Angular momentum expectation value per particle [\(\frac{1}{N}\langle \Psi \vert \hat{L}_Z \vert \Psi \rangle\)] after rotation quenches in the elongated trap. The analysis is performed for (a) small, (b) intermediate, and (c) large rotation quenches. The mean-field results employing one time-adaptive orbital (\(M = 1\)) are illustrated in black, and the corresponding many-body results utilizing \(M = 8\) time-adaptive orbitals are shown in red. The insets provide the Fourier transform of the many-body angular momentum over time, revealing the number of rotational modes involved in the dynamics. All quantities shown are dimensionless.
