Strings at the Tachyonic Vacuum
, 2001
"... We study the worldvolume effective action of Dpbrane at the tachyonic vacuum which is equivalent to the zero tension limit. Using the Hamiltonian formalism we discuss the algebra of constraints and show that there is a nontrivial ideal of the algebra which corresponds to Virasoro like constraints ..."

Proof of vanishing cohomology at the tachyon vacuum
, 2006
"... We prove Sen’s third conjecture that there are no onshell perturbative excitations of the tachyon vacuum in open bosonic string field theory. The proof relies on the existence of a special state A, which, when acted on by the BRST operator at the tachyon vacuum, gives the identity. While this state ..."

String Field Theory Around the Tachyon Vacuum
, 2000
"... Assuming that around the tachyon vacuum the kinetic term of cubic open string field theory is made purely of ghost operators we are led to gauge invariant actions which manifestly implement the absence of open string dynamics around this vacuum. We test this proposal by showing the existence of lump ..."

Rolling to the tachyon vacuum in string field theory
, 2007
"... We argue that the rollingtachyon solution in cubic OSFT proceeds at late times to precisely the analytic tachyonvacuum solution constructed by Schnabl. In addition, we demonstrate the relationship between the rollingtachyon solution and the standard BCFT description by showing that there is a fin ..."

Tachyon vacuum in cubic superstring field theory
 JHEP 01 (2008) 013, [0707.4591]. (Cited on
"... In this paper we give an exact analytic solution for tachyon condensation in the modified (picture 0) cubic superstring field theory. We prove the absence of cohomology and, crucially, reproduce the correct value for the Dbrane tension. The solution is surprising for two reasons: First, the existen ..."

, the existence of a tachyon vacuum in this theory has not been definitively established in the level expansion. Second, the solution vanishes in the GSO(−) sector, implying a “tachyon
Tachyon Vacuum Solution in Open String Field Theory
, 804
"... We show that Schnabl’s tachyon vacuum solution is an exact solution of the equation of motion of Witten’s open bosonic string field theory in the background of constant antisymmetric twoform field. The action computed at the vacuum solution is given by the DiracBornInfeld factor multiplied to tha ..."

Observables for identitybased tachyon vacuum solutions
"... We consider a modified K Bc algebra in bosonic open string field theory expanded around identitybased scalar solutions. By use of the algebra, classical solutions on the background are constructed and observables for them, including energy densities and gaugeinvariant overlaps, are calculable. Th ..."

Fundamental strings in open string theory at the tachyonic vacuum,” hepth/0010240
"... We show that the worldvolume theory on a Dpbrane at the tachyonic vacuum has solitonic string solutions whose dynamics is governed by the NambuGoto action of a string moving in (25+1) dimensional spacetime. This provides strong evidence for the conjecture that at this vacuum the full (25+1) dim ..."
