Dual Graviton In theoretical physics, the dual graviton is a hypothetical elementary particle that is a dual of the graviton under electricmagnetic duality predicted by some formulations of supergravity in eleven dimensions.[3] The dual graviton was first hypothesized in 1980 (in a paper received by the journal on Einstein's 101st birthday).[4] It was theoretically modeled in 2000s,[1][2] which was then predicted in elevendimensional mathematics of SO(8) supergravity in the framework of electricmagnetic duality.[3] It again emerged in the E11 generalized geometry in eleven dimensions,[5] and the E7 generalized vielbeinegeometry in eleven dimensions.[6] While there is no local coupling between graviton and dual graviton, the field introduced by dual graviton may be coupled to a BF model as nonlocal gravitational fields in extra [...More...]  "Dual Graviton" on: Wikipedia Yahoo

Conformal Field Theory A conformal field theory (CFT) is a quantum field theory that is invariant under conformal transformations. In two dimensions, there is an infinitedimensional algebra of local conformal transformations, and conformal field theories can sometimes be exactly solved or classified. Conformal field theory has important applications[1] to condensed matter physics, statistical mechanics, quantum statistical mechanics, and string theory. Statistical and condensed matter systems are indeed often conformally invariant at their thermodynamic or quantum critical points.Contents1 Scale invariance vs. conformal invariance 2 Dimensional considerations2.1 Two dimensions 2.2 More than two dimensions3 Conformal symmetry 4 See also 5 References 6 Further reading Scale invariance vs [...More...]  "Conformal Field Theory" on: Wikipedia Yahoo 

Twistor String Theory Twistor string theory Twistor string theory is an equivalence between N = 4 supersymmetric Yang–Mills theory and the perturbative topological B model string theory in twistor space.[1] It was initially proposed by Edward Witten Edward Witten in 2003. Twistor theory Twistor theory was introduced by Roger Penrose Roger Penrose from the 1960s as a new approach to the unification of quantum theory with gravity. Twistor space is a threedimensional complex projective space in which physical quantities appear as certain structural deformations. Spacetime and the familiar physical fields emerge as consequences of this description. But twistor space is chiral (handed) with left and righthanded objects treated differently [...More...]  "Twistor String Theory" on: Wikipedia Yahoo 

N = 4 Supersymmetric Yang–Mills Theory N = 4 supersymmetric Yang–Mills (SYM) theory is a mathematical and physical model created to study particles through a simple system, similar to string theory, with conformal symmetry. It is a simplified toy theory based on Yang–Mills theory Yang–Mills theory that does not describe the real world, but is useful because it can act as a proving ground for approaches for attacking problems in more complex theories.[1] It describes a universe containing boson fields and fermion fields which are related by 4 supersymmetries (this means that swapping boson, fermion and scalar fields in a certain way leaves the predictions of the theory invariant). It is one of the simplest (because it has no free parameters except for the gauge group) and one of the few finite quantum field theories in 4 dimensions [...More...]  "N = 4 Supersymmetric Yang–Mills Theory" on: Wikipedia Yahoo

Monstrous Moonshine In mathematics, monstrous moonshine, or moonshine theory, is the unexpected connection between the monster group M and modular functions, in particular, the j function. The term was coined by John Conway and Simon P. Norton in 1979. It is now known that lying behind monstrous moonshine is a vertex operator algebra called the moonshine module (or monster vertex algebra) constructed by Igor Frenkel, James Lepowsky, and Arne Meurman in 1988, having the monster group as symmetries. This vertex operator algebra is commonly interpreted as a structure underlying a twodimensional conformal field theory, allowing physics to form a bridge between two mathematical areas [...More...]  "Monstrous Moonshine" on: Wikipedia Yahoo
