The Einstein Tensor from UV-regulated Field Correlations
Matheus H. Zambianco, Achim Kempf
It is known that the spacetime metric can be recovered from quantum-field correlators. We extend this programme by showing that the Einstein tensor can be directly written in terms…
Trapped by simplicity: When Transformers fail to learn from noisy features
Evan Peters, Ando Deng, Matheus H. Zambianco +2
Noise is ubiquitous in data used to train large language models, but it is not well understood whether these models are able to correctly generalize to inputs generated without noi…
Emergent metric from wavelet-transformed quantum field theory
Šimon Vedl, Daniel J. George, Fil Simovic +5
We introduce a method of reverse holography by which a bulk metric is shown to arise from locally computable multiscale correlations of a boundary quantum field theory (QFT). The m…
Lorentzian Spectral Geometry with Causal Sets
Yasaman K. Yazdi, Marco Letizia, Achim Kempf
We study discrete Lorentzian spectral geometry by investigating to what extent causal sets can be identified through a set of geometric invariants such as spectra. We build on prev…
Learning to Utilize Correlated Auxiliary Noise: A Possible Quantum Advantage
Aida Ahmadzadegan, Petar Simidzija, Ming Li +1
This paper has two messages. First, we demonstrate that neural networks that process noisy data can learn to exploit, when available, access to auxiliary noise that is correlated w…
Efficient method to create superoscillations with generic target behavior
Barbara Šoda, Achim Kempf
We introduce a new numerically stable method for constructing superoscillatory wave forms inan arbitrary number of dimensions. The method allows the construction of superoscillator…
