Bosonic systems live in an infinite-dimensional space, and in order to be able to describe them one usually reduces it to an effective finite dimension or constrain the dynamics in some way, but it is not fully understood whether this captures all the physics at play. Here, the authors fill this gap showing that such representations can successfully and rigorously approximate bosonic physics.
