I review the origin and properties of electromagnetic fields produced in heavy‐ion collisions.
The field strength immediately after a collision is proportional to the collision energy and …

The early 21st century is witnessing a breakthrough in the study of the thermal radiation of
neutron stars. Observations with modern space telescopes have provided a wealth of …

It is well known that in noncentral heavy ion collisions a transient strong magnetic field is
generated in the direction perpendicular to the reaction plane. The maximal strength of this …

We study the impact of a magnetic field, generated in collisions of relativistic heavy ions, on
the decay probability of a quarkonium produced in the central rapidity region. The quark and …

We revisit the photon polarization tensor in a homogeneous external magnetic or electric
field. The starting point of our considerations is the momentum space representation of the …

We study the relativistic quark-antiquark system embedded in a magnetic field (MF). The
Hamiltonian containing confinement, one gluon exchange, and spin-spin interaction is …

Perturbative gluon exchange interaction between quark and antiquark, or in a 3 q system, is
enhanced in a magnetic field and may cause vanishing of the total qq¯ or 3 q mass, and …

We consider a simple nonlinear (quartic in the fields) gauge-invariant modification of
classical electrodynamics, to show that it possesses a regularizing ability sufficient to make …

A superstrong magnetic field stimulates the spontaneous production of positrons by naked
nuclei by diminishing the value of the critical charge Z cr. The recently discovered …

Hadron decay widths are shown to increase in strong magnetic fields as Γ (eB)∼ eB κ Γ (0).
The same mechanism is shown to be present in the production of the sea quark pair inside …
