Research

I am theoretical physicist that is interested in the foundations of quantum and gravitational phenomena. I received my bachelors degree from Federal Ceará University (UFC) where I began studying Quantum Field Theory and Randall-Sundrum models as an undergraduate. I earned my masters degree from Federal Fluminense University (UFF) working on modified gravity and Black Hole thermodynamics. I started my PhD at Rio de Janeiro State University (UERJ) researching inflationary models and reheating models of the early Universe but I changed focus when I was presented with the de Broglie-Bohm approach to quantum cosmology developed by professor Nelson Pinto-Neto from the Brazilian Center for Research in Physics (CBPF) at a conference in São Paulo in 2014. I was then advised by professor Santiago Bergliaffa and we started studying ways to develop predictions from the Pilot-wave theory that could set it apart from other approaches. My PhD thesis was focused on the Quantum Equilibrium Hypothesis proposed by Antony Valentini which states that the Born rule can represent a state of quantum equilibrium and possible deviations could be found in the early universe or in other extreme gravitational scenarios. I spent six months during my PhD working with prof. Valentini and his students at Clemson University in South Carolina. After my PhD I worked from 2019 to 2024 as a postdoc with prof. Pinto-Neto further developing the numerical analysis from my PhD thesis and extending my research to quantum cosmology and quantum gravity. In 2023 started a project aimed at finding ways to differentiate between quantum theories with tabletop quantum gravity experiments involving entanglement and decoherence that is still ongoing. In 2025 I was awarded a research fellowship from the Foundation for the Support of Scientific and Technological Development from Ceará (FUNCAP) in partnership with the National Council for Scientific and Technological Development (CNPq) to come to Iguatu in the backcountry of the northeast of Brazil, where I am continuing my previous projects with Pilot-wave theory as well as developing paralell research envolving other quantum gravity approaches, Black Holes, Wormholes and cosmic voids. Recently I have been interested in modes of cosmologically coupled Black Holes, applications of Pilot-wave theory to Black hole quantization and tabletop quantum gravity experiments.

Quantum relaxation in a system of harmonic oscillators with time-dependent coupling

In the context of the de Broglie–Bohm pilot-wave theory, numerical simulations for simple systems have shown that states that are initially out of quantum equilibrium—thus violating the Born rule—usually relax over time to the expected |ψ|² distribution on a coarse-grained level. We analyse the relaxation of non-equilibrium initial distributions for a system of coupled one-dimensional harmonic oscillators in which the coupling depends explicitly on time through numerical simulations, focusing on the influence of different parameters such as the number of modes, the coarse-graining length and the coupling constant. We show that in general the system studied here tends to equilibrium, but the relaxation can be retarded depending on the values of the parameters, particularly to the one related to the strength of the interaction. Possible implications on the detection of relic non-equilibrium systems are discussed.
