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…
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…
Renormalized Classical Theory of Quantum Magnets
David Dahlbom, Hao Zhang, Zoha Laraib +3
We derive a renormalized classical spin (RCS) theory for quantum magnets by constraining a generalized classical theory that includes all multipolar fluctuations to a red…
Cubic Double Perovskites Host Noncoplanar Spin Textures
Joseph A. M. Paddison, Hao Zhang, Jiaqiang Yan +8
Magnetic materials with noncoplanar magnetic structures can show unusual physical properties driven by nontrivial topology. Topologically-active states are often multi-q structures…
