Translation-Invariant Parent Hamiltonians of Valence Bond Crystals
Daniel Huerga, Andres Greco, Claudio Gazza +1
We present a general method to construct translation-invariant and SU(2) symmetric antiferromagnetic parent Hamiltonians of valence bond crystals (VBC). The method is based on a ca…

Staircase of crystal phases of hard-core bosons on the Kagome lattice
Daniel Huerga, Sylvain Capponi, Jorge Dukelsky +1
We study the quantum phase diagram of a system of hard-core bosons on the Kagome lattice with nearest-neighbor repulsive interactions, for arbitrary densities, by means of the hier…
