A Closed String Tachyon Vacuum ?
Haitang Yang, Barton Zwiebach
In bosonic closed string field theory the "tachyon potential" is a potential for the tachyon, the dilaton, and an infinite set of massive fields. Earlier computations of the potent…
Rolling Closed String Tachyons and the Big Crunch
Haitang Yang, Barton Zwiebach
We study the low-energy effective field equations that couple gravity, the dilaton, and the bulk closed string tachyon of bosonic closed string theory. We establish that whenever t…
Testing Closed String Field Theory with Marginal Fields
Haitang Yang, Barton Zwiebach
We study the feasibility of level expansion and test the quartic vertex of closed string field theory by checking the flatness of the potential in marginal directions. The tests, w…
Dilaton Deformations in Closed String Field Theory
Haitang Yang, Barton Zwiebach
The dilaton theorem implies that the contribution to the dilaton potential from cubic interactions of all levels must be cancelled by the elementary quartic self-coupling of dilato…
