  • 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 ...
  • NEUTRINO OSCILLATION IN THE Q-METRIC 
    Boshkayev, Kuantay; Luongo, Orlando; Muccino, Marco (EDP Sciences, 2020-10-19)

  • PARTICLE SPECTRUM OF THE REISSNER–NORDSTRÖM BLACK HOLE 
    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 ...

  • Note on the mass–radius relations for spherical compact objects in general relativity with semi-classical corrections 
    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 ...
