  • Exploring the spin-resolved Hofstadter spectrum in the presence of interactions is challenging. Now, a series of magnetic phase transitions are observed as individual Hofstadter bands are filled, allowing the exchange interactions to be mapped out.

  • Magic-angle twisted bilayer graphene (MATBG) hosts flat electronic bands allowing for a rich variety of correlated electronic states. Here, using a scanning single electron transistor, Yu et al find thermodynamically gapped ground states in MATBG at several filling factors, with spin-skyrmion charge excitations.

  • The interplay between flat and dispersive bands in moiré materials has not yet been examined in detail. Now, the phase diagram of a transition metal dichalcogenide bilayer shows correlated states arising from both types of band.
