Tunable lattice reconstruction and bandwidth of flat bands in magic-angle twisted bilayer graphene
Yi-Wen Liu, Ying Su, Xiao-Feng Zhou +10
The interplay between interlayer van der Waals interaction and intralayer lattice distortion can lead to structural reconstruction in slightly twisted bilayer graphene (TBG) with t…
Evidence of electron-electron interactions around Van Hove singularities of a graphene Moiré superlattice
Si-Yu Li, Ke-Qin Liu, Long-Jin Yin +7
A variety of new and interesting correlated states have been predicted in graphene monolayer doped to Van Hove singularities (VHSs) of its density-of-state (DOS). However, tuning t…
Quantum corrections in nanoplasmonics: shape, scale, and material
Thomas Christensen, Wei Yan, Antti-Pekka Jauho +2
The classical treatment of plasmonics is insufficient at the nanometer-scale due to quantum mechanical surface phenomena. Here, an extension to the classical paradigm is reported w…
Quantum plasmonics: An energy perspective to quantify nonclassical effects
Wei Yan, N. Asger Mortensen
Plasmons are commonly interpreted with classical electrodynamics, while nonclassical effects may influence the dynamics of plasmon resonances as the plasmon confinement is approach…
Kerr nonlinearity and plasmonic bistability in graphene nanoribbons
Thomas Christensen, Wei Yan, Antti-Pekka Jauho +2
We theoretically examine the role of Kerr nonlinearities for graphene plasmonics in nanostructures, specifically in nanoribbons. The nonlinear Kerr interaction is included semiclas…
Projected-Dipole Model for Quantum Plasmonics
Wei Yan, Martijn Wubs, N. Asger Mortensen
Quantum effects of plasmonic phenomena have been explored through ab-initio studies, but only for exceedingly small metallic nanostructures, leaving most experimentally relevant st…
