Kernel Polynomial Method for Linear Spin Wave Theory
Harry Lane, Hao Zhang, David Dahlbom +5
Calculating dynamical spin correlations is essential for matching model magnetic exchange Hamiltonians to momentum-resolved spectroscopic measurements. A major numerical bottleneck…
Monte-Carlo ray-tracing studies of multiplexed prismatic graphite analyzers for the cold-neutron triple-axis spectrometer at the High Flux Isotope Reactor
Adit S. Desai, Travis J. Williams, Marcus Daum +4
A modern cold triple-axis spectrometer to study quantum condensed matter systems is planned for the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory. Here, we desc…
Quantum to classical crossover in generalized spin systems -- the temperature-dependent spin dynamics of FeI
D. Dahlbom, D. Brooks, M. S. Wilson +9
Simulating quantum spin systems at finite temperatures is an open challenge in many-body physics. This work studies the temperature-dependent spin dynamics of a pivotal compound, F…
Pressure control of magnetic order and excitations in the pyrochlore antiferromagnet MgCrO
L. S. Nassar, H. Lane, B. Haberl +4
MgCrO is one of the best-known realizations of the pyrochlore-lattice Heisenberg antiferromagnet. The strong antiferromagnetic exchange interactions are perturbed by sm…
Bond-dependent anisotropy and magnon decay in cobalt-based Kitaev triangular antiferromagnet
Chaebin Kim, Sujin Kim, Pyeongjae Park +9
The Kitaev model, a honeycomb network of spins with bond-dependent anisotropic interactions, is a rare example of having a quantum spin liquid ground state. Although most Kitaev mo…
