QCommute: a tool for symbolic computation of nested commutators in quantum many-body spin-1/2 systems
QCOMMUTE is a C++ tool for symbolically computing nested commutators between a Hamiltonian and local observables in quantum spin-1/2 systems on 1D, 2D, and 3D lattices. It provides a computational backend for Heisenberg-picture approaches to quantum dynamics by efficiently calculating time-dependent expectation values and autocorrelation functions.
