    • Experimental signatures of the transition from acoustic plasmon to electronic sound in graphene 

      Barcons Ruiz, David; Hesp, Niels; Sheinfux, Hanan Herzig; Ramos Marimón, Carlos; Maissen, Curdin Martin; Principi, Alessandro; Asgari, Reza; Taniguchi, Takashi; Watanabe, Kenji; Polini, Marco; Hillenbrand, Rainer; Torre, Iacopo; Koppens, Frank (2023-09-29)
      Article
      Open Access
      Fermi liquids respond differently to perturbations depending on whether their frequency is higher (collisionlessregime) or lower (hydrodynamic regime) than the interparticle collision rate. This results in a different ...

    • Highly confined low-loss plasmons in graphene–boron nitride heterostructures 

      Woessner, Achim; Lundeberg, Mark B.; Gao, Yuanda; Principi, Alessandro; Alonso-González, Pablo; Carrega, Matteo; Watanabe, Kenji; Taniguchi, Takashi; Vignale, Giovanni; Polini, Marco; Hone, James; Hillenbrand, Rainer; Koppens, Frank H. L. (Nature Publishing Group, 2014-12-22)
      Article
      Open Access
      Graphene plasmons were predicted to possess simultaneous ultrastrong field confinement and very low damping, enabling new classes of devices for deep-subwavelength metamaterials, single-photon nonlinearities, extraordinarily ...
