  • Experiments on twisted bilayer graphene point to various interaction-induced phases, including the non-Fermi liquid, but its unambiguous assignment remains challenging. Here, using simultaneous transport and thermoelectric power measurements, the authors identify non-Fermi liquid signatures at low twist angle.

  • Twisted bilayer graphene hosts a zoo of rich correlated electronic phases. Here, the authors explore the phase diagram of a twisted bilayer graphene/tungsten diselenide heterostructure and uncover a series of delicate Fermi surface reconstructions and signatures of orbital magnetism.

  • Correlated insulating states are common in twisted bilayer graphene when the density of carriers is close to an integer per moiré unit cell. Now, such states emerge at half-integer fillings and show signs of being spin or charge density waves.
