Phys. Rev. A 61, 054101 (2000) [3 pages]Wave functions for a Dirac particle in a time-dependent potentialReceived 29 June 1999; published 30 March 2000 We have presented a simple treatment to the problem of finding the wave functions for Dirac particles in a time-dependent potential. The treatment is based on the use of Lewis-Riesenfield invariant method [J. Math Phys. 10, 1458 (1969)]. Here we construct a linear time-dependent invariant which allows us to obtain the wave function of the system. © 2000 The American Physical Society URL:
