Description
Strong magnetic fields occur across the universe in several physical
systems. This is the case for magnetars, heavy-ion collisions and the
primordial universe. These fields are strong enough to have an impact
on the interactions at the QCD scale. In this work, we applied lattice
QCD simulations to gain new insights into how QCD thermodynamics
is affected by the presence of a background magnetic field. We
simulated 2 + 1 flavors of staggered quarks with physical masses and considered
both uniform and non-uniform magnetic fields to study the effect of
such backgrounds on a series of QCD observables. In particular, we focus
on the phase diagram, steady currents and the magnetic susceptibility.
