SUMMARY:Scaling properties of cosmic superstring networks - Martins\, C (C

DESCRIPTION:I will use a combination of state-of-the-art numerical simulat
 ions and analytic modeling to characterize the scaling properties of cosmi
 c superstring networks. Particular attention will be given to the role of 
 extra degrees of freedom in the evolution of these networks. Compared to t
 he 'plain vanilla' case of Goto-Nambu strings\, three such extensions play
  important but distinct roles in the network dynamics: the presence of cha
 rges/currents on the string worldsheet\, the existence of junctions\, and 
 the possibility of a hierarchy of string tensions. I will also comment on 
 insights gained from studying simpler defect networks\, including Goto-Nam
 bu strings themselves\, domain walls and semilocal strings.\n\n
