The mass shifts in the magnetic fields were investigated for many hadrons: pseudo-scalar mesons [10,11,12,13,14,15,16,17], vector mesons [11,12,13,15,18,19], and nucleons [20,21,22]. The calculation is straightforward in most cases.…”

This is an introductory review of lattice QCD with external fields. The study of external magnetic fields is one of the greatest achievements in modern lattice QCD. Large-scale simulations and detailed analyses have revealed intriguing properties of QCD in the magnetic fields. The study of external electric fields is more challenging because of a technical difficulty. We overview the successes and challenges of the lattice simulations with the electromagnetic fields. We also introduce a newly developing field, the lattice simulation of rotating QCD matters.

“…The electromagnetic structure of hadrons has been the target of LQCD investigations since the 1980s; the first LQCD computations of the nucleon's response to uniform magnetic fields were performed in the quenched approximation, starting with calculations of the nucleon magnetic moments [204,205,475,476], and more recently extending to other baryons in the baryon octet [477] and decuplet [478,479]. A series of subsequent calculations were able to extract not only magnetic moments, but also polarizabilities, for several members of the lowest-lying baryon and meson octets [480][481][482][483][484][485][486][487][488][489][490][491][492][493][494]. Computations of EM properties involving more than one hadron have only been achieved recently, with the first calculation of the leading contribution to the magnetic-field response of s-shell nuclei being presented in Ref.…”
