The non-critical string theory describes the relativistic string without enforcing the critical dimension. Although this allows the construction of a...

'Superstring theory' is a shorthand for supersymmetric string theory because unlike bosonic string theory, it is the version of string theory that accounts...

Bosonic string theory is the original version of string theory, developed in the late 1960s. It is so called because it contains only bosons in the spectrum...

Usually non-critical string theory is considered in frames of the approach proposed by Polyakov. The other approach has been developed in. It represents...

Edward Witten first conjectured the existence of such a theory at a string theory conference at the University of Southern California in 1995. Witten's...

physics, type II string theory is a unified term that includes both type IIA strings and type IIB strings theories. Type II string theory accounts for two...

In theoretical physics, type I string theory is one of five consistent supersymmetric string theories in ten dimensions. It is the only one whose strings...

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...

quantum field theory, a nonlinear σ model describes a field Σ that takes on values in a nonlinear manifold called the target manifold  T. The non-linear σ-model...

In physics, a string is a physical entity postulated in string theory and related subjects. Unlike elementary particles, which are zero-dimensional or...

In string theory, a heterotic string is a closed string (or loop) which is a hybrid ('heterotic') of a superstring and a bosonic string. There are two...

In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called...

In string theory, the string theory landscape (or landscape of vacua) is the collection of possible false vacua, together comprising a collective "landscape"...

In physics, a Dirac string is a one-dimensional curve in space, conceived of by the physicist Paul Dirac, stretching between two hypothetical Dirac monopoles...

In non-technical terms, M-theory presents an idea about the basic substance of the universe. Although a complete mathematical formulation of M-theory is...

manifolds are important in string theory. They break the original supersymmetry to 1/8 of the original amount. For example, M-theory compactified on a G 2...

considered the worldvolume theory of a large number of D0-branes in Type IIA string theory. In geometry, it is often useful to introduce coordinates. For example...

theoretical physics, F-theory is a branch of string theory developed by Iranian-American physicist Cumrun Vafa. The new vacua described by F-theory were discovered...

common 4D of space and time and considered an important precursor to string theory. In their setup, the vacuum has the usual 3 dimensions of space and...

of Riemannian holonomy groups first raised the issue of the existence of non-symmetric manifolds with holonomy Sp(n)·Sp(1). Interesting results were proved...

of partial differential equations, established a comprehensive existence theory for Ricci-flat metrics in the special case of Kähler metrics on closed complex...

The holographic principle is a property of string theories and a supposed property of quantum gravity that states that the description of a volume of...

(supergravity theory; SUGRA for short) is a modern field theory that combines the principles of supersymmetry and general relativity; this is in contrast to non-gravitational...
