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…
Nonlinear particle detectors across the Rindler firewall
Matheus H. Zambianco, Eduardo Martín-Martínez
We investigate Unruh-DeWitt detectors coupled to composite observables of a quantum scalar field, including quadratic coupling to the field momentum and coupling to the local energ…
Ultraviolet structure of entanglement harvesting from energy density and other quadratic couplings
Matheus H. Zambianco, Boris Ragula, Eduardo Martín-Martínez
We study entanglement harvesting with particle detectors coupled to the renormalized energy density of a massless scalar field. Our analysis identifies the distributional mechanism…
Cosmological Expansion Induces Interference Between Communication and Entanglement Harvesting
Matheus H. Zambianco, Adam Teixidó-Bonfill, Eduardo Martín-Martínez
We investigate the interplay between genuine entanglement harvesting and communication mediated correlations for local particle detectors in expanding cosmological spacetimes. Focu…
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…
Finite-size clocks in quantum field theory and the twin paradox
Matheus H. Zambianco, T. Rick Perche
Vacuum fluctuations in quantum field theory impose fundamental limitations on our ability to measure time at arbitrarily short scales. To investigate the impact of universal quantu…
