Matrix Elements of Lorentzian Hamiltonian Constraint in LQG by Alesci,Liegener and Zipfel

This week I have been studying a number of papers about the Hamiltonian constraint operator in Loop Quantum Gravity. I’ll be reviewing these papers over the next few posts. 2,080 more words

Numerical work with Sagemath 17: Exploring curvature

This post is just a bit of informal exploration of the LQG curvature operator which I’ve been doing in preparation for a more formal attack during the next week. 105 more words

Continuous symmetries in discrete space?

Violating Lorentz symmetries can be dangerous. A new model assesses this threat in loop quantum gravity.

Discrete space is attractive in quantization attempts of gravity, but it implies the great danger of violating Lorentz transformations. 323 more words

Asymptotic flatness and quantum geometry

From the perspective of quantum gravity, the spacetime is smooth only in an effective sense, and is expected to exhibit a discrete structure at suitably small length scales. 417 more words

The length operator in Loop Quantum Gravity by Bianchi

This week I have been reading about the curvature operator in Loop Quantum Gravity. In this post I want to look at the length operator in LQG by Bianchi – which is important in understanding the curvature operator.  2,139 more words
