This study evaluates the performance of ChatGPT variants, GPT-3.5 and GPT-4, both with and without prompt engineering, against solely student work and a mixed category containing both student and GPT-4 contributions in university-level physics coding...

Emergent dark gravity from (non)holographic screens (2019)
Journal Article
Peach, A. (2019). Emergent dark gravity from (non)holographic screens. Journal of High Energy Physics, 2019(2), Article 51. https://doi.org/10.1007/jhep02%282019%29151

In this work, a clear connection is made between E. Verlinde’s recent theory of emergent gravity in de Sitter space, and the earlier work describing emergent gravity using holographic screens. A modified (non)holographic screen scenario is presented,... Read More about Emergent dark gravity from (non)holographic screens.

Tensor network models of multiboundary wormholes (2017)
Journal Article
Peach, A., & Ross, S. F. (2017). Tensor network models of multiboundary wormholes. Classical and Quantum Gravity, 34(10), Article 105011. https://doi.org/10.1088/1361-6382/aa6b0f

We study the entanglement structure of states dual to multiboundary wormhole geometries using tensor network models. Perfect and random tensor networks tiling the hyperbolic plane have been shown to provide good models of the entanglement structure i...

Hot multiboundary wormholes from bipartite entanglement (2015)
Journal Article
Marolf, D., Maxfield, H., Peach, A., & Ross, S. (2015). Hot multiboundary wormholes from bipartite entanglement. Classical and Quantum Gravity, 32(21), https://doi.org/10.1088/0264-9381/32/21/215006

We analyze the 1+1 CFT states dual to hot (time-symmetric) 2+1 multiboundary AdS wormholes. These are black hole geometries with high local temperature, $n\geqslant 1$ asymptotically-AdS3 regions, and arbitrary internal topology. The dual state at t...

Schrödinger holography with z = 2 (2015)
Journal Article
Andrade, T., Keeler, C., Peach, A., & Ross, S. (2015). Schrödinger holography with z = 2. Classical and Quantum Gravity, 32(8), https://doi.org/10.1088/0264-9381/32/8/085006

We investigate holography for asymptotically Schrödinger spacetimes, using a frame formalism based on the anisotropic scaling symmetry. We build on our previous work on $z\lt 2$ to propose a dictionary for z = 2. For z = 2, the scaling symmetry does... Read More about Schrödinger holography with z = 2.

Schrödinger holography for z<2 (2015)
Journal Article
Andrade, T., Keeler, C., Ross, S., & Peach, A. (2015). Schrödinger holography for z

We investigate holography for asymptotically Schrödinger spacetimes, using a frame formalism. Our dictionary is based on the anisotropic scaling symmetry. We consider z < 2, where the holographic dictionary is cleaner; we make some comments on z = 2.... Read More about Schrödinger holography for z<2.
