Nonlinear Spectroscopy as a Magnon Breakdown Diagnosis and its Efficient Simulation
David A. S. Kaib, Marius Möller, Roser Valenti
Identifying quantum spin liquids, magnon breakdown, or fractionalized excitations in quantum magnets is an ongoing challenge due to the ambiguity of possible origins of excitation…
Anisotropy of the zigzag order in the Kitaev honeycomb magnet -RuBr
John S. Pearce, David A. S. Kaib, Zeyu Ma +5
Kitaev materials often order magnetically at low temperatures due to the presence of non-Kitaev interactions. Torque magnetometry is a very sensitive technique for probing the magn…
Theory of Intrinsic Phonon Thermal Hall Effect in -RuCl
Ramesh Dhakal, David A. S. Kaib, Kate Choi +3
We apply a recently developed first-principles based approach for treating generic spin-phonon couplings in materials with strong spin-orbit coupling to study -RuCl. Of part…
Microscopic origin of temperature-dependent magnetism in spin-orbit-coupled transition metal compounds
Ying Li, Ram Seshadri, Stephen D. Wilson +2
A few and transition metal compounds with various electron fillings were recently found to exhibit magnetic susceptibilities and magnetic moments that deviate from th…
Spin-phonon interactions on the kagome lattice: Dirac spin liquid versus valence-bond solids
Francesco Ferrari, Federico Becca, Roser Valenti
We investigate the impact of the spin-phonon coupling on the S=1/2 Heisenberg model on the kagome lattice. For the pure spin model, there is increasing evidence that the low-energy…
Theory of moiré magnetism in twisted bilayer -RuCl
Muhammad Akram, Jesse Kapeghian, Jyotirish Das +3
Twisted heterostructures of van der Waals materials have received much attention for their many remarkable properties. Here, we present a comprehensive theory of the long-range ord…
Symmetric Kondo Lattice States in Doped Strained Twisted Bilayer Graphene
H. Hu, G. Rai, L. Crippa +7
We use the topological heavy fermion (THF) model and its Kondo Lattice (KL) formulation to study the symmetric Kondo state in twisted bilayer graphene. Via a large-N approximation,…
Thermodynamic perspective on the field-induced behavior of -RuCl
S. Bachus, D. A. S. Kaib, Y. Tokiwa +7
Measurements of the magnetic Grüneisen parameter () and specific heat on the Kitaev material candidate -RuCl are used to access in-plane field- and temperature-dependen…
Competition between spin-orbit coupling, magnetism, and dimerization in the honeycomb iridates: -LiIrO under pressure
V. Hermann, M. Altmeyer, J. Ebad-Allah +9
Single-crystal x-ray diffraction studies with synchrotron radiation on the honeycomb iridate -LiIrO reveal a pressure-induced structural phase transition with symmet…
