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…
Uniaxial plasmon polaritons charge transfer at the graphene/CrSBr interface
Daniel J. Rizzo, Eric Seewald, Fangzhou Zhao +24
Graphene is a privileged 2D platform for hosting confined light-matter excitations known as surface plasmon-polaritons (SPPs), as it possesses low intrinsic losses with a high degr…
Good plasmons in a bad metal
Francesco L. Ruta, Yinming Shao, Swagata Acharya +12
Correlated materials may exhibit unusually high resistivity increasing linearly in temperature, breaking through the Mott-Ioffe-Regel bound, above which coherent quasiparticles are…
Semi-Dirac Fermions in a Topological Metal
Yinming Shao, Seongphill Moon, A. N. Rudenko +14
Topological semimetals with massless Dirac and Weyl fermions represent the forefront of quantum materials research. In two dimensions (2D), a peculiar class of fermions that are ma…
Visualizing moiré ferroelectricity via plasmons and nano-photocurrent in graphene/twisted-WSe2 structures
Shuai Zhang, Yang Liu, Zhiyuan Sun +28
Ferroelectricity, a spontaneous and reversible electric polarization, is found in certain classes of van der Waals (vdW) material heterostructures. The discovery of ferroelectricit…
In-plane anisotropy in biaxial ReS2 crystals probed by nano-optical imaging of waveguide modes
Fabian Mooshammer, Sanghoon Chae, Shuai Zhang +9
Near-field imaging has emerged as a reliable probe of the dielectric function of van der Waals crystals. In principle, analyzing the propagation patterns of subwavelength waveguide…
