Eclipsing Kitaev: off-diagonal exchange governs the correlated high-field phases of -LiIrO
Vikram Nagarajan, Ioannis Rousochatzakis, Yuanqi Lyu +9
We report a high-field thermodynamic study of the hyperhoneycomb Kitaev material -LiIrO, using magnetotropic susceptibility to resolve its low-temperature field-angle ph…
One-dimensional physics of the frustrated quantum magnet PHCC
Alexander A. Tsirlin, Oleg Janson, Ioannis Rousochatzakis
We report a comprehensive microscopic study of the frustrated quantum magnet PHCC, (CHN)CuCl, using density-functional band-structure calculations combined w…
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…
Spin- Kitaev-Heisenberg model on the honeycomb lattice: A high-order treatment via the many-body coupled cluster method
Marios Georgiou, Ioannis Rousochatzakis, Damian J. J. Farnell +2
We study the spin- Kitaev-Heisenberg model on the honeycomb lattice for , and , by using the coupled cluster method (CCM) of microscopic quantum many-body th…
Geometric frustration and Dzyaloshinskii-Moriya interactions in a quantum star lattice hybrid copper sulfate
Hajime Ishikawa, Yuto Ishii, Takeshi Yajima +6
We study the magnetism of a layered, spin- organic-inorganic copper sulfate, which is a close realization of the star lattice antiferromagnet, one of the playgrounds of ge…
Complex orders and chirality in the classical Kitaev- 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 and the symmetric off-diago…
