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…
Variational Quantum Simulation of Valence-Bond Solids
Daniel Huerga
We introduce a hybrid quantum-classical variational algorithm to simulate ground-state phase diagrams of frustrated quantum spin models in the thermodynamic limit. The method is ba…
Digital-analog quantum simulation of fermionic models
Lucas C. Céleri, Daniel Huerga, Francisco Albarrán-Arriagada +3
Simulating quantum many-body systems is a highly demanding task since the required resources grow exponentially with the dimension of the system. In the case of fermionic systems,…
Random access codes via quantum contextual redundancy
Giancarlo Gatti, Daniel Huerga, Enrique Solano +1
We propose a protocol to encode classical bits in the measurement statistics of many-body Pauli observables, leveraging quantum correlations for a random access code. Measurement c…
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…
Density-dependent synthetic magnetism for ultracold atoms in optical lattices
Sebastian Greschner, Daniel Huerga, Gaoyong Sun +2
Raman-assisted hopping can allow for the creation of density-dependent synthetic magnetism for cold neutral gases in optical lattices. We show that the density-dependent fields lea…
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…
Composite Boson Mapping for Lattice Boson Systems
Daniel Huerga, Jorge Dukelsky, Gustavo E. Scuseria
We present a canonical mapping transforming physical boson operators into quadratic products of cluster composite bosons that preserves matrix elements of operators when a physical…
