DESCRIPTION:Abstract:In the recent experiment by S. E. Pollack et. al.\, P
 RA 81\, 053627 (2010)\, a Bose-Einstein condensate of $^7$Li has been exci
 ted by a harmonic modulation of the atomic s-wave scattering length via Fe
 shbach resonance. Combining an analytical perturbative approach with numer
 ical simulations we analyze the resulting nonlinear dynamics of the system
  on the mean-field Gross-Pitaevskii level. Our detailed results show the p
 resence of higher harmonics and mode coupling. Most importantly\, we also 
 find significant shifts of the col- lective modes frequencies in the reson
 ance region which are due to the nonlinearity of the system dynamics. Fina
 lly\, we indicate how these frequency shifts could be measured in a future
  experiment.\n\nhttps://events.saifa.rs/event/110/
