Abstract
In this work, we investigate the nonequilibrium dynamics in a one-dimensional two-component anyon-Hubbard model, which can be mapped to an extended Bose-Hubbard ladder with density-dependent hopping phase and synthetic gauge flux. Through numerical simulations of few-particle dynamics and the analytical symmetry analysis without particle-number constraints, we reveal the asymmetric and imbalance transports with broken inversion symmetry and find two dynamical symmetries in the expansion dynamics unique to the two-component anyon-Hubbard chain. For any initial state that preserves both the time-reversal and inversion symmetries, the expansion is always dynamically symmetric under spatial inversion and component flip, when the sign of the anyonic statistics phase or the signs of both the gauge flux and interaction are changed. For vanishing Hubbard interaction, we show the dynamical suppression induced by both the statistics phase and the gauge flux. For finite Hubbard interaction, we further uncover tunable chiral-antichiral dynamics for two-component anyons under the gauge flux. We demonstrate that both chiral and antichiral dynamics can be exhibited and tuned by the statistics phase and the gauge flux. The dynamical phase regimes with respect to the chiral-antichiral dynamics for different system parameters are obtained. These findings highlight the dynamical phenomena arising from the interplay of anyonic exchange statistics, synthetic gauge fields, and Hubbard interactions in multicomponent anyons.
