  Here we examine the generation of Twist and Turn (TNT) Squeezing in a large
atom-number Bose-Einstein Condensate for the purposes of generating
quantum-enhanced states for atom interferometry. Unlike previous analysis, we
examine situations where the multi-mode dynamics is significant, and cannot be
captured by a simple single-mode model. We find that in some regimes, with
careful choice of the rotation parameter, we can still obtain squeezing much
more rapidly than via one-axis twisting (OAT).
