Cluster-projected matrix product state: Framework for engineering exact quantum many-body ground states in one and two dimensions

We propose a framework to design concurrently a frustration-free quantum many-body Hamiltonian and its numerically exact ground states on a sufficiently large finite-size cluster in one and two dimensions using an elementary matrix product state (MPS) representation. Our approach strategically choos...
