Cosmology with rolling tachyon

  • M. Sami
  • Pravabati Chingangbam
  • Tabish Qureshi


We examine the possibility of rolling tachyon to play the dual role of inflaton at early epochs and dark matter at late times. We argue that enough inflation can be generated with the rolling tachyon either by invoking the large number of branes or brane world assisted inflation. However, reheating is problematic in this model.
