SUMMARY:Magnetic penetration depth of iron-pnictides in case of coexis
 tence between superconducting and spin-density wave orders\, Condensed
  Matter Theory Group Seminar\, Dushko Kuzmanovski\, UW-Madison
DESCRIPTION:We obtain an analytic expression for the response function
  of a superconductor to an external vector  potential in the London li
 mit. We work within the framework of a two-band model with both intra-
  and interband pairings leading to superconducting (SC) and spin-densi
 ty wave (SDW) orders\, and assume that the mean-field approach is vali
 d. For definiteness\, we assume a homogeneous s+- SC order parameter\,
  and a commensurate SDW order parameter. We numerically solve the rele
 vant coupled self-consistency conditions in the zero-temperature limit
  for the two order parameters\, and use those solutions to calculate t
 he London penetration depth dependence on doping\, modeled by a doping
 -dependent anisotropic band-splitting. This would serve as a prelimina
 ry guide into future investigation of possible features in the tempera
 ture dependence of the London penetration depth\, found in recent expe
 riments.
