Excited states of 4He droplets [PDF]
, 2001 We study low-lying excited states of 4He clusters up to a cluster size of 40 atoms in a variational framework. The ansatz wave function combines two- and three-body correlations, coming from a translationally invariant configuration interaction ...

Engineering a Spin‐Orbit Bandgap in Graphene‐Tellurium Heterostructures
Advanced Functional Materials, EarlyView.Tellurium intercalation in epitaxial graphene on Ir(111) enables the emergence of a spin–orbit‐induced bandgap with energy spin splitting. By combining STM, ARPES, spin‐resolved ARPES, and DFT, two structural phases are identified, both exhibiting tunable electronic doping.
