Closed String Cohomology in Open String Field Theory
Nicolas Moeller, Ivo Sachs
We show that closed string states in bosonic string field theory are encoded in the cyclic cohomology of cubic open string field theory (OSFT) which, in turn, classifies the deform…
Delays in Open String Field Theory
Frederik Beaujean, Nicolas Moeller
We study the dynamics of light-like tachyon condensation in a linear dilaton background using level-truncated open string field theory. The equations of motion are found to be dela…
Bouncing universe and non-BPS branes
Philipp Höffer v. Loewenfeld, Jin U Kang, Nicolas Moeller +1
We describe string frame bouncing universe scenarios involving the creation and annihilation of a non-BPS D9-brane in type IIA superstring theory. We find several classes of soluti…
A tachyon lump in closed string field theory
Nicolas Moeller
We find a codimension one lump solution of closed bosonic string field theory. We consider vertices up to quartic order and include in the string field the tachyon, the ghost dilat…
Closed Bosonic String Field Theory at Quintic Order II: Marginal Deformations and Effective Potential
Nicolas Moeller
We verify that the dilaton together with one exactly marginal field, form a moduli space of marginal deformations of closed bosonic string field theory to polynomial order five. We…
Closed Bosonic String Field Theory at Quintic Order: Five-Tachyon Contact Term and Dilaton Theorem
Nicolas Moeller
We solve the geometry of the closed string field theory five-point vertex. Our solution is calculated in terms of quadratic Strebel differentials which are found numerically all ov…
