Maxwell equations in vacuum allow for solutions with a non-trivial topology in the electric
and magnetic field line configurations at any given moment in time. One example is a space …

In this article we discuss the properties of electromagnetic fields in heavy-ion collisions and
consequences for observables. We address quantitatively the issue of the magnetic field …

We present new simulations of decaying hydromagnetic turbulence for a relativistic equation
of state relevant to the early Universe. We compare helical and nonhelical cases either with …

Extremely magnetized neutron stars with magnetic fields as strong as∼ 10 15− 16 G, or
magnetars, have received considerable attention in the last decade due to their identification …

We study the dynamical evolution of the so-called chiral magnetic effect in an
electromagnetic conductor. To this end, we consider the coupled set of corresponding …

It has been pointed out that hypermagnetic helicity decay at the electroweak symmetry
breaking may have produced the observed baryon asymmetry of the Universe through the …

We show that if a quantum dot or Majorana zero mode couples to the chiral Majorana
fermions, a resonant exchange of chiral Majorana fermions can occur and leads to a non …

For the visualization of dense line fields, the careful selection of lines to be rendered is a
vital aspect. In this paper, we present a global line selection approach that is based on an …

We perform full-magnetohydrodynamics simulations on various initially helical
configurations and show that they reconfigure into a state where the magnetic field lines …

We introduce a topological flux function to quantify the topology of magnetic braids: non-
zero, line-tied magnetic fields whose field lines all connect between two boundaries. This …
