  - "We compute the rotational anisotropy of the free energy of \U0001D6FC−RuCl3 in
    an external magnetic field. This quantity, known as the magnetotropic susceptibility,
    \U0001D458, relates to the second derivative of the free energy with respect to
    the angle of rotation. We have used approximation-free, auxiliary-field quantum
    Monte Carlo simulations for a realistic model of \U0001D6FC−RuCl3 and optimized
    the path integral to alleviate the negative sign problem. This allows us to reach
    temperatures down to 30K—an energy scale below the dominant Kitaev coupling. We
    demonstrate that the magnetotropic spin susceptibility in this model of \U0001D6FC−RuCl3
    displays scaling behavior \U0001D458=\U0001D447⁢\U0001D453⁡(\U0001D435/\U0001D447)
    at high temperatures. Once the uniform susceptibility departs from the Curie law
    (i.e., at the energy scale of the exchange interactions), it appears to transition
    to an emergent scalinglike behavior, characterized by a different function \U0001D453
    at lower temperatures, stemming from the locality of torque fluctuations. We observe
    a remarkable numerical match between experiment and simulations and we also find
    qualitative agreement with the pure Kitaev model. In comparison, for the XXZ Heisenberg
    Hamiltonian, the scaling \U0001D458=\U0001D447⁢\U0001D453⁡(\U0001D435/\U0001D447)
    breaks down at a temperature scale where the uniform spin susceptibility deviates
    from the Curie law and never reemerges at low temperatures.@eng"
