Nonlocal Scalar Quantum Field Theory from Causal Sets
Alessio Belenchia, Dionigi M. T. Benincasa, Stefano Liberati
We study a non-local scalar quantum field theory in flat spacetime derived from the dynamics of a scalar field on a causal set. We show that this non-local QFT contains a continuum…

Emergent gravitational dynamics in relativistic Bose--Einstein condensate
Alessio Belenchia, Stefano Liberati, Arif Mohd
Analogue models of gravity have played a pivotal role in the past years by providing a test bench for many open issues in quantum field theory in curved spacetime such as the robus…
