Exempel på hur man kan använda SUPERGRAVITY i en mening

• Between 1970 and 2000, Kaku had papers published in physics journals covering topics such as superstring theory, supergravity, supersymmetry, and hadronic physics.
• In theoretical physics, supergravity (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 supersymmetric theories such as the Minimal Supersymmetric Standard Model.
• Michael James Duff FRS, FRSA is a British theoretical physicist and pioneering theorist of supergravity who is the Principal of the Faculty of Physical Sciences and Abdus Salam Chair of Theoretical Physics at Imperial College London.
• In 1995, Polchinski identified D-branes with black p-brane solutions of supergravity, a discovery that triggered the Second Superstring Revolution and led to both holographic and M-theory dualities.
• Thus the gravitino is the fermion mediating supergravity interactions, just as the photon is mediating electromagnetism, and the graviton is presumably mediating gravitation.
• At low energies, type IIB string theory is described by type IIB supergravity in ten dimensions which is a chiral theory (left–right asymmetric) with (2,0) d=10 supersymmetry; the fact that the anomalies in this theory cancel is therefore nontrivial.
• In physics, Killing spinors are used in supergravity and superstring theory, in particular for finding solutions which preserve some supersymmetry.
• Stueckelberg type couplings arise quite naturally in theories involving compactifications of higher-dimensional string theory, in particular, these couplings appear in the dimensional reduction of the ten-dimensional N = 1 supergravity coupled to supersymmetric Yang–Mills gauge fields in the presence of internal gauge fluxes.
• He is portrayed as a brilliant theoretical physicist and cosmologist, who researches supersymmetry, string theory, 11-dimensional supergravity theory, doubly special relativity, black holes, Ly-alpha emitters, the cosmic microwave background, and gravitational waves, using LIGO to check predictions on quantum corrections.
• The Quantum Gravity and Unified Theories department (acting director since August 2020: Alessandra Buonanno) at AEI Potsdam works on the development of a quantum theory of gravity, based on conformal field theory, string theory, and supergravity and symmetries.
• It turns out that the standard notion of spin structure is too restrictive for applications to supergravity and string theory, and that the correct notion of spinorial structure for the mathematical formulation of these theories is a "Lipschitz structure".
• In 2004 PASCOS symposium held a special Pran Nath Festschrift honouring his "pioneering contributions over four decades in the fields of high energy theory, supersymmetry, supergravity, and unification".
• The self-duality condition cannot be imposed by a Lagrangian without either introducing extra fields or ruining the manifest super-Poincaré invariance of the theory, thus type IIB supergravity is considered to be a non-Lagrangian theory.
• In 1978, together with Eugène Cremmer and Bernard Julia, Scherk constructed the Lagrangian and supersymmetry transformations for eleven-dimensional supergravity, which is one of the foundations of M-theory.
• He is known for the proposal of the para-string theory, construction of modular invariant partition functions for WZNW models via the orbifold method, classification of eleven-dimensional supergravity solutions with a quotient structure, and discovery of non-commutativity in D-branes of string theory.
• In 1978, together with Bernard Julia and Joël Scherk, he co-developed eleven-dimensional supergravity theory and proposed a mechanism of spontaneous compactification in field theory.
• Separated fivebranes that preserve a certain fraction of supersymmetry and wiggle in space are well-described by supergravity solutions of Lunin and Mathur.
• Objects of study include superalgebras (such as super Minkowski space and super-Poincaré algebra), superschemes, supermetrics/supersymmetry, supermanifolds, supergeometry, and supergravity, namely in the context of superstring theory.
• Gauged supergravity is a supergravity theory in which some R-symmetry is gauged such that the gravitinos (superpartners of the graviton) are charged with respect to the gauge fields.
• His research interests are Yang-Mills gauge theories, supersymmetry, supergravity, quaternion and octonion algebras, spin structures, generalised theories of gravity, cosmological solutions, integrable systems and phase space quantisation.
