Influence of the Electron's Anomalous Magnetic Dipole Moment on High-Atomic-Number Atoms
C. A. S. Almeida, J. Auto-Neto
Super-heavy atoms () are usually studied in the context of the so-called ``Quantum Electrodynamics of Strong Fields''. In this theory the problem of the singularity in the…
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…
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 generali…
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…
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…
Kinks and double-kinks in generalized -and -models
F. C. E. Lima, R. Casana, C. A. S. Almeida
Examining the and models within a two-dimensional framework in the flat spacetime and embracing a theory with unconventional kinetic terms, one investigates the e…
