Quantum gravity inspired nonlocal quantum dynamics preserving the classical limit
Marzena Ciszak, Alessio Belenchia, Antonello Ortolan +1
Several approaches to quantum gravity lead to nonlocal modifications of fields' dynamics. This, in turn, can give rise to nonlocal modifications of quantum mechanics at non-relativ…
Non-linear media in weakly curved spacetime: optical solitons and probe pulses for gravimetry
Alessio Belenchia, Felix Spengler, Dennis Rätzel +1
That light propagating in a gravitational field gets frequency-shifted is one of the basic consequences of any metric theory of gravity rooted in the equivalence principle. At the…
Optical solitons in curved spacetime
Felix Spengler, Alessio Belenchia, Dennis Rätzel +1
Light propagation in curved spacetime is at the basis of some of the most stringent tests of Einstein's general relativity. At the same time, light propagation in media is at the b…
Influence of cosmological expansion in local experiments
Felix Spengler, Alessio Belenchia, Dennis Rätzel +1
Whether the cosmological expansion can influence the local dynamics, below the galaxy clusters scale, has been the subject of intense investigations in the past three decades. In t…
Tests of Quantum Gravity-Induced Non-Locality: Hamiltonian formulation of a non-local harmonic oscillator
Alessio Belenchia, Dionigi M. T. Benincasa, Francesco Marin +4
Motivated by the development of on-going optomechanical experiments aimed at constraining non-local effects inspired by some quantum gravity scenarios, the Hamiltonian formulation…
On the Entanglement Entropy of Quantum Fields in Causal Sets
Alessio Belenchia, Dionigi M. T. Benincasa, Marco Letizia +1
In order to understand the detailed mechanism by which a fundamental discreteness can provide a finite entanglement entropy, we consider the entanglement entropy of two classes of…
