TI MPS with permutational symmetry (entanglement similar across bipartitions) are shown to be trivial (product states or few superpositions); extends to generic MPS and states like W and Dicke approximately.
Experimental observation that light from a driven dense ensemble of two-level atoms exhibits non-Gaussian statistics due to higher-order atomic correlations without first-order coherence.
