  • Valagiannopoulos, Constantinos (Institute of Electrical and Electronics Engineers, 2020-07-28)
    Filtering of photonic signals of a certain frequency while suppressing all the others of a specific band for both electromagnetic signal polarizations, becomes possible with a single dielectric layer by properly engineering ...
  • Tulegenov, Dias; Valagiannopoulos, Constantinos (Nature Research, 2020-08-03)
    The controllability of photonic setups is strongly related to how coherently their outputs react to changes in their inputs; such a generic concept is treated in the case of films comprising multilayers of tilted optical ...
  • Boshkayev, Kuantay; Luongo, Orlando; Muccino, Marco (EDP Sciences, 2020-10-19)
    We investigate neutrino oscillation in the field of an axially symmetric space-time, employing the so-called q-metric, in the context of general relativity. Following the standard approach, we compute the phase shift ...

    : In this report, an improvement of the electrical performance and stability of a silver nanowire (AgNW) transparent conductive coating (TCC) is presented. The TCC stability against oxidation is achieved by coating the ...
  • Boshkayev, Kuantay; Konysbayev, Talgar; Kurmanov, Ergali; Luongo, Orlando; Muccino, Marco (MDPI, 2020-10-22)
    We investigate the dark matter distribution in the spiral galaxy ESO0140040, employing the most widely used density profiles: the pseudo-isothermal, exponential sphere, Burkert, Navarro-Frenk-White, Moore and Einasto ...
  • Good, Michael R. R.; Ong, Yen Chin (SpringerOpen, 2020-12-21)
    The Reissner–Nordström black hole – moving mirror correspondence is solved. The beta coefficients reveal that charge makes a black hole radiate fewer particles (neutral massless scalars) per frequency. An old ...
  • Good, Michael R.R.; Ju´arez-Aubry, Benito A.; Moustos, Dimitris; Temirkhan, Maksat (Springer Verlag, 2020-06)
    We study the detailed balance temperatures recorded along all classes of stationary, uniformly accelerated worldlines in four-dimensional Minkowski spacetime, namely along (i) linear uniform acceleration, (ii) cusped, ...
  • Abdullaev, A.; Utegulov, Zhandos N.; Chauhan, Vinay S.; O’Connell, Jacques; Skuratov, Vladimir; Khafizov, M. (AIP Publishing, 2020-01-06)
    Anisotropic thermal transport behavior was investigated in a single crystal sapphire patterned by vertically aligned few-nanometer diameter and several micrometer long cylindrical ion tracks. These ion tracks were introduced ...
  • Beznosko, Dmitriy; Beisembaev, R. U.; Baigarin, Kanat; Batyrkhanov, Ayan; Beisembaeva, Elena; Beremkulov, Т.; Dalkarov, O.D.; Iakovlev, Alexander; Ryabov, Vladimir; Suleimenov, N. S.; Sadykov, Turlan; Tagay, Zhenisbek; Uakhitov, T.; Vildanova, M. I.; Zhukov, V. V. (IOP Publishing, 2020-01-01)
    Horizon-T is an innovative detector system constructed to study temporary structure of Extensive Air Showers (EAS) in the energy range above ~1016 eV coming from a wide range of zenith angles (up to 80°). The system, located ...

  • Nussupbekov, Ayan; Malafarina, Daniele (SpringerOpen, 2020-03-12)
    We consider the effects that modifications to general relativity (GR) at high densities may have on the structure of spherical compact objects. Such effects can be modeled via semi-classical corrections that are manifest ...
  • Juvela, Mika; Guillet, Vincent; Liu, Tie; Ristorcelli, Isabelle; Pelkonen, Veli-Matti; Alina, Dana; Bronfman, Leonardo; Eden, David J.; Kim, Kee Tae; Koch, Patrick M.; Kwon, Woojin; Lee, Chang Won; Malinen, Johanna; Micelotta, Elisabetta; Montillaud, Julien; Rawlings, Mark G.; Sanhueza, Patricio; Soam, Archana; Traficante, Alessio; Ysard, Nathalie; Zhang, Chuan-Peng (Astronomy & Astrophysics, 2018-11-23)
    Context. The sub-millimetre polarisation of dust emission from star-forming clouds carries information on grain properties and on the effects that magnetic fields have on cloud evolution. Aims. Using observations of a ...
  • Valagiannopoulos, Constantinos; Gangaraj, S Ali Hassani; Monticone, Francesco (Nanomaterials and Nanotechnology, 2018-09-03)
    Anomalous scattering effects (invisibility, superscattering, Fano resonances, etc) enabled by complex media and metamaterials have been the subject of intense efforts in the past couple of decades. In this article, we ...
