N2 - We compute the phase diagram of the quark-meson model at finite temperature, finite baryon chemical potential μ B = 3μ and constant external magnetic field B, using the functional renormalization group. Our results show that the critical temperature increases as a function of B at μ = 0, but for values μ larger than about 210 - 225 MeV, the opposite behavior is realized. As the magnetic field increases, the critical point (T*, μ *) moves from large μ , small T towards small μ , larger T in the μ -T phase diagram.
