This week I have been continuing my collaborative work on the matrix elements of the Hamiltonian Constraint in LQG, see the posts:

#### 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

#### A Mission of Gravity

One of the seminal novels to come out of the Golden Age of science fiction was a book by Hal Clement entitled A Mission of Gravity… 507 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
