Soft breaking of the symmetry in the theory
F. C. E. Lima, C. A. S. Almeida
We consider a two-dimensional scalar field theory that modifies the standard model by introducing a smooth breaking of translational invariance through a hyperbolic generaliz…

Divide-and-Conquer Simulation of Open Quantum Systems
Thiago Melo D. Azevedo, Caio Almeida, Pedro Linck +2
One of the promises of quantum computing is to simulate physical systems efficiently. However, the simulation of open quantum systems - where interactions with the environment play…

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…
