  • 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 ...

  • Boshkayev, Kuantay; Quevedo, Hernando; Nurbakyt, Gulmira; Malybayev, Algis; Urazalina, Ainur (MDPI, 2019-10)
    In this work, we investigate the correspondence between the Erez–Rosen and Hartle–Thorne solutions. We explicitly show how to establish the relationship and find the coordinate transformations between the two metrics. For ...
  • Boshkayev, Kuantay; D'Agostino, Rocco; Luongo, Orlando (Springer, 2019-04)
    We study extended classes of logotropic fluids as unified dark energy models. Under the hypothesis of the Anton–Schmidt scenario, we consider a universe obeying a single fluid model with a logarithmic equation of state. ...

    The giant tortoise coordinate is a moving mirror inspired generalization of the ReggeWheeler counterpart that demonstrates a unitary evaporating black hole emitting a total finite energy.
  • Hornyak, Istvan; Adamowicz, Ludwik; Bubin, Sergiy (American Physical Society, 2019-09-04)
    Benchmark calculations of the total and transition energies of the four lowest S1 states of the beryllium atom are performed. The computational approach is based on variational calculations with finite mass of the nucleus. ...
