The Beyond Mean-Field (MF) Dynamics Of A Bent Dark Soliton (BDS) Embedded In A Two-Dimensional Repulsively Interacting Bose-Einstein Condensate Is Explored. We Examine The Case Of A Single BDS Comparing The MF Dynamics To A Correlated Approach, The Multi-Configuration Time-Dependent Hartree Method For Bosons. Dynamical Snaking Of This Bent Structure Is Observed, Signaling The Onset Of Fragmentation Which Becomes Significant During The Vortex Nucleation. In Contrast To The MF Approximation 'filling' Of The Vortex Core Is Observed, Leading In Turn To The Formation Of Filled-Core Vortices, Instead Of The MF Vortex-Antivortex Pairs. The Resulting Smearing Effect In The Density Is …

The Dynamics Of Dark-Bright (DB) Solitons Beyond The Mean-Field Approximation Is Investigated. We First Examine The Case Of A Single DB Soliton And Its Oscillations Within A Parabolic Trap. Subsequently, We Move To The Setting Of Collisions, Comparing The Mean-Field Approximation To That Involving Multiple Orbitals In Both The Dark And The Bright Component. Fragmentation Is Present And Significantly Affects The Dynamics, Especially In The Case Of Slower Solitons And In That Of Lower Atom Numbers. It Is Shown That The Presence Of Fragmentation Allows For Bipartite Entanglement Between The Distinguishable Species. Most Importantly The Interplay Between Fragmentation And Entanglement …
