Experimental Evidence for Non-spherical Magnetic Form Factor in Ru
Colin L. Sarkis, John W. Villanova, Casey Eichstaedt +9
The Mott insulator -RuCl has generated great interest in the community due to its possible field-induced Kitaev quantum spin liquid state. Despite enormous effort spent tryi…
Static and dynamical magnetic properties of the extended Kitaev-Heisenberg model with spin vacancies
Shaozhi Li, Randy S. Fishman, Tom Berlijn
Motivated by the potential to suppress the antiferromagnetic long-range order in favor of the long-sought-after Kitaev quantum spin liquid state, we study the effect of spin vacanc…
Spin wave Hamiltonian and anomalous scattering in NiPS
A. Scheie, Pyeongjae Park, J. W. Villanova +8
We report a comprehensive spin wave analysis of the semiconducting honeycomb van der Waal antiferromagnet NiPS. Using single crystal inelastic neutron scattering, we map out th…
Non-linear magnons and exchange Hamiltonians of delafossite proximate quantum spin liquids
A. O. Scheie, Y. Kamiya, Hao Zhang +20
Quantum spin liquids (QSL) are theoretical states of matter with long-range entanglement and exotic quasiparticles. However, they generally elude quantitative theory, rendering the…
Variation of carrier density in semimetals via short-range correlation: A case study with nickelate NdNiO
Ruoshi Jiang, Zi-Jian Lang, Tom Berlijn +1
Carrier density is one of the key controlling factors of material properties, particularly in controlling the essential correlations in strongly correlated materials. Typically, ca…
The Role of the Third Dimension in Searching Majorana Fermions in -RuCl via Phonons
Sai Mu, Kiranmayi D. Dixit, Xiaoping Wang +12
Understanding phonons in -RuCl is critical to analyze the controversy around the observation of the half-integer thermal quantum Hall effect. While many studies have focused…
Quasiparticle Interference of the van-Hove singularity in SrRuO
A. Kreisel, C. A. Marques, L. C. Rhodes +7
The single-layered ruthenate SrRuO is one of the most enigmatic unconventional superconductors. While for many years it was thought to be the best candidate for a chiral $p…
Deriving models for the Kitaev spin-liquid candidate material -RuCl from first principles
Casey Eichstaedt, Yi Zhang, Pontus Laurell +3
We use the constrained random phase approximation (cRPA) to derive from first principles the Ru- Wannier function based model for the Kitaev spin-liquid candidate material…
Decoupling carrier concentration and electron-phonon coupling in oxide heterostructures observed with resonant inelastic x-ray scattering
D. Meyers, Ken Nakatsukasa, Sai Mu +19
We report the observation of multiple phonon satellite features in ultra thin superlattices of form SrIrO/SrTiO using resonant inelastic x-ray scattering. As the valu…
Itinerant Antiferromagnetism in RuO
T. Berlijn, P. C. Snijders, O. Delaire +9
Bulk rutile RuO has long been considered a Pauli paramagnet. Here we report that RuO exhibits a hitherto undetected lattice distortion below approximately 900 K. The distor…
Giant Spin Gap and Magnon Localization in the Disordered Heisenberg Antiferromagnet Sr2Ir1-xRuxO4
Yue Cao, Xuerong Liu, Wenhu Xu +15
We study the evolution of magnetic excitations in the disordered two-dimensional antiferromagnet Sr2Ir1-xRuxO4. A gigantic magnetic gap greater than 40 meV opens at x = 0.27 and in…
Relevance of the Heisenberg-Kitaev model for the honeycomb lattice iridates A_2IrO_3
Yogesh Singh, S. Manni, J. Reuther +5
Combining thermodynamic measurements with theoretical density functional and thermodynamic calculations we demonstrate that the honeycomb lattice iridates A2IrO3 (A = Na, Li) are m…
