Abstract

This article explores the intriguing electronic excitations in sliding bilayer graphene using a tight-binding model and modified layer-based random-phase approximation, unraveling complex electron–electron interactions. By examining the essential electronic properties, the study gains a deeper understanding of the elementary excitation phenomena arising from interlayer coupling-induced hybridization of two-layer Dirac quasiparticles during stacking transitions (AA to AB to AA). This transition results in two distinct plasmon modes and intricate single-particle excitations driven by two Dirac cone distortion and hybridization. This study highlights the evolution of plasmons due to sliding effects in systems with symmetry breaking. These theoretical predictions can be verified by high-resolution measurements of plasmonic properties, providing a solid foundation for further research in this exciting field.
