Entanglement in gapless resonating valence bond states
Jean-Marie Stéphan, Hyejin Ju, Paul Fendley +1
We study resonating-valence-bond (RVB) states on the square lattice of spins and of dimers, as well as SU(N)-invariant states that interpolate between the two. These states are gro…

Bridging lattice-scale physics and continuum field theory with quantum Monte Carlo simulations
Ribhu K. Kaul, Roger G. Melko, Anders W. Sandvik
We discuss designer Hamiltonians---lattice models tailored to be free from sign problems ("de-signed") when simulated with quantum Monte Carlo methods but which still host complex…
