Finite Speed of Quantum Information in Models of Interacting Bosons at Finite Density
We prove that quantum information propagates with a finite velocity in any model of interacting bosons whose (possibly time-dependent) Hamiltonian contains spatially local single-boson hopping terms along with arbitrary local density-dependent interactions. More precisely, with the density matrix ρ∝...
