  • Genericity aspects in gravitational collapse to black holes and naked singularities 
    Joshi, Pankaj S.; Malafarina, D.; Saraykar, Ravindra V. (2012-07-04)
    We investigate here the genericity and stability aspects for naked singularities and black holes that arise as the final states for a complete gravitational collapse of a spherical massive matter cloud. The form of the ...
  • Geometric creation of quantum vorticity 
    Good, Michael R.R.; Xiong, Chi; Chua, Alvin J.K.; Huang, Kerson (2015)
    We consider superfluidity and quantum vorticity in rotating spacetimes. The system is described by a complex scalar satisfying a nonlinear Klein-Gordon equation. Rotation terms are identified and found to lead to the ...

  • Gravitational blueshift from a collapsing object 
    Kong, Lingyao; Malafarina, D.; Bambi, Cosimo (2014-12-22)
    We discuss a counterintuitive phenomenon of classical general relativity, in which a significant fraction of the radiation emitted by a collapsing object and detected by a distant observer may be blueshifted rather than ...
  • Gravitational Collapse of Inhomogenous Perfect Fluid 
    Satin, Seema; Malafarina, D.; Joshi, Pankaj S. (2014)
    We study the complete gravitational collapse of a class of inhomogeneous perfect fluid models obtained by introducing small radial perturbations in an otherwise homogeneous matter cloud. The key feature that we assume for ...
  • Gravitational collapse with tangential pressure 
    Malafarina, D.; Joshi, Pankaj S. (2011-05-06)
    Using the general formalism for spherical gravitational collapse developed in [1], we investigate here the final fate of a spherical distribution of a matter cloud, where radial pressures vanish but tangential pressures ...
  • GRAVITY WITH SCALAR FIELD VISCOUS FLUID 
    Myrzakul, S R; Imankul, M; Arzimbetova, M; Myrzakul, T R (Journal of Physics: Conference Series, 2021)
    We focus on a viable teleparallel cosmological model with a scalar field in a flat Friedman-Robertson-Walker universe. The Lagrangian and equations of motion are obtained. The case of an inhomogeneous viscous dark energy ...

    Bubin, Sergiy; Varga, Kalman (2011)
    Variational calculations of the ground state of positronium hydride (HPs) are reported, including various expectation values, electron-positron annihilation rates, and leading relativistic corrections to the total and ...
  • Group theory, entropy and the third law of thermodynamics 
    Canturk, Bilal; Oikonomou, Thomas; Bagci, G. Baris (Annals of Physics, 2017-02-01)
    Abstract Curado et al. (2016) have recently studied the axiomatic structure and the universality of a three-parameter trace-form entropy inspired by the group-theoretical structure. In this work, we study the group-theoretical ...
  • Guessing the Texture of Magnetic Samples Assisted by Aharonov-Bohm Effect 
    Valagiannopoulos, Constantinos; Alu, A.; Dimakis, A.; Marengo, E. A. (IEEE, 2016)
    Aharonov-Bohm (AB) effect is a very significant phenomenon of quantum mechanics. It demonstrates the significance of electromagnetic potentials (proportional to fluxes) against the electromagnetic fields through the ...
  • Highly selective transmission and absorption from metasurfaces of periodically corrugated cylindrical particles 
    Tagay, Zhenisbek; Valagiannopoulos, Constantinos (Physical review B, 2018-09-25)
    Gratings of infinite wires make, perhaps, the simplest class of metasurfaces, which, however, are utilized for a variety of different objectives in wave manipulation. Importantly, due to their analytical solvability, ...
