| Resumen en inglés | We adapt the nonlinear stimulated Raman exact passage technique first proposed by Dorier et al. [Phys. Rev. Lett. 119 (2017) 243902] to fractional population transfer in Λ configurations and extend it to nonlinear N-pod systems. We use the nonlinear fractional stimulated Raman adiabatic passage technique in a Λ system and indicate that the nonlinear fractional stimulated Raman exact passage technique can guide the dynamics of the system as efficiently as a nonlinear fractional stimulated Raman adiabatic passage technique but with considerably smaller Rabi frequency amplitudes. We also use the nonlinear fractional stimulated Raman exact passage technique in fractional creation of ground molecular Bose-Einstein condensates from atomic Bose-Einstein condensates and show that this technique is robust against moderate variations in peak Rabi frequencies and in time delay between the pulses |
