Full Professor at the Institute for Theoretical Physics at the Sao Paulo State University, CNPq senior researcher and member at the Academy of Sciences of the Sao Paulo State. Works on the interface between gravity and quantum mechanics. He had several works highlighted in forums such as Science, Nature, and Physical Review Focus. Several of his former undergraduate and MSc research students were later accepted into leading Universities such as Cambridge (UK), Perimeter Institute (Canada), Maryland (USA), among others. Among his former DSc students, some were awarded by the Brazilian Physical Society and Coordination for the Improvement of Higher Education Personnel with prizes of Best Thesis in Physics and several of them develop successful independent careers with works highlighted by societies such as the American Physical Society (APS). In 2008, he was recognized by the same APS as Outstanding Referee. (Source: Lattes Curriculum)

On the one hand, quantum field theory in curved spacetimes (QFTCS) is the best formalism we have for studying quantum effects in predefined spacetimes at energies low enough such that quantum gravitational degrees of freedom -- whatever they are -- are not excited. On the other hand, QFTCS is not reliable, in general, to explain how quantum systems impact our present space-time concept: a…
The semiclassical gravity or quantum field theory in curved spacetimes has been shown to be efficient to analyze quantum processes in energy scales below the Planck one, where quantum gravity degrees of freedom (whatever they are) are not excited. In this project we propose to investigate various quantum aspects around relativistic stars, black holes, and accelerated reference frames, an…
The search for the fundamental theory which describes Nature at the Planck scale still seems to be far from being accomplished. Notwithstanding, whatever this theory turns out to be, it should contain Quantum Field Theory in the low-energy limit. In the case that matter fields are under the influence of strong gravitational fields, the standard formalism should be extended to take into ac…

Due to the impracticalities of testing the effects at the intersection of general relativity and quantum mechanics, particularly given the scale required for such experiments, it is useful to turn to analog models. These models, which are more controllable systems, mimic the behavior of gravity. One such phenomenon, that remains experimentally unobserved at this interface, is the Unruh ef…
The grand goal behind this project is to go a step forward concerning interpreting phenomena from the point of view of uniformly accelerated observers in terms of the Unruh effect to mount more shreds of evidence that the Unruh effect is necessary to keep the consistency of quantum field theory. Ultimately, we aim to strengthen the collaboration of our group with experimentalists able to …
The grand goal behind this project is to proceed a step forward concerning Quantum Field Theory in Curved Spacetimes (QFTCS). QFTCS formalism provides quite reliable results provided we stay below the Planck scale and is used in a predetermined background spacetime. Yet, the backreaction of the quantum fields on the spacetime itself is much more difficult to assess. We aim to look for ins…
Hawking's semi-classical description of black hole evaporation has been challenged because observers at future infinity have access to less information than those at past infinity, seemingly in conflict with the canons of quantum mechanics according to which the evolution is unitary. In this project, we intend to argue that, far from paradoxical, the loss of information is a natural conse…
Several effects of Quantum Field Theory (QFT) can be understood in terms of the physics of a few harmonic oscillators. At first, we intend to create a more acute intuition about this important theory that describes from the quantum behavior of quasi-particles in condensed matter to the elementary constituents of matter. In this step, we will also discuss the intrinsic characteristics of Q…
In this IC project, we intend to revisit the rules of mass superselection of non-relativistic quantum mechanics. This result taken alone seems to lead to contradictions with the non-relativistic limit of relativistic quantum mechanics. Recent results suggest that non-relativistic quantum mechanics must be endowed with the information that energy has weight, E = m c ^ 2, if it is expected …
