Emergent Gravity and Noncommutative Branes from Yang-Mills Matrix Models
The framework of emergent gravity arising from Yang-Mills matrix models is developed further, for general noncommutative branes embedded in R. The effective metric on the brane turns out to have a universal form reminiscent of the open string metric, depending on the dynamical Poisson structure and the embedding metric in R. A covariant form of the tree-level equations of motion is derived, and...
متن کاملNoncommutative Gravity
Various approaches by the author and collaborators to define gravitational fluctuations associated with a noncommutative space are reviewed. Geometry of a noncommutative space is defined by the data (A, H,D) where A is a noncommutative involutive algebra, H is a separable Hilbert space and D a self-adjoint operator on H referred to as Dirac operator [1]. Geometry on Riemannian manifolds could b...
متن کاملThe Fermion Doubling Problem and Noncommutative Geometry
We propose a resolution for the fermion doubling problem in discrete field theories based on the fuzzy sphere and its Cartesian products. The nonperturbative formulation of chiral gauge theories is a long standing programme in particle physics. It seems clear that one should regularise these theories with all symmetries intact. There are two major problems associated with conventional lattice a...
متن کاملNoncommutative Spacetime and Emergent Gravity
We argue that a field theory defined on noncommutative (NC) spacetime should be regarded as a theory of gravity, which we refer to as the emergent gravity. A whole point of the emergent gravity is essentially originated from the basic property: A NC spacetime is a (NC) phase space. This fact leads to two important consequences: (I) A NC field theory can basically be identified with a matrix mod...
متن کاملNonsymmetric Gravity and Noncommutative Signals *
Models in which the space-time metric g µν is not symmetric, i.e. g µν = g νµ may make predictions in scattering experiments, for example in a future e + e − linear collider, similar to those from noncommutative field theory. We compute the differential cross sections for pair annihilation , Bhabha and Møller scattering and find that both nonsymmetric gravity theory(NGT) and noncommutative fiel...
