Title: | Trapping neutral fermions with kink-like potentials | Authors: | Castro, Antonio S. de Hott, Marcelo |
Issue Date: | 2006 | Citation: | Physics Letters A. 351:6 (2006) 379-383 | Abstract: | The intrinsically relativistic problem of neutral fermions subject to kink-like potentials (~tanh[gamma]x) is investigated and the exact bound-state solutions are found. Apart from the lonely hump solutions for E=±mc2, the problem is mapped into the exactly solvable Sturm-Liouville problem with a modified Pöschl-Teller potential. An apparent paradox concerning the uncertainty principle is solved by resorting to the concepts of effective mass and effective Compton wavelength. | URI: | https://hdl.handle.net/10316/4413 | DOI: | 10.1016/j.physleta.2005.11.033 | Rights: | openAccess |
