Recent developments in superstring theory. [PDF]

open access: yesProc Natl Acad Sci U S A, 1998
There have been many remarkable developments in our understanding of superstring theory in the past few years, a period that has been described as “the second superstring revolution.” In particular, what once appeared to be five distinct theories are now recognized to be different manifestations of a single (unique) underlying theory.

A superstring field theory for supergravity [PDF]

open access: yesJournal of High Energy Physics, 2017
A covariant closed superstring field theory, equivalent to classical tendimensional Type II supergravity, is presented. The defining conformal field theory is the ambitwistor string worldsheet theory of Mason and Skinner.

Soft theorems in superstring theory [PDF]

open access: yesJournal of High Energy Physics, 2017
We use insights from superstring field theory to prove the subleading soft graviton theorem for tree amplitudes of (compactified) heterotic and type II string theories for arbitrary number of finite energy NS (NSNS) sector external states but only one ...

Boundary superstring field theory [PDF]

open access: greenNuclear Physics B, 2001
Using the Batalin-Vilkovisky formalism we provide a detailed analysis of the NS sector of boundary superstring field theory. We construct explicitly the relevant BV structure and derive the master action. Furthermore, we show that this action is exactly equal to the superdisk worldsheet partition function as was recently conjectured.

RECENT PROGRESS IN SUPERSTRING THEORY

open access: greenThe Ninth Marcel Grossmann Meeting, 2002
Superstring theory has continued to develop at a rapid clip in the past few years. Following a quick review of some of the major discoveries prior to 1998, this talk focuses on a few of the more recent developments. The topics I have chosen to present are 1) the use of K-theory to classify conserved charges carried by D-branes; 2) tachyon condensation ...

Supersymmetry in open superstring field theory [PDF]

open access: yesJournal of High Energy Physics, 2017
We realize the 16 unbroken supersymmetries on a BPS D-brane as invariances of the action of the corresponding open superstring field theory. We work in the small Hilbert space approach, where a symmetry of the action translates into a symmetry of the ...

D=5 holomorphic Chern-Simons and the pure spinor superstring

open access: yesJournal of High Energy Physics, 2023
The physical states of D=5 holomorphic Chern-Simons theory correspond to on-shell D=10 open superstring states in the cohomology of q +, where q + is one of the 16 spacetime supersymmetry generators.

Theory of ultracold superstrings [PDF]

open access: yesPhysical Review A, 2006
The combination of a vortex line in a one-dimensional optical lattice with fermions bound to the vortex core makes up an ultracold superstring. We give a detailed derivation of the way to make this supersymmetric string in the laboratory. In particular, we discuss the presence of a fermionic bound state in the vortex core and the tuning of the laser ...
