Entanglement in bipartite systems with symmetry: coupled chaotic kicked Bose-Hubbard systems
We investigate the average eigenstate entanglement in a bipartite many-body system which exhibits a breaking of two local conservation laws into a global conserved quantity. Such a setting is realized by the particle number conservation in Bose-Hubbard systems. We devise a corresponding random matrix model which captur...
