Disentangling multi-spin dynamic correlations in the Heisenberg spin-$\frac{1}{2}$ chain
V. K . Bhartiya, U. Kumar, T. Kim, S. Fan et autres
Higher-order correlations are essential for understanding exotic phases and uncovering universal aspects of quantum dynamics. While inelastic neutron scattering provides well-established access to two-particle correlations, measuring correlations in solids involving more than two particles remains a major challenge. Focusing on magnetic excitations …
