\nAbstract: We study a translation invarian
 t spin model in a three-dimensional regular lattice\, called the cubic cod
 e model\, in the presence of arbitrary extensive perturbations. Below a cr
 itical perturbation strength\, we show that most states with finite energy
  are localized\; the overwhelming majority of such states have energy conc
 entrated around a finite number of defects\, and remain so for a time that
  is near-exponential in the distance between the defects. This phenomenon 
 is due to an emergent superselection rule and does not require any disorde
 r. This is joint a joint work with Jeongwan haah.(1505.01480)\n\nhttps://q
