Holographic Space-Time: The Takeaway
TL;DR: The theory of holographic space-time (HST) generalizes both string theory and quantum field theory as mentioned in this paper, and it provides a geometric rationale for supersymmetry (SUSY) and a formalism in which super-Poincare invariance follows from Poincare-invariant invariance.

Abstract: The theory of holographic space-time (HST) generalizes both string theory and quantum field theory. It provides a geometric rationale for supersymmetry (SUSY) and a formalism in which super-Poincare invariance follows from Poincare invariance. HST unifies particles and black holes, realizing both as excitations of non-commutative geometrical variables on a holographic screen. Compact extra dimensions are interpreted as finite dimensional unitary representations of super-algebras, and have no moduli. Full field theoretic Fock spaces, and continuous moduli are both emergent phenomena of super-Poincare invariant limits in which the number of holographic degrees of freedom goes to infinity. Finite radius de Sitter (dS) spaces have no moduli, and break SUSY with a gravitino mass scaling like $\Lambda^{1/4}$. We present a holographic theory of inflation and fluctuations. The inflaton field is an emergent concept, describing the geometry of an underlying HST model, rather than "a field associated with a microscopic string theory". We argue that the phrase in quotes is meaningless in the HST formalism.

Interferometric Tests of Planckian Quantum Geometry Models
Ohkyung Kwon,Craig J. Hogan +1 more
TL;DR: In this article, the effect of Planck scale quantum geometrical effects on measurements with interferometers is estimated with standard physics, and with a variety of proposed extensions, and it is shown that effects are negligible in standard field theory with canonically quantized gravity.

The Holographic Space-Time Model of Cosmology
Tom Banks,Willy Fischler +1 more
TL;DR: In this paper, the authors outline the Holographic Space-time (HST) theory of cosmology and its relation to conventional theories of inflation, and show that the HST model predicts an early era of structure formation, prior to the Big Bang.

Holographic Fluctuations from Unitary de Sitter Invariant Field Theory
TL;DR: In this paper, the holographic theory of inflation provides a physical context for what is often called dS/CFT, which is a quantum theory which, in the limit of a large number of e-foldings, gives rise to a field theory on $S^3$, which is the representation space for a unitary representation of SO(1,4).

Instantons, Twistors, and Emergent Gravity
TL;DR: In this article, a new dual matrix formulation of N = 4 gauge theory on S(4) was proposed by taking the low energy limit of a holomorphic Chern-Simons theory on CP(3|4), in the presence of a large instanton flux.

Notes on black-hole evaporation
TL;DR: In this paper, the authors examined various aspects of black-hole evaporation and proposed a technique for replacing the collapse by boundary conditions on the past horizon, which retains the essential features of the collapse while eliminating some of the difficulties.
M theory as a matrix model: A conjecture
TL;DR: In this paper, it was shown that the membrane states required by the supersymmetric matrix quantum mechanics are contained as excitations of the matrix model, which is a non-perturbative realization of the holographic principle.
Thermodynamics of spacetime: The Einstein equation of state.
TL;DR: The Einstein equation is derived from the form of black hole entropy together with the fundamental relation $\delta Q=TdS$ connecting heat, entropy, and temperature, and its validity is seen to depend on the existence of local equilibrium conditions.

On the origin of gravity and the laws of Newton
TL;DR: In this article, the authors present a heuristic argument that shows that Newton's law of gravitation naturally arises in a theory in which space emerges through a holographic scenario and gravity is identified with an entropic force caused by changes in the information associated with the positions of material bodies.
