Emergent magnetic order in the antiferromagnetic Kitaev model with a [111] field
Will Holdhusen, Daniel Huerga, Gerardo Ortiz
The Kitaev spin liquid, stabilized as the ground state of the Kitaev honeycomb model, is a paradigmatic example of a topological quantum spin liquid. The fate of the…
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…
Composite fermion-boson mapping for fermionic lattice models
Jinmo Zhao, Carlos A. Jimenez-Hoyos, Gustavo E. Scuseria +4
We present a mapping of elementary fermion operators onto a quadratic form of composite fermionic and bosonic operators. The mapping is an exact isomorphism as long as the physical…
Chiral phases of two-dimensional hard-core bosons with frustrated ring-exchange
Daniel Huerga, Jorge Dukelsky, Nicolas Laflorencie +1
We study the zero temperature phase diagram of two-dimensional hard-core bosons on a square lattice with nearest neighbour and plaquette (ring-exchange) hoppings, at arbitrary dens…
