Research

II am a physicist with experience in gravitation and cosmology, quantum field theory and quantum foundations. I earned my PhD at Rio de Janeiro State University (UERJ/2019) with a sandwich period at Clemson University (USA) working with Antony Valentini. I spent 5 years as a postdoc at the Brazilian Center for Research in Physics (CBPF/2019 - 2024) and am now a postodc at Ceará State University (UECE/2024 - ). My main research is focused on the Pilot-Wave Theory (or de Broglie-Bohm Theory) and the Quantum Equilibrium Hypothesis. I apply this theory to cosmology, black hole physics and other scenarios where the quantum and gravitational realms colide. I have also worked on multiple other topics in alternative gravity theories and quantum gravity more broadly. From nanoscale gravitational measurements, to entanglement an decoherence experiments and going up to the astrophysical and cosmological scales, the goal is to get a comprehensive understanding of what we need to bridge the gap between the foundations of Quantum Mechanics and General Relativity.

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.
