    • openAccess   Electrons, holes, and excitons in GaAs polytype quantum dots 

      Climente, Juan I.; Segarra, Carlos; Rajadell Viciano, Fernando; Planelles, Josep American Institute of Physics (2016)
      Single and multi-band k⋅p Hamiltonians for GaAs crystal phase quantum dots are used to assess ongoing experimental activity on the role of such factors as quantum confinement, spontaneous polarization,valence band mixing, ...

    • closedAccess   Partially-coherent spirally-polarized gradual-edge imaging 

      Pérez-Aviñoa, Marcos; Martínez-Herrero, Rosario; Vallmitjana, Santiago; Latorre Carmona, Pedro; Juvells, Ignasi; Carnicer, Artur Elsevier (2019)
      In this work we develop a partially-coherent spirally-polarized imaging system for generating gradual edge detection images. A rotating diffuser is used for producing illumination sources with tunable degree of coherence. Using ...

    • openAccess   Poincaré-sphere representation of phase-mostly twisted nematic liquid crystal spatial light modulators 

      Durán, Vicente; Clemente Pesudo, Pedro Javier; Martínez-León, Lluís; Climent, Vicent; Lancis, Jesús Institute of Physics (2009)
      We establish necessary conditions in order to design a phase-only wave front modulation system from a liquid crystal display. These conditions determine the dependence of the polarization state of the light emerging from ...

    • closedAccess   Synthesis and characterization of the conductivity and polarization processes in supported ionic liquid-like phases (SILLPs) 

      Compañ, Vicente; Mollá, Sergio; Garcia-Verdugo, Eduardo; Luis, Santiago V.; Burguete, M. Isabel Elsevier (2012)
      Different crosslinked polystyrene resins containing ionic liquid fragments covalently attached (supported ionic liquid-like phases: SILLPs) have been prepared and their conductivity has been studied by means of dielectric ...

    • openAccess   The behavior of Stanley depth under polarization 

      Ichim, Bogdan; Katthän, Lukas; Moyano-Fernández, Julio José Elsevier (2015-10)
      Let K be a field, R = K [ X 1 , ..., X n ]be the polynomial ring and J I be two monomial ideals in R . In this paper we show that sdepth I/J − depth I/J = sdepth I p /J p − ...

    • openAccess   Use of principal states of polarization of a liquid crystal device to achieve a dynamical modulation of broadband beams 

      Durán, Vicente; Clemente Pesudo, Pedro Javier; Lancis, Jesús Optical Society of America (2009)
      A spatially resolved polarization switcher operating over a bandwidth of 200 nm is demonstrated. The system is based on liquid crystal technology and no specific-purpose birefringent element is required. The procedure is ...
