Charge order and Mott insulating ground states in small-angle twisted bilayer graphene [PDF]
, 2020 In this work, we determine states of electronic order of small-angle twisted bilayer graphene. Ground states are determined for weak and strong couplings which are representatives for varying distances of the twist-angle from its magic value. In the weak-

Brightened spin-triplet interlayer excitons and optical selection rules in van der Waals heterobilayers [PDF]
, 2018 We investigate the optical properties of spin-triplet interlayer excitons in heterobilayer transition metal dichalcogenides in comparison with the spin-singlet ones.

Signatures of moir\'e-trapped valley excitons in MoSe$_2$/WSe$_2$ heterobilayers [PDF]
, 2018 The creation of moir\'e patterns in crystalline solids is a powerful approach to manipulate their electronic properties, which are fundamentally influenced by periodic potential landscapes. In 2D materials, a moir\'e pattern with a superlattice potential

Intralayer Phonons in Multilayer Graphene Moiré Superlattices
Research, 2022 Moiré pattern in twisted multilayers (tMLs) induces many emergent phenomena by subtle variation of atomic registry to modulate quasiparticles and their interactions, such as superconductivity, moiré excitons, and moiré phonons.
