  • ANALYTICAL INVERSE DESIGN OF POLARIZATION-INSENSITIVE PHOTONIC FILTERS BY TAILORING FABRY-PEROT INTERFERENCE 
    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 ...
  • DISPERSION RELATIONS IN FINITE-BOOST DSR 
    Jafari, Nosratollah; Good, Michael R.R. (Elsevier, 2020-10-10)
    We find finite-boost transformations DSR theories in first order of the Planck length , by solving differential equations for the modified generators. We obtain corresponding dispersion relations for these transformations, ...
  • MODIFIED SCHWARZSCHILD METRIC FROM A UNITARY ACCELERATING MIRROR ANALOG 
    Good, Michael R.R.; Linder, Eric V. (IOP Publishing Ltd, 2021-04-02)
    We present a modified Schwarzschild solution for a model of evaporation of a black hole with information preservation. By drawing a direct analogy to the quantum pure accelerating mirror (dynamical Casimir effect of a 1D ...
  • MOTION OF SPINNING PARTICLES IN NON ASYMPTOTICALLY FLAT SPACETIMES 
    Toshmatov, Bobir; Rahimov, Ozodbek; Ahmedov, Bobomurat; Malafarina, Daniele (Springer Verlag, 2020-07)
    The assumption of asymptotic flatness for isolated astrophysical bodies may be considered an approximation when one considers a cosmological context where a cosmological constant or vacuum energy is present. In this framework ...
  • NEUTRINO OSCILLATION IN THE Q-METRIC 
    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 ...
  • ON THE PROPERTIES OF A DEFORMED EXTENSION OF THE NUT SPACE-TIME 
    Narzilloev, Bakhtiyor; Malafarina, Daniele; Abdujabbarov, Ahmadjon; Bambi, Cosimo (Springer Verlag, 2020-08)
    We consider a class of space-times given by a stationary extension of the Zipoy–Voorhees metric that was found by Halilsoy. We show that the solutions do not describe rotating sources but must be interpreted, similarly to ...
  • A TOY MODEL FOR A BABY UNIVERSE INSIDE A BLACK HOLE 
    Chakrabarty, Hrishikesh; Abdujabbarov, Ahmadjon; Malafarina, Daniele; Bambi, Cosimo (Springer Verlag, 2020-05)
    We present a dynamical toy model for an expanding universe inside a black hole. The model is built by matching a spherically symmetric collapsing matter cloud to an expanding Friedmann–Robertson–Walker universe through a ...
  • UNIAXIAL FILMS OF MAXIMALLY CONTROLLABLE RESPONSE UNDER VISIBLE LIGHT 
    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 ...
