Superluminal plasmons with resonant gain in population inverted bilayer graphene
Tony Low, Pai-Yen Chen, D. N. Basov
AB-stacked bilayer graphene with a tunable electronic bandgap in excess of the optical phonon energy presents an interesting active medium, and we consider such theoretical possibi…
Third-order optical conductivity of an electron fluid
Zhiyuan Sun, D. N. Basov, M. M. Fogler
We derive the nonlinear optical conductivity of an isotropic electron fluid at frequencies below the interparticle collision rate. In this regime, governed by hydrodynamics, the co…
Imaging the nanoscale phase separation in vanadium dioxide thin films at terahertz frequencies
H. T. Stinson, A. Sternbach, O. Najera +8
We use apertureless scattering near-field optical microscopy (SNOM) to investigate the nanoscale optical response of vanadium dioxide (VO2) thin films through a temperature-induced…
Manipulation and steering of hyperbolic surface polaritons in hexagonal boron nitride
S. Dai, M. Tymchenko, Y. Yang +8
Hexagonal boron nitride (hBN) is a natural hyperbolic material that supports both volume-confined hyperbolic polaritons (HPs) and sidewall-confined hyperbolic surface polaritons (H…
Plasmon reflections by topological electronic boundaries in bilayer graphene
Bor-Yuan Jiang, Guang-Xin Ni, Zachariah Addison +7
Domain walls separating regions of AB and BA interlayer stacking in bilayer graphene have attracted attention as novel examples of structural solitons, topological electronic bound…
Artifact Free Transient Near-Field Nanoscopy
Aaron Sternbach, James Hinton, Tetiana Slusar +11
We report on the first implementation of ultrafast near field nanoscopy carried out with the transient pseudoheterodyne detection method (Tr-pHD). This method is well suited for ef…
