A new matrix model is described, based on the exceptional Jordan algebra. The action is cubic, as in matrix Chern-Simons theory. We describe a compactification that, we argue, reproduces, at the one loop level, an octonionic compactification of the matrix string theory in which SO(8) is broken to G2. There are 27 matrix degrees of freedom, which under Spin(8) transform as the vector, spinor and conjugate spinor, plus three singlets, which represent the two longitudinal coordinates plus an… 

The Geometry of Jordan Matrix Models

We elucidate the geometry of matrix models based on simple formally real Jordan algebras. Such Jordan algebras give rise to a nonassociative geometry that is a generalization of Lorentzian geometry.

Matrix Model

It is of great interest that the properties of the product space Jc ×G, in which the degrees of freedom of the model live, are very similar to those of the physical Hilbert space.

E6 Matrix Model

We consider a new matrix model based on the simply connected compact exceptional Lie group E6. A matrix Chern-Simons theory is directly derived from the invariant on E6 .I t is asserted that an

Matrix universality of gauge field and gravitational dynamics

A simple cubic matrix model is presented, which has truncations that, it is argued, lead at the classical level to a variety of theories of gauge fields and gravity. These include Chern-Simons theory

On the Large N Limit of Exceptional Jordan Matrix Models, Chern-Simons Foliations and M, F Theory

The large N → ∞ limit of the Exceptional F4, E6 Jordan Matrix Models of Smolin-Ohwashi leads to a novel Chern-Simons Membrane Lagrangian which is the suitable candidate Lagrangian for

Trace dynamics and division algebras: towards quantum gravity and unification

Abstract We have recently proposed a Lagrangian in trace dynamics at the Planck scale, for unification of gravitation, Yang–Mills fields, and fermions. Dynamical variables are described by odd-grade

Exceptional Jordan Strings/Membranes and Octonionic Gravity/p-branes

Nonassociative Octonionic Ternary Gauge Field Theories are revisited paving the path to an analysis of the many physical applications of Exceptional Jordan Strings/Membranes and Octonionic Gravity.



The cubic matrix model and a duality between strings and loops

We find evidence for a duality between the standard matrix formulations of M theory and a background independent theory which extends loop quantum gravity by replacing SU(2) with a supersymmetric and

The Ashtekar Formulation for Canonical N = 2 Supergravity

We extend the Ashtekar formulation of canonical gravity to N=2 supergravity. The action has a complex first-order chiral form and is invariant under two local supersymmetry transformations. Since we

Matrix string theory

M theory as a matrix model: A Conjecture

We suggest and motivate a precise equivalence between uncompactified 11-dimensional M theory and the N={infinity} limit of the supersymmetric matrix quantum mechanics describing D0 branes. The

Finite Lorentz transformations, automorphisms, and division algebras

An explicit algebraic description of finite Lorentz transformations of vectors in ten‐dimensional Minkowski space is given by means of a parametrization in terms of the octonions. The possible
