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$_3…
Random-bond disorder in two-dimensional non-collinear XY antiferromagnets: From quasi-long-range order to spin glass
Santanu Dey, Eric C. Andrade, Matthias Vojta
We study effects of quenched bond disorder in frustrated easy-plane antiferromagnets in two space dimensions, using a combination of analytical and numerical techniques. We conside…
SU(4) Heisenberg model on the honeycomb lattice with exchange-frustrated perturbations: implications for twistronics and Mott insulators
W. M. H. Natori, R. Nutakki, R. G. Pereira +1
The SU(4)-symmetric spin-orbital model on the honeycomb lattice was recently studied in connection to correlated insulators such as the Mott insulator BaCuSbO$_…
Destruction of long-range order in non-collinear two-dimensional antiferromagnets by random-bond disorder
Santanu Dey, Eric C. Andrade, Matthias Vojta
We consider frustrated Heisenberg antiferromagnets, whose clean-limit ground state is characterized by non-collinear long-range order with non-zero vector chirality, and study the…
Conventional superconductivity in quasicrystals
Ronaldo N. Araújo, Eric C. Andrade
Motivated by a recent experimental observation of superconductivity in the Al-Zn-Mg quasicrystal, we study the low-temperature behavior of electrons moving in the quasiperiodic pot…
Magnetization processes of zigzag states on the honeycomb lattice: Identifying spin models for -RuCl and NaIrO
Lukas Janssen, Eric C. Andrade, Matthias Vojta
We study the field-induced magnetization processes of extended Heisenberg-Kitaev models on the honeycomb lattice, taking into account off-diagonal and longer-range exchange interac…
