Dynamics of discrete spacetimes with Quantum-enhanced Markov Chain Monte Carlo
Stuart Ferguson, Arad Nasiri, Petros Wallden
Quantum algorithms offer the potential for significant computational advantages; however, in many cases, it remains unclear how these advantages can be practically realized. Causal…
Covariant diffusion and drift of the stochastic GW background with LISA
Giorgio Mentasti, Arad Nasiri
We study the covariant diffusion and drift of massless particles on the light cone within the context of quantum gravity phenomenology. Unlike modified dispersion relations that vi…
Stochastic dark matter: Covariant Brownian motion from Planckian discreteness
Emma Albertini, Arad Nasiri, Emanuele Panella
Quantum gravity has long remained elusive from an observational standpoint. Developing effective cosmological models motivated by the fundamental aspects of quantum gravity is cruc…
Aspects of Everpresent (II): Cosmological Tests of Current Models
Santanu Das, Arad Nasiri, Yasaman K. Yazdi
This paper investigates Everpresent , a stochastic dark energy model motivated by causal set theory and unimodular gravity, and confronts it with two key observational data set…
