Generalized $m$-body mean-field projections for classical simulation of $d$-dimensional Heisenberg-picture dynamics

Classical simulation of quantum many-body dynamics is challenged by the rapid growth of operator complexity, particularly in higher dimensions where tensor-network methods become increasingly demanding. We develop state-adapted Pauli-weight propagation based on generalized $m$-body mean-field projections, which compres...

State-adapted generalized mean-field projections for Pauli propagation of Heisenberg dynamics

The Heisenberg picture can make quantum many-body simulation efficient when evolved observables admit compact operator representation within low-dimensional structures. Conventional Pauli-string propagation and truncation techniques exploit this structure, but in coherent Hamiltonian dynamics their error control is oft...
