De Castro, A. S. [UNESP]Dutra, Alvaro de Souza [UNESP]2014-05-272014-05-272003-05-01Physical Review A - Atomic, Molecular, and Optical Physics, v. 67, n. 5, p. 541011-541013, 2003.1050-2947http://hdl.handle.net/11449/67273The construction of two classes of exact solutions for the most general time-dependent Dirac Hamiltonian in 1+1 dimensions was discussed. The extension of solutions by introduction of a time-dependent mass was elaborated. The possibility of existence of a generalized Lewis-Riesenfeld invariant connected with such solutions was also analyzed.541011-541013engFunctionsHamiltoniansMathematical transformationsQuantum theoryWave equationsWave functionsAtomic physicsArtigo10.1103/PhysRevA.67.054101WOS:000183298800100Acesso aberto2-s2.0-00387833102-s2.0-0038783310.pdf58117000831954806314084638411003
