The Complexity of Translationally-Invariant Low-Dimensional Spin Lattices in 3D
Johannes Bausch, Stephen Piddock
In this paper, we consider spin systems in three spatial dimensions, and prove that the local Hamiltonian problem for 3D lattices with face-centered cubic unit cells, 4-local trans…

Universal Quantum Hamiltonians
Toby Cubitt, Ashley Montanaro, Stephen Piddock
Quantum many-body systems exhibit an extremely diverse range of phases and physical phenomena. Here, we prove that the entire physics of any other quantum many-body system is repli…
