    Horizon - T is a n innovative detector system constructed to study Extensive Air Showers (EAS) in the energy range above 10 16 eV coming from a wide range of zenith angles (0 o - 85 o ). The system ...
  • The instability of black hole formation in gravitational collapse 
    Joshi, Pankaj S.; Malafarina, D. (2011-01-11)
    We consider here the classic scenario given by Oppenheimer, Snyder, and Datt, for the gravitational collapse of a massive matter cloud, and examine its stability under the introduction of small tangential stresses. We show, ...
  • Theoretical concepts of unlimited-power reflectors, absorbers, and emitters with conjugately matched layers 
    Valagiannopoulos, Constantinos; Tretyakov, Sergei A. (American Physical Society, 2016-09-12)
    Recently, it was shown that by using special artificial materials it is possible to ensure that all electromagnetic modes of free space are conjugately matched to the modes of a material body and, thus, all modes deliver ...

    The variational method complemented with the use of explicitly correlated Gaussian basis functions is one of the most powerful approaches currently used for calculating the properties of few-body systems. Despite its ...
  • Thermodynamics and gravitational collapse 
    Malafarina, D.; Joshi, Pankaj S. (2011-06-19)
    It is known now that a typical gravitational collapse in general relativity, evolving from regular initial data and under physically reasonable conditions would end in either a black hole or a naked singularity final state. ...
