The fate of Galilean relativity in minimal-length theories
Pasquale Bosso, Giuseppe Fabiano, Domenico Frattulillo +1
A number of arguments at the interplay of general relativity and quantum theory suggest an operational limit to spatial resolution, conventionally modelled as a generalized uncerta…
Bell nonlocality in maximal-length quantum mechanics
Pasquale Bosso, Fabrizio Illuminati, Luciano Petruzziello +1
In this paper, we investigate the consequences of maximal length as well as minimal momentum scales on nonlocal correlations shared by two parties of a bipartite quantum system. To…
Quantum-spacetime effects on nonrelativistic Schrödinger evolution
Fabian Wagner, Gislaine Varão, Iarley P. Lobo +1
The last three decades have witnessed the surge of quantum gravity phenomenology in the ultraviolet regime as exemplified by the Planck-scale accuracy of time-delay measurements fr…
30 years in: Quo vadis generalized uncertainty principle?
Pasquale Bosso, Giuseppe Gaetano Luciano, Luciano Petruzziello +1
According to a number of arguments in quantum gravity, both model-dependent and model-independent, Heisenberg's uncertainty principle is modified when approaching the Planck scale.…
The minimal length: a cut-off in disguise?
Pasquale Bosso, Luciano Petruzziello, Fabian Wagner
The minimal-length paradigm, a possible implication of quantum gravity at low energies, is commonly understood as a phenomenological modification of Heisenberg's uncertainty relati…
Shift-symmetric Horndeski gravity in the asymptotic-safety paradigm
Astrid Eichhorn, Rafael R. Lino dos Santos, Fabian Wagner
Horndeski gravity is a popular contender for a phenomenological model of dynamical dark energy, and as such subject to observational constraints. In this work, we ask whether Hornd…
An algorithmic approach to finding canonical differential equations for elliptic Feynman integrals
Christoph Dlapa, Johannes M. Henn, Fabian J. Wagner
In recent years, differential equations have become the method of choice to compute multi-loop Feynman integrals. Whenever they can be cast into canonical form, their solution in t…
Modified uncertainty relations from classical and quantum gravity
Fabian Wagner
A good hundred years after the necessity for a quantum theory of gravity was acknowledged by Albert Einstein, the search for it continues to be an ongoing endeavour. Nevertheless,…
Momentum gauge fields from curved momentum space through Kaluza-Klein reduction
Eduardo Guendelman, Fabian Wagner
In this work we investigate the relation between curved momentum space and momentum-dependent gauge fields. While the former is a classic idea that has been shown to be tied to min…
Curved momentum space equivalent to the linear and quadratic Generalized Uncertainty Principle
Fabian Wagner
In this work, we deepen the correspondence between Generalized Uncertainty Principles (GUPs) and quantum dynamics on curved momentum space. In particular, we investigate the linear…
Spin operator, Bell nonlocality and Tsirelson bound in quantum-gravity induced minimal-length quantum mechanics
Pasquale Bosso, Luciano Petruzziello, Fabian Wagner +1
Different approaches to quantum gravity converge in predicting the existence of a minimal scale of length. This raises the fundamental question as to whether and how an intrinsic l…
The minimal length is physical
Pasquale Bosso, Luciano Petruzziello, Fabian Wagner
In this paper, we clarify a foundational loose end affecting the phenomenological approach to quantum gravity centered around the generalization of Heisenberg uncertainty principle…
Reinterpreting deformed Heisenberg algebras
Fabian Wagner
Minimal and maximal uncertainties of position measurements are widely considered possible hallmarks of low-energy quantum as well as classical gravity. While General Relativity des…
A New Guest in the Third Quantized Multiverse
Samuel Barroso Bellido, Fabian Wagner
In the present article we point out a conceptual issue of the Third Quantization formalism for Canonical Quantum Gravity. Based on earlier results on interuniversal entanglement, t…
Towards quantum Mechanics on the curved cotangent bundle
Fabian Wagner
The minimal-length paradigm is a cornerstone of quantum gravity phenomenology. Recently, it has been demonstrated that minimal-length quantum mechanics can alternatively be describ…
Relativistic Extended Uncertainty Principle from Spacetime Curvature
Fabian Wagner
The investigations presented in this study are directed at relativistic modifications of the uncertainty relation derived from the curvature of the background spacetime. These find…
Generalized uncertainty principle or curved momentum space?
Fabian Wagner
The concept of minimum length, widely accepted as a low-energy effect of quantum gravity, manifests itself in quantum mechanics through generalized uncertainty principles. Curved m…
The ensemble Kalman filter for rare event estimation
Fabian Wagner, Iason Papaioannou, Elisabeth Ullmann
We present a novel sampling-based method for estimating probabilities of rare or failure events. Our approach is founded on the Ensemble Kalman filter (EnKF) for inverse problems.…
Gravitationally induced uncertainty relations in curved backgrounds
Luciano Petruzziello, Fabian Wagner
This paper aims at investigating the influence of space-time curvature on the uncertainty relation. In particular, relying on previous findings, we assume the quantum wave function…
Error analysis for probabilities of rare events with approximate models
Fabian Wagner, Jonas Latz, Iason Papaioannou +1
The estimation of the probability of rare events is an important task in reliability and risk assessment. We consider failure events that are expressed in terms of a limit-state fu…
Asymptotic Generalized Extended Uncertainty Principle
Mariusz P. Dabrowski, Fabian Wagner
We present a formalism which allows for the perturbative derivation of the Extended Uncertainty Principle (EUP) for arbitrary spatial curvature models and observers. Entering the r…

Extended Uncertainty Principle for Rindler and cosmological horizons
Mariusz P. Dabrowski, Fabian Wagner
We find exact formulas for the Extended Uncertainty Principle (EUP) for the Rindler and Friedmann horizons and show that they can be expanded to obtain asymptotic forms known from…
