Energy-resolved spin correlation measurements: Decoding transverse spin dynamics in weakly interacting Fermi gases
Physical Review A.
The authors measure transverse spin correlations in energy space to uncover hidden spin dynamics in a weakly interacting Fermi gas. The correlation functions reveal the microscopic structure of a demagnetizing or magnetizing synthetic spin lattice, which models a collective Heisenberg Hamiltonian, and provide new observables for studies of transitions between dynamical phases.
