Ground states of unfrustrated spin Hamiltonians satisfy an area law
Niel de Beaudrap, Tobias J. Osborne, Jens Eisert
We show that ground states of unfrustrated quantum spin-1/2 systems on general lattices satisfy an entanglement area law, provided that the Hamiltonian can be decomposed into neare…

Solving frustration-free spin systems
N. de Beaudrap, M. Ohliger, T. J. Osborne +1
We identify a large class of quantum many-body systems that can be solved exactly: natural frustration-free spin-1/2 nearest-neighbor Hamiltonians on arbitrary lattices. We show th…
