Partial magnetic order in kagome spin ice
Eric C. Andrade, Matthias Vojta
Motivated by the observation of partial magnetic order in kagome-based magnets, we study the classical kagome Ising antiferromagnet, known as kagome spin ice, including further-nei…
The phase diagram of a frustrated Heisenberg model: from disorder to order and back again
Michel M. J. Miranda, Igor C. Almeida, Eric C. Andrade +1
We study the effects of bond and site disorder in the classical - Heisenberg model on a square lattice in the order-by-disorder frustrated regime $2J_{2}>\left|J_{1}\…
Susceptibility anisotropy and its disorder evolution in models for Kitaev materials
Eric C. Andrade, Lukas Janssen, Matthias Vojta
Mott insulators with strong spin-orbit coupling display a strongly anisotropic response to applied magnetic fields. This applies in particular to Kitaev materials, with -RuCl$_3…
Heisenberg-Kitaev model in a magnetic field: expansion
Pedro M. Cônsoli, Lukas Janssen, Matthias Vojta +1
The exact solution of Kitaev's spin- honeycomb spin-liquid model has sparked an intense search for Mott insulators hosting bond-dependent Kitaev interactions, of which $\mathr…
Random-bond disorder in two-dimensional non-collinear XY antiferromagnets: From quasi-long-range order to spin glass
Santanu Dey, Eric C. Andrade, Matthias Vojta
We study effects of quenched bond disorder in frustrated easy-plane antiferromagnets in two space dimensions, using a combination of analytical and numerical techniques. We conside…
SU(4) Heisenberg model on the honeycomb lattice with exchange-frustrated perturbations: implications for twistronics and Mott insulators
W. M. H. Natori, R. Nutakki, R. G. Pereira +1
The SU(4)-symmetric spin-orbital model on the honeycomb lattice was recently studied in connection to correlated insulators such as the Mott insulator BaCuSbO$_…
