The spin-orbital Kitaev model: from kagome spin ice to classical fractons
Weslei B. Fontana, Fabrizio G. Oliviero, Rodrigo G. Pereira +1
We study an exactly solvable spin-orbital model that can be regarded as a classical analogue of the celebrated Kitaev honeycomb model and describes interactions between Rydberg ato…
Ferrimagnetic Kitaev spin liquids in mixed spin 1/2 spin 3/2 honeycomb magnets
Willian Natori, Yang Yang, Hui-Ke Jin +2
We explore the potential experimental realization of the mixed-spin Kitaev model in materials such as ZrRuCl, where spin-1/2 and spin-3/2 ions occupy distinct s…
Quantum liquids of the S=3/2 Kitaev honeycomb and related Kugel-Khomskii models
Willian M. H. Natori, Hui-Ke Jin, Johannes Knolle
The Kitaev honeycomb model (KHM) is unique among the spin- Kitaev models due to a massive ground state quasi-degeneracy that hampered previous numerical and analytical s…
An Exact Chiral Amorphous Spin Liquid
Gino Cassella, Peru D'Ornellas, Thomas Hodson +2
Topological insulator phases of non-interacting particles have been generalized from periodic crystals to amorphous lattices, which raises the question whether topologically ordere…
Twisting the Dirac cones of the SU(4) spin-orbital liquid on the honeycomb lattice
Hui-Ke Jin, W. M. H. Natori, Johannes Knolle
By combining the density matrix renormalization group (DMRG) method with Gutzwiller projected wave functions, we study the SU(4) symmetric spin-orbital model on the honeycomb latti…
Optical phonons coupled to a Kitaev spin liquid
A. Metavitsiadis, W. Natori, J. Knolle +1
Emergent excitation continua in frustrated magnets are a fingerprint of fractionalization, characteristic of quantum spin-liquid states. Recent evidence from Raman scattering for a…
Local Probes for Charge-Neutral Edge States in Two-Dimensional Quantum Magnets
Johannes Feldmeier, Willian Natori, Michael Knap +1
The bulk-boundary correspondence is a defining feature of topological states of matter. However, for quantum magnets such as spin liquids or topological magnon insulators a direct…
Dynamics of a two-dimensional quantum spin-orbital liquid: spectroscopic signatures of fermionic magnons
Willian M. H. Natori, Johannes Knolle
We provide an exact study of dynamical correlations for the quantum spin-orbital liquid phases of an SU(2)-symmetric Kitaev honeycomb lattice model. We show that the spin dynamics…
SU(4) Heisenberg model on the honeycomb lattice with exchange-frustrated perturbations: implications for twistronics and Mott insulators
W. M. H. Natori, R. Nutakki, R. G. Pereira +1
The SU(4)-symmetric spin-orbital model on the honeycomb lattice was recently studied in connection to correlated insulators such as the Mott insulator BaCuSbO$_…
Orbital Magnetic Field Effects in Mott Insulators with Strong Spin-Orbit Coupling
Willian M. H. Natori, Roderich Moessner, Johannes Knolle
We study the effect of a magnetic field on the low energy description of Mott insulators with strong spin-orbit (SO) coupling. In contrast to the standard case of the Hubbard model…
SU(4)-symmetric spin-orbital liquids on the hyperhoneycomb lattice
Willian M. H. Natori, Eric C. Andrade, Rodrigo G. Pereira
We study the effective spin-orbital model that describes the magnetism of 4 or 5 Mott insulators in ideal tricoordinated lattices. In the limit of vanishing Hund's coupli…
Dynamics of a j=3/2 quantum spin liquid
Willian Natori, Maria Daghofer, Rodrigo Pereira
We study a spin-orbital model for 4 or 5 Mott insulators in ordered double perovskites with strong spin-orbit coupling. This model is conveniently written in terms of…
Chiral spin-orbital liquids with nodal lines
W. M. H. Natori, E. C. Andrade, E. Miranda +1
Strongly correlated materials with strong spin-orbit coupling hold promise for realizing topological phases with fractionalized excitations. Here we propose a chiral spin-orbital l…
