Splitting frequency of the (2+1)-dimensional Duffin-Kemmer-Petiau oscillator in an external magnetic field
Ignacio S. Gomez, Esdras S. Santos, Olavo Abla
We revisit the (2+1)-dimensional DKP oscillator in an external magnetic field by means of 4x4 and 6x6 representations of the DKP field, thus obtaining several cases studied in the…
Morse potential in relativistic contexts from generalized momentum operator, Pekeris approximation revisited and mapping
Ignacio S. Gomez, Esdras S. Santos, Olavo Abla
In this work we explore a generalization of the Dirac and Klein-Gordon (KG) oscillators, provided with a deformed linear momentum inspired in nonextensive statistics, that gives pl…
Lorentz-violating extension of the spin-one Duffin-Kemmer-Petiau equation
H. Belich, E. Passos, M. de Montigny +1
We investigate the breaking of Lorentz symmetry caused by the inclusion of an external four-vector via a Chern-Simons-like term in the Duffin-Kemmer-Petiau Lagrangian for massless…
Massless Dirac-like fermions under external fields: a nonminimal coupling approach
E. Marcelino, E. S. Santos, R. Rivelino
We investigate the unusual properties of quasirelativistic massless fermions under a magnetic or electric field by means of nonminimal couplings. Within this approach, the spin-orb…
Maximum Entanglement in Squeezed Boson and Fermion States
F. C. Khanna, J. M. C. Malbouisson, A. E. Santana +1
A class of squeezed boson and fermion states is studied with particular emphasis on the nature of entanglement. We first investigate the case of bosons, considering two-mode squeez…
General Formula for N-point One-loop Feynman Integrals
Alfredo T. Suzuki, Esdras S. Santos, Alexandre G. M. Schmidt
The negative dimensional integration method (NDIM) is a technique where several difficulties concerning loop integration can be overcome. From usual covariant gauges to complicated…
