Deconfinement transition in two-flavour lattice QCD with dynamical overlap fermions in an external magnetic field

Understand

We study the influence of an external magnetic field on the deconfinement transition in two-flavour lattice QCD with physical quark charges.

• We use dynamical overlap fermions without any approximation such as fixed topology and perform simulations on a $16^3 \times 6$ lattice and at a pion mass around $500MeV$.
• The pion mass (as well as the lattice spacing) was determined in independent runs on $12^3 \times 24$ lattices.
• We consider two temperatures, one of which is close to the deconfinement transition and one which is above.
