Here are some references for Haah's code and the larger world of "fractons". This list is far from complete and does not accurately capture the history of the subject.

In finite entropy systems such as black holes, real-time partition functions do not decay to zero at late times. It is a challenge to derive this non-decaying behavior starting from the path integral over the master fields of a large N theory. I...

Modern methods for computing scattering amplitudes getenormous mileage out of knowledge of (or, often, even assumptions about) their singularity structure. I will demonstrate how, in the case of N=4 SYM theory, information about this singularity...

Boundary state black holes are single sided pure black holeswith an End-of-the-World Brane cutting off the spacetime in the interior. I demonstrate that certain Hamiltonian deformations tuned to the black hole microstate inject negative energy...

The set of low-energy effective theories that do not admit an ultraviolet completion in string theory is known as the ``swampland." Developing criteria to determine which effective theories belong in the string landscape and which ones belong in...

The vacuum state reduced to a region of the space gives a density matrix which can be written in a thermal-like form. In this "thermal" density matrix the role of the Hamiltonian is played by the so called entanglement or modular Hamiltonian...

I will give an elementary introduction to neural network models commonly used in deep learning. These include feed-forward neural networks, recurrent neural networks and memory models. If time permits, a few open problems in the field will also be...

Gauging of bosonic and fermionic symmetry protected topological (SPT) states with discrete symmetry produces simple yet non-trivial topological quantum field theories (TQFTs). Some of the natural observables in such TQFTs are expectation values of...
