5. Abstract: Twisted layers of two-dimensional materials such as graphene and transition-metal dichalcogenides have emerged as a new platform of novel electronic structures. Since they have large moiré supercells typically, it becomes a challenge to perform accurate theoretical calculations of their electronic structures. Here, we present atomistic approaches to atomic and phononic structures of twisted graphene layers [1-3] and twisted transition-metal dichalcogenide layers [4-5], and discuss their atomic, electronic, and phononic properties [1-5].
