  • Topological states in partially-PT-symmetric azimuthal potentials 

    Kartashov, Yaroslav V.; Konotop, Vladimir V; Torner Sabata, Lluís (2015-11-04)
    Article
    Open Access
    We introduce partially-parity-time (pPT)-symmetric azimuthal potentials composed from individual PT-symmetric cells located on a ring, where two azimuthal directions are nonequivalent in a sense that in such potential ...
  • Globally-linked vortex clusters 

    Crasovan, L C; Vekslerchik, V; Mihalache, Dumitru; Pérez Torres, Juan; Perez-Garcia, V M; Torner Sabata, Lluís (Kluwer, 2004-09-30)
    Part of book or chapter of book
    Restricted access - publisher's policy
    We show the existence of a rich variety of fully stationary vortex structures made of an increasing number of vortices nested in paraxial wave fields confined by symmetric and asymmetric harmonic trapping potentials in ...
  • Self-deflecting plasmonic lattice solitons and surface modes in chirped plasmonic arrays 

    Li, Chunyan; Cui, Ran; Ye, Fangwei; Kartashov, Yaroslav V.; Torner Sabata, Lluís; Chen, Xianfeng (2015-03-15)
    Article
    Restricted access - publisher's policy
    We show that chirped metal-dielectric waveguide arrays with focusing cubic nonlinearity can support plasmonic lattice solitons that undergo self-deflection in the transverse plane. Such lattice solitons are deeply subwavelength ...
  • Dynamic versus Anderson wave-packet localization 

    Borovkova, Olga V.; Lobanov, Valery E.; Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (2015-06-18)
    Article
    Open Access
    We address the interplay between two fundamentally different wave-packet localization mechanisms, namely, resonant dynamic localization due to collapse of quasienergy bands in periodic media and disorder-induced Anderson ...
  • Quantum many-body models with cold atoms coupled to photonic crystals 

    Douglas, J. S.; Habibian, H.; Hung, C.-L; Gorshkov, A. V.; Kimble, H. J.; Chang, Darrick E. (Nature, 2015-04-06)
    Article
    Open Access
    Using cold atoms to simulate strongly interacting quantum systems is an exciting frontier of physics. However, because atoms are nominally neutral point particles, this limits the types of interaction that can be produced. ...
  • Twisted toroidal vortex solitons in inhomogeneous media with repulsive nonlinearity 

    Kartashov, Yaroslav V.; Malomed, Boris A.; Shnir, Yasha; Torner Sabata, Lluís (2014-12-24)
    Article
    Open Access
    Toroidal modes in the form of so-called Hopfions, with two independent winding numbers, a hidden one (twist s), which characterizes a circular vortex thread embedded into a three-dimensional soliton, and the vorticity ...
  • Direction-sensitive transverse velocity measurement by phase-modulated structured light beams 

    Rosales Guzmán, Carmelo; Hermosa, Nathaniel; Belmonte Molina, Aniceto; Pérez Torres, Juan (2014-09-15)
    Article
    Restricted access - publisher's policy
    The use of structured light beams to detect the velocity of targets moving perpendicularly to the beam's propagation axis opens new avenues for remote sensing of moving objects. However, determining the direction of motion ...
  • Nano guiding of light using Dyakonov waves 

    Takayama, Osamu; Torner Sabata, Lluís; Artigas García, David (2014-12)
    Article
    Restricted access - publisher's policy
    This special issue of Optics & Photonics News highlights the most exciting peer-reviewed optics research to have emerged over the past 12 months.
  • Fast monitoring of in-vivo conformational changes in myosin using single scan polarization- SHG microscopy 

    Psilodimitrakopoulos, Sotiris; Loza Alvarez, Pablo; Artigas García, David (2014-12-01)
    Article
    Restricted access - publisher's policy
    Fast imaging of molecular changes under high-resolution and label-free conditions are essential for understanding in-vivo processes, however, current techniques are not able to monitor such changes in real time. Polarization ...
  • Tunable beam displacer 

    Salazar Serrano, Luis Jose; Valencia, Alejandra; Pérez Torres, Juan (2015-03-17)
    Article
    Open Access
    We report the implementation of a tunable beam displacer, composed of a polarizing beam splitter(PBS) and two mirrors, that divides an initially polarized beam into two parallel beams whose separation can be continuously ...
