Title: Emergent Gravity from Spinfoam Models
Abstract: Recently, many
new insights of quantum gravity are brought by the program of emergent
gravity from quantum information. An idea in this
program is that gravity, which is geometrical and smooth, might emerge
as low energy excitations from fundamentally entangled qubits (or
generally qudits), which are algebraic and discrete. In this talk, I
demonstrate that spinfoam models, on one hand, are
made fundamentally by entangled qudits, while on the other hand, emerge
smooth gravitational fields in a low energy limit. The result suggests
the spinfoam model to be a working example of the above idea in the
emergent gravity program.
