Electron electromagnetic-mass melting in strong fields

Electromagnetic Shocks in Strong Magnetic Fields

The nonlinear properties of electromagnetic waves traveling through a magnetized vacuum is of particular interest in the study of neutron stars. Heisenberg and Euler [1] and Weisskopf [2] first derived nonlinear corrections to the Maxwell equations of the electromagnetic field. Lutzky and Toll [3] and Zheleznyakov and Fabrikant [4] applied the weak-field expansion to show that shock waves can d...

Vacuum birefringence in strong inhomogeneous electromagnetic fields

Electron-electron interaction in strong electromagnetic fields: the two-electron contribution to the ground-state energy in He-like uranium.

Radiative recombination transitions into the ground state of cooled bare and hydrogenlike uranium ions were measured at the storage ring ESR. By comparing the corresponding x-ray centroid energies, this technique allows for a direct measurement of the electron-electron contribution to the ionization potential in the heaviest He-like ions. For the two-electron contribution to the ionization pote...

Disoriented Chiral Condensate and Strong Electromagnetic Fields

We discuss the effect of strong electromagnetic fields on chiral orientation in the framework of the linear σ model. Based on lessons we learn from computation of the effective potential at one loop, we argue that the chiral U(1) anomaly dominates chiral disorientation driven by electromagnetism. We show that the anomaly effect induces a quasi-instantaneous “kick” to field configurations along ...

Kinetics of Vacuum Pair Creation in Strong Electromagnetic Fields

We study vacuum particle antiparticle pair production under action of a strong time dependent space homogeneous electric field at the presence of a constant magnetic field. The kinetic equation for fermions and bosons was derived in the framework of the Schwinger mechanism of vacuum tunnelling. We show the enhancement of pair production for fermions (suppression for bosons) with the increasing ...
