Velocity effects slightly mitigating the quantumness degradation of an Unruh-DeWitt detector
P. H. M. Barros, Shu-Min Wu, C. A. S. Almeida +1
In this work, we investigate the velocity effects on information degradation due to the Unruh effect in accelerated quantum systems (with finite interaction time). We consider a de…

Mitigating the information degradation in a massive Unruh-DeWitt theory
P. H. M. Barros, F. C. E. Lima, C. A. S. Almeida +1
We investigated the influence of the massive scalar field on the information degradation concerning the Unruh-DeWitt (UDW) detectors. In this conjecture, we adopted a system with a…

Dispersive vacuum as a decoherence amplifier of an Unruh-DeWitt detector
Pedro H. M. Barros, Helder A. S. Costa
Recently, interest has been growing in studies on discrete or "pixelated" space-time that, through modifications in the dispersion relation, can treat the vacuum as a dispersive me…
