Bloch oscillations emerge in continuum interacting quantum gases via strong interactions and are captured by generalized hydrodynamics in the Yang-Gaudin model, with finite-density renormalization from bound states.
Non-Hermitian bosonic chains with symmetric hopping can host k-local charges for selected k only, providing counterexamples to all-or-nothing integrability and showing the Grabowski-Mathieu 3-local test is not universal.
Tuning quadrupolar interactions in a spin-1 chain reveals a conserved quantity at the SU(3) point that limits accessible states and alters quench dynamics of magnetization, entanglement, and correlations.
Simulations identify distinct regimes in 1D Bose-Josephson dynamics: coherent oscillations, imbalance-driven dephasing with collapse-revival, equilibration with fragmentation, and strong-interaction dynamical freezing with suppressed tunneling.

Generalized Hydrodynamics of Bloch Oscillations in the Absence of a Lattice

Violating the All-or-Nothing Picture of Local Charges in Non-Hermitian Bosonic Chains
Non-Hermitian bosonic chains with symmetric hopping can host k-local charges for selected k only, providing counterexamples to all-or-nothing integrability and showing the Grabowski-Mathieu 3-local test is not universal.

Quantum quenches in a spin-1 chain with tunable symmetry
Tuning quadrupolar interactions in a spin-1 chain reveals a conserved quantity at the SU(3) point that limits accessible states and alters quench dynamics of magnetization, entanglement, and correlations.

Dynamics of one-dimensional Bose-Josephson Junction in a Box Trap: From Coherent Oscillations to Many-Body Dephasing and Dynamical Freezing
Simulations identify distinct regimes in 1D Bose-Josephson dynamics: coherent oscillations, imbalance-driven dephasing with collapse-revival, equilibration with fragmentation, and strong-interaction dynamical freezing with suppressed tunneling.
