Quantum loop states in spin-orbital models on the honeycomb lattice

HIGHLIGHTS

• who: Lucile Savary from the Massachusetts Institute have published the research: Quantum loop states in spin-orbital models on the honeycomb lattice, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
• what: The authors show that orbital degrees of freedom provide a simple loop-forming mechanism, and allow to naturally realize the AKLT chain ground_state picture (see Fig 1). The authors note that the model can be generalized to three dimensions (on the hyperhoneycomb lattice40, which shares with the honeycomb lattice the same essential ingredients), where Coulombic phases of U(1) gauge theories are stable39,41,42 . . .
