Effects of quantum fluctuations of the metric on a braneworld
C. A. S. Almeida, F. C. E. Lima
Adopting the premise that the expected value of the quantum fluctuating metric is linear, i.e., , we analyze the modified gravity theory induced by t…
Non-Hermitian fermions with effective mass
F. C. E. Lima, L. N. Monteiro, C. A. S. Almeida
In this work, we readdress the Dirac equation in the position-dependent mass (PDM) scenario. Here, one investigates the quantum dynamics of non-Hermitian fermionic particles with e…
Quantum information entropy of heavy mesons in the presence of a point-like defect
C. A. S. Almeida, C. O. Edet, F. C. E. Lima +2
Using Schrödinger's formalism, we investigate the quantum eigenstates of the heavy mesons trapped by a point-like defect and by Cornell's potential. One implements this defect to t…
Topological solitons in the sigma-cuscuton model
F. C. E. Lima, C. A. S. Almeida
Building a multi-field theory with canonical and non-canonical contributions, one studies the topological solitons of the O(3)-sigma model. We propose a model constituted by the O(…
