# Effects of interaction imbalance in a strongly repulsive one-dimensional Bose gas. (arXiv:1802.02010v1 [cond-mat.quant-gas])

two-component strongly interacting Bose gas confined to an effectively

one-dimensional trapping potential. We describe the densities for each

component in the trap for different interaction and population imbalances. We

calculate the time evolution of the system and show that, for a certain ratio

of interactions, the minority population travels through the system as an

effective wave packet.
