Unifying Kitaev magnets, kagomé dimer models, and ruby Rydberg spin liquids

R Verresen, A Vishwanath - Physical Review X, 2022 - APS
The exploration of quantum spin liquids (QSLs) has been guided by different approaches
including the resonating valence bond (RVB) picture, deconfined lattice gauge theories, and …

Entanglement order parameters and critical behavior for topological phase transitions and beyond

M Iqbal, N Schuch - Physical Review X, 2021 - APS
Order parameters are key to our understanding of phases of matter. Not only do they allow
one to classify phases, but they also enable the study of phase transitions through their …

Locality optimization for parent Hamiltonians of tensor networks

G Giudici, JI Cirac, N Schuch - Physical Review B, 2022 - APS
Tensor network states form a powerful framework for both the analytical and numerical study
of strongly correlated phases. Vital to their analytical utility is that they appear as the exact …

Vison condensation and spinon confinement in a kagome-lattice spin liquid: A numerical study of a quantum dimer model

K Hwang - Physical Review B, 2024 - APS
Quantum spin liquids are exotic many-body states featured with long-range entanglement
and fractional anyon quasiparticles. Quantum phase transitions of spin liquids are …

Gapped spin liquid in the breathing kagome Heisenberg antiferromagnet

M Iqbal, D Poilblanc, N Schuch - Physical Review B, 2020 - APS
We investigate the spin-1/2 Heisenberg antiferromagnet on a kagome lattice with breathing
anisotropy (ie, with weak and strong triangular units), constructing an improved simplex …

Quantum trimer models and topological SU (3) spin liquids on the kagome lattice

S Jandura, M Iqbal, N Schuch - Physical Review Research, 2020 - APS
We construct and study quantum trimer models and resonating SU (3)-singlet models on the
kagome lattice, which generalize quantum dimer models and the resonating valence bond …
