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…
Detecting giant electron-hole asymmetry in graphene monolayer generated by strain and charged-defect scattering via Landau level spectroscopy
Ke-Ke Bai, Yi-Cong Wei, Jia-Bin Qiao +5
The electron-hole symmetry in graphene monolayer, which is analogous to the inherent symmetric structure between electrons and positrons of the Universe, plays a crucial role in th…
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…
Landau Quantization and Fermi Velocity Renormalization in Twisted Graphene Bilayers
Long-Jing Yin, Jia-Bin Qiao, Wei-Jie Zuo +5
Currently there is a lively discussion concerning Fermi velocity renormalization in twisted bilayers and several contradicted experimental results are reported. Here we study elect…
Spatially resolving unconventional interface Landau quantization in a graphene monolayer-bilayer planar junction
Wei Yan, Si-Yu Li, Long-Jing Yin +3
Graphene hybrid planar structures consisting of two regions with different quantum Hall (QH) states exhibit unusual transport properties1-5, originating from chiral edge states equ…
