Gravitational decoherence of a composite particle: the interplay between gravitons and a classical Newtonian potential
Thiago H. Moreira, Lucas Chibebe Céleri
The fact that gravitational environments cannot be shielded (since gravity is universal) makes them of great theoretical interest to decoherence mechanisms and to the quantum-to-cl…
Decoherence and entropy production due to quantum fluctuations of spacetime
Thiago H. Moreira
The intersection between quantum mechanics and gravitational physics has been providing challenging puzzles for decades. In this thesis, we study the dynamics of an open quantum sy…
Dynamical Casimir effect under the action of gravitational waves
Gustavo de Oliveira, Thiago Henrique Moreira, Lucas Chibebe Céleri
Several nontrivial phenomena emerge when a quantum field is subjected to dynamical perturbations, with prominent examples including the Hawking and Unruh effects, as well as the dy…
Graviton induced decoherence of a composite particle
T. H. Moreira, L. C. Céleri
We consider a composite particle, whose internal degrees of freedom are described by quantum mechanics, interacting with the quantum gravitational field in the linear approximation…
Entropy production due to spacetime fluctuations
Thiago H Moreira, Lucas C. Céleri
Understanding the quantum nature of the gravitational field is undoubtedly one of the greatest challenges in theoretical physics. Despite significant progress, a complete and consi…
