Lattice relaxation, mirror symmetry and magnetic field effects on ultraflat bands in twisted trilayer graphene
Zewen Wu, Zhen Zhan, Shengjun Yuan
Twisted graphene multilayers exhibit strongly correlated insulating states and superconductivity due to the presence of ultraflat bands near the charge neutral point. In this paper…
Collective excitations and plasmon spectrum in twisted bilayer graphene near the magic angle
Xueheng Kuang, Zhen Zhan, Shengjun Yuan
Twisted bilayer graphene with tiny rotation angles have drawn significant attention due to the observation of the unconventional superconducting and correlated insulating behaviors…

Electronic structure of 30° twisted double bilayer graphene
Guodong Yu, Zewen Wu, Zhen Zhan +2
In this paper, the electronic properties of 30° twisted double bilayer graphene, which loses the translational symmetry due to the incommensurate twist angle, are studied by means…
Dodecagonal bilayer graphene quasicrystal and its approximants
Guodong Yu, Zewen Wu, Zhen Zhan +2
Dodecagonal bilayer graphene quasicrystal has 12-fold rotational order but lacks translational symmetry which prevents the application of band theory. In this paper, we study the e…
