Three-dimensional Dirac oscillator in a thermal bath
M. H. Pacheco, R. V. Maluf, C. A. S. Almeida +1
The thermal properties of the three-dimensional Dirac oscillator are considered. The canonical partition function is determined, and the high-temperature limit is assessed. The deg…
One-dimensional Dirac oscillator in a thermal bath
M. H. Pacheco, R. R. Landim, C. A. S. Almeida
We analyze the one-dimensional Dirac oscillator in a thermal bath. We found that the heat capacity is two times greater than the heat capacity of the one-dimensional harmonic oscil…
Treating some solid state problems with the Dirac equation
R. Renan, M. H. Pacheco, C. A. S. Almeida
The ambiguity involved in the definition of effective-mass Hamiltonians for nonrelativistic models is resolved using the Dirac equation. The multistep approximation is extended for…
