Eclipsing Kitaev: off-diagonal exchange governs the correlated high-field phases of $I^^{2}$ -Li $_{2}$ IrO $_{3}$

Vikram Nagarajan, Ioannis Rousochatzakis, Yuanqi Lyu +9

We report a high-field thermodynamic study of the hyperhoneycomb Kitaev material $I^^{2}$ -Li $_{2}$ IrO $_{3}$ , using magnetotropic susceptibility to resolve its low-temperature field-angle p…

Quintuplet condensation in the skyrmionic insulator Cu2OSeO3 at ultrahigh magnetic fields

T. Nomura, I. Rousochatzakis, O. Janson +6

We report ultrahigh magnetic field Faraday rotation results on the chiral helimagnet Cu2OSeO3, the first Mott insulator showing skyrmion lattice phases and a linear magnetoelectric…

Complex orders and chirality in the classical Kitaev- $I^$ model

P. Peter Stavropoulos, Yang Yang, Ioannis Rousochatzakis +1

It is well-recognized that the low-energy physics of many Kitaev materials is governed by two dominant energy scales, the Ising-like Kitaev coupling $K$ and the symmetric off-diago…
