Cosmological unification of string theories
Simeon Hellerman, Ian Swanson
We present an exact solution of superstring theory that interpolates in time between an initial type 0 phase and a final phase whose physics is exactly that of the bosonic string.…
Connecting giant magnons to the pp-wave: An interpolating limit of
Juan Maldacena, Ian Swanson
We consider a particular large-radius limit of the worldsheet -matrix for strings propagating on . This limiting theory interpolates smoothly between the so-ca…
Dimension-changing exact solutions of string theory
Simeon Hellerman, Ian Swanson
Superstring theories in the critical dimension D=10 are connected to one another by a well-explored web of dualities. In this paper we use closed-string tachyon condensation to con…
Cosmological solutions of supercritical string theory
Simeon Hellerman, Ian Swanson
We study quintessence-driven, spatially flat, expanding FRW cosmologies that arise naturally from string theory formulated in a supercritical number of spacetime dimensions. The tr…
Integrable twists in AdS/CFT
Tristan McLoughlin, Ian Swanson
A class of marginal deformations of four-dimensional N=4 super Yang-Mills theory has been found to correspond to a set of smooth, multiparameter deformations of the S^5 target subs…
