    • Propagation and localization of quantum dot emission along a gap-plasmonic transmission line 

      Castro-Lopez, M.; Manjavacas, A.; García de Abajo, Francisco Javier; Hulst, Niek F. van (OSA, 2015-11-02)
      Article
      Open Access
      Plasmonic transmission lines have great potential to serve as direct interconnects between nanoscale light spots. The guiding of gap plasmons in the slot between adjacent nanowire pairs provides improved propagation of ...

    • Quantum surface-response of metals revealed by acoustic graphene plasmons 

      Gonçalves, P. A. D.; Christensen, Thomas; Peres, Nuno M. R; Jauho, Antti-Pekka; Epstein, Itai; Koppens, Frank H. L.; Soljačić, Marin; Mortensen, N. Asger (Nature, 2021-06-01)
      Article
      Open Access
      A quantitative understanding of the electromagnetic response of materials is essential for the precise engineering of maximal, versatile, and controllable light–matter interactions. Material surfaces, in particular, are ...

    • Resonances in graphene plasmons 

      Alcaraz Iranzo, David (Universitat Politècnica de Catalunya, 2014-09-09)
      Master thesis
      Open Access
      [ANGLÈS] Graphene is used as a novel, versatile plasmonic material. The most common way to implement resonant light-plasmon coupling is to etch graphene into periodic nanostructures, which is invasive. Here, we study a ...

    • Scalable and tunable periodic graphene nanohole arrays for mid-infrared plasmonics 

      Gopalan, Kavitha K.; Paulillo, Bruno; Mackenzie, David M. A.; Rodrigo, Daniel; Bareza, Néstor; Whelan, Patrick R.; Shivayogimath, Abhay; Pruneri, Valerio (2018-09-12)
      Article
      Open Access
      Despite its great potential for a wide variety of devices, especially mid-infrared biosensors and photodetectors, graphene plasmonics is still confined to academic research. A major reason is the fact that, so far, ...

    • Self-biased reconfigurable graphene stacks for terahertz plasmonics 

      Gomez Diaz, J. S.; Moldovan, C; Capdevila Cascante, Santiago; Romeu Robert, Jordi; Bernard, L. S.; Magrez, A; Ionescu, A. M.; Perruisseau Carrier, Julien (2015-03-01)
      Article
      Open Access
      The gate-controllable complex conductivity of graphene offers unprecedented opportunities for reconfigurable plasmonics at terahertz and mid-infrared frequencies. However, the requirement of a gating electrode close to ...

    • Simulations of radiative shocks and jet formation in laboratory plasmas 

      Velarde, Pedro; González, Matthias; Oliva, Eduardo; Kasperczuk, Andrzej; Pisarczyk, Tadeusz; Ullschmied, Jiri; Stehlé, Chantal; Rus, Bedrich; García Senz, Domingo; Bravo Guil, Eduardo; Relaño, Antonio (IOP Publishing, 2007)
      Conference report
      Restricted access - publisher's policy
      We present the simulations of two relevant hydrodynamical problems related to astrophysical phenomena performed by three different codes. The numerical results from these codes will be compared in order to test both the ...

    • Strong coupling of organic molecules to a plasmonic nano-antenna cavity 

      Gyssels, Lander (Universitat Politècnica de Catalunya, 2022-07-20)
      Master thesis
      Open Access
      The optical properties of molecules can be changed by the presence of a cavity. If the cavity is resonant with a certain transition of the molecules, the molecules couple with the cavity. The coupling is characterized by ...

    • The inverse-square interaction phase diagram: unitarity in the bosonic ground state 

      Astrakharchik, Grigori; Kryuchkov, P. S.; Kurbakov, I. L.; Lozovik, Yu. E. (Multidisciplinary Digital Publishing Institute (MDPI), 2018-06-08)
      Article
      Open Access
      Ground-state properties of bosons interacting via inverse square potential (three dimensional Calogero-Sutherland model) are analyzed. A number of quantities scale with the density and can be naturally expressed in units ...
