Description
We introduce and study the subsystem flow of local algebra inclusions comparing a subsystem's intrinsic modular evolution with the one inherited from a larger region in QFT and holography. By analytically continuing subsystem flow, we construct a class of inclusion parent Hamiltonians that allow the subsystem to leave the larger algebra. We show that in highly symmetric cases, these parent Hamiltonians are proportional to the global Hamiltonian. In holography, we propose that these parent Hamiltonians can be viewed as the generator of a bulk time evolution at local points in the bulk.
