Abstract We consider Sen's effective action for unstable D-branes, and study its classical dynamics exactly. In the true vacuum, the Hamiltonian dynamics remains well-defined despite a vanishing action, and is that of massive relativistic string fluid of freely moving electric flux lines. The energy (tension) density equals the flux density in the local co-moving frame. Furthermore, a finite dual Lagrangian exists and is related to the Nielsen–Olesen field theory of “dual” strings, supplemented by a crucial constraint. We conclude with discussion on the endpoint of tachyon condensation.

Rolling Tachyon (2002, background): “Π can be interpreted as the energy stored in the electric flux tube; indeed if during the evolution of the D-brane the excess energy leaves the plane of the brane leaving behind static electric flux tubes in the tachyon vacuum, then the energy stored in the flux tube will be exactly Π[27, 29, 31].”

Inflation from a tachyon fluid (2002, background): “According to Sen [2], (see also [4]), a rolling tachyon condensate in either bosonic or supersymmetric string theory can be described by a fluid which in the homogeneous limit has energy density”
