Magnetic susceptibility of QCD at zero and at finite temperature from the lattice
Bali, G. S.; Bruckmann, F.; Constantinou, Martha; Costa, Marios Gil; Endrödi, Gergely; Katz, Sándor D.; Panagopoulos, Haralambos G.; Schäfer, A. (2012)The response of the QCD vacuum to a constant external (electro)magnetic field is studied through the tensor polarization of the chiral condensate and the magnetic susceptibility at zero and at finite temperature. We determine ...

Perturbative renormalization of staggered fermion operators with stout improvement: Application to the magnetic susceptibility of QCD
Bali, G. S.; Bruckmann, F.; Constantinou, Martha; Costa, Marios Gil; Endrödi, Gergely; Katz, Sándor D.; Panagopoulos, Haralambos G.; Schäfer, A. (Proceedings of Science (PoS), 2013)We calculate the fermion propagator and the quark-antiquark Green's functions for a complete set of ultralocal fermion bilinears, Γ [Γ: scalar (S), pseudoscalar (P), vector (V), axial (A) and tensor (T)], using perturbation ...

Thermodynamic properties of QCD in external magnetic fields
Bali, G. S.; Bruckmann, F.; Constantinou, Martha; Costa, Marios Gil; Endrödi, Gergely; Fodor, Zoltán; Katz, Sándor D.; Krieg, S.; Panagopoulos, Haralambos G.; Schäfer, A.; Szabó, Kálmán K. (2012)We consider the effect of strong external electromagnetic fields on thermodynamic observables in QCD, through lattice simulations with 1+1+1 flavors of staggered quarks at physical quark masses. Continuum extrapolated ...
