Spectral properties of the 2D magnetic Weyl-Dirac operator with a short-range potential
M. B. Alves, O. M. Del Cima, D. H. T. Franco +1
This paper is devoted to the study of the spectral properties of the Weyl-Dirac or massless Dirac operators, describing the behavior of quantum quasi-particles in dimension 2 in a…
Ostwald ripening for air bubbles and decompression illness: phenomenological aspects in diving
O. M. Del Cima, C. M. Rocha, A. V. N. C. Teixeira +1
The Ostwald ripening phenomenon for gas bubbles in a liquid consists mainly in gas transfer from smaller bubbles to larger bubbles. An experiment was carried out in which the Ostwa…
Magnetic shielding of quantum entanglement states
O. M. Del Cima, D. H. T. Franco, M. M. Silva
The measure of quantum entanglement is determined for any dimer, either ferromagnetic or antiferromagnetic, spin-1/2 Heisenberg systems in the presence of external magnetic field.…
No radiative generation of Chern-Simons-like term in Lorentz-violating QED: dealing with IR divergences
O. M. Del Cima, D. H. T. Franco, O. Piguet
The issue intensively claimed in the literature on the generation of a CPT-odd and Lorentz violating Chern-Simons-like term by radiative corrections owing to a CPT violating intera…
The Jackiw-Pi model: classical theory
O. M. Del Cima
The massive even-parity non-Abelian gauge model in three space-time dimensions proposed by Jackiw and Pi is studied at the tree-level. The propagators are computed and the spectrum…
No parity anomaly in massless QED3: a BPHZL approach
Oswaldo M. Del Cima, Daniel H. T. Franco, Olivier Piguet +1
In this letter we call into question the perturbatively parity breakdown at 1-loop for the massless QED_3 frequently claimed in the literature. As long as perturbative quantum fiel…
