String field theory
Did you know?
String field theory (SFT) is a formalism in string theory in which the dynamics of relativistic strings is reformulated in the language of quantum field theory. This is accomplished at the level of perturbation theory by finding a collection of vertices for joining and splitting strings, as well as string propagators, that … See more Light-cone string field theories were introduced by Stanley Mandelstam and developed by Mandelstam, Michael Green, John Schwarz and Lars Brink. An explicit description of the second-quantization of the light-cone string … See more An important step in the construction of covariant string field theories (preserving manifest Lorentz invariance) was the construction of a covariant kinetic term. This kinetic term … See more There are two main constructions of supersymmetric extensions of Witten's cubic open string field theory. The first is very similar in form to its bosonic cousin and is known as modified cubic superstring field theory. The second, due to Nathan Berkovits … See more A formulation of the NS sector of the heterotic string was given by Berkovits, Okawa and Zwiebach.

It describes the dynamics of … See more Covariant closed string field theories are considerably more complicated than their open string cousins. Even if one wants to construct a string field theory which only reproduces tree-level interactions between closed strings, the classical action must contain an infinite … See more • Conformal field theory • F-theory • Fuzzballs • List of string theory topics See more WebMar 27, 2024 · Beside string field theory, his contributions include works on black hole and supergravity, two-dimensional gravity, tensor models and applications of machine learning to theoretical physics.

WebJun 27, 2013 · 1 Answer. Sorted by: 5. Bosonic fields are "more significant" than fermionic fields because they may get large vacuum expectation values – from a condensate of many bosons in the same state. Consequently, there may exist a meaningful classical field theory limit. Massless fields are "more significant" than massive fields because the massive ... WebAlthough the methods of conformal field theory have given us a wealth of possible string vacuums and a framework in which to begin phenomenology, there are still severe deficiencies in this formulation. First, conformal field theory is necessarily a perturbative...
