A polynomial time algorithm for the ground state of one-dimensional gapped local Hamiltonians

The density matrix renormalization group method has been extensively used to study the ground state of 1D many-body systems since its introduction two decades ago. In spite of its wide use, this heuristic method is known to fail in certain cases and no certifiably correct implementation is known, le...
