In a dipole-conserving Bose-Hubbard chain, weak Hilbert-space fragmentation permits thermalization at weak interactions but yields nonergodicity at strong interactions, shown via analytical bounds on frozen states and exact diagonalization of entanglement, relaxation, and level statistics.

Weak Fragmentation and Thermalization in a Dipole-Conserving Bose-Hubbard Chain
In a dipole-conserving Bose-Hubbard chain, weak Hilbert-space fragmentation permits thermalization at weak interactions but yields nonergodicity at strong interactions, shown via analytical bounds on frozen states and exact diagonalization of entanglement, relaxation, and level statistics.
