Plasmon dynamics in graphene
Suheng Xu, Birui Yang, Nishchhal Verma +15
Plasmon are collective oscillations of mobile electrons with dynamics controlled by their charge stiffness("Drude weight"). Using terahertz spacetime metrology, we probe Plasmon dy…
Nano-photocurrent mapping of local electronic structure in twisted bilayer graphene
Sai S. Sunku, Alexander S. McLeod, Tobias Stauber +10
We report a combined nano-photocurrent and infrared nanoscopy study of twisted bilayer graphene (TBG) enabling access to the local electronic phenomena at length scales as short as…
Harnessing Ultraconfined Graphene Plasmons to Probe the Electrodynamics of Superconductors
A. T. Costa, P. A. D. Gonçalves, D. N. Basov +3
We show that the Higgs mode of a superconductor, which is usually challenging to observe by far-field optics, can be made clearly visible using near-field optics by harnessing ultr…
Subdiffractional focusing and guiding of polaritonic rays in a natural hyperbolic material
S. Dai, Q. Ma, T. Andersen +11
Uniaxial materials whose axial and tangential permittivities have opposite signs are referred to as indefinite or hyperbolic media. In such materials light propagation is unusual,…
Determination of the electronic structure of bilayer graphene from infrared spectroscopy results
L. M. Zhang, Z. Q. Li, D. N. Basov +3
We present an experimental study of the infrared conductivity, transmission, and reflection of a gated bilayer graphene and their theoretical analysis within the Slonczewski-Weiss-…
