  • Three-dimensional droplets of swirling superfluids

    A new method for the creation of 3D solitary topological modes, corresponding to vortical droplets of a two-component dilute superfluid, is presented. We use the recently introduced system of nonlinearly coupled Gross-Pitaevskii ...

    The on-demand tailoring of the properties of light, such as phase, polarization or spatial shape, has completely changed the landscape of photonic-based applications. In this way, complex light fields have become an ...
  • Space QUEST mission proposal: experimentally testing decoherence due to gravity 

    Joshi, Siddarth Koduru; Pienaar, Jacques; Ralph, Timothy C.; Pérez Torres, Juan (2018-06-12)

    Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum correlations, such as entanglement, may exhibit different behavior to purely classical ...
  • Optical sectioning in induced coherence tomography with frequency-entangled photons 

    Valles Marin, Adam; Jimenez Machado, Gerard; Salazar Serrano, Luis Jose; Pérez Torres, Juan (American Physical Society, 2018-02-14)
    Artículo

    We demonstrate a different scheme to perform optical sectioning of a sample based on the concept of induced coherence [Zou et al., Phys. Rev. Lett. 67, 318 (1991)]. This can be viewed as a different type of optical coherence ...

  • Cavity solitons in a microring dimer with gain and loss 

    Milián, Carles; Kartashov, Yaroslav V.; Skryabin, Dmitry V.; Torner Sabata, Lluís (2018-02-20)
    Artículo

    We address a pair of vertically coupled microring resonators with gain and loss pumped by a single-frequency field. Coupling between microrings results in a twofold splitting of the single microring resonance that increases ...
  • Lieb polariton topological insulators 

    Li, Chunyan; Ye, Fangwei; Chen, Xianfeng; Kartashov, Yaroslav V.; Ferrando, Albert; Torner Sabata, Lluís; Skryabin, Dmitry V. (American Physical Society, 2018-02-12)

    We predict that the interplay between the spin-orbit coupling, stemming from the transverse electric–transverse magnetic energy splitting, and the Zeeman effect in semiconductor microcavities supporting exciton-polariton ...
  • Bound states in the continuum in a two-dimensional PT - symmetric system 

    Kartashov, Yaroslav V.; Milian, Carles; Konotop, Vladimir V; Torner Sabata, Lluís (2018-02-01)
    Artículo

    We address a 2D parity-time (¿¿)-symmetric structure built as a chain of waveguides, where all waveguides except for the central one are conservative, while the central one is divided into two halves with gain and losses. ...
  • STED imaging performance estimation by means of Fourier transform analysis 

    Merino, David; Mallabiabarrena, Arrate; Andilla, Jordi; Artigas García, David; Zimmermann, Timo; Loza Alvarez, Pablo (2017-05-01)
    Artículo

    Due to relatively high powers used in STED, biological samples may be affected by the illumination in the process of image acquisition. Similarly, the performance of the system may be limited by the sample itself. Optimization ...
  • Bound states in the continuum in anisotropic structures

    We report theoretical and experimental observation of radiationless bound states in the continuum (BIC) in waveguiding anisotropic structures. BICs may have all possible polarizations and be the only possible boundstates ...
  • Bound states in the continuum in spin-orbit-coupled atomic systems 

    Kartashov, Yaroslav V.; Konotop, Vladimir V; Torner Sabata, Lluís (2017-09-14)
    Artículo
    Acceso restringido por política de la editorial
    We show that the interplay between spin-orbit coupling and Zeeman splitting in atomic systems can lead to the existence of bound states in the continuum (BICs) supported by trapping potentials. Such states have energies ...
  • Gap solitons on a ring

    Artículo

    We introduce a new species of gap solitons (GSs) supported by an azimuthally modulated guiding ring in defocusing cubic media. The periodicity in the azimuthal direction strongly modifies properties and existence domains ...
