Chaotic dynamics of Bose-Einstein condensates in a tilted optical lattice
C. Selvaraju, S. Sabari, O. T. Lekeufack +2
This study investigates the emergence of chaotic dynamics in Bose-Einstein condensates (BECs) subjected to both alternating (AC) and constant (DC) components of the interaction str…

The effects of elastic and inelastic collisions in two- and three-body interactions on the stability of 3D Bose-Einstein condensates
R. Sasireka, O. T. Lekeufack, S. Sabari +1
In this paper, we study the stability of three-dimensional Bose-Einstein condensates of finite temperatures at which both elastic and inelastic collisions are taken into account. T…

Role of higher-order interactions on the modulational instability of Bose-Einstein condensate trapped in a periodic optical lattice
S. Sabari, OT. Lekeufack, SB. Yamgoue +2
In this paper, we investigate the impact of higher-order interactions on the modulational instability (MI) of Bose-Einstein Condensates (BECs) immersed in an optical lattice potent…
