Quasinormal modes of the Dirac field in the novel 4D Einstein-Gauss-Bonnet gravity
M. S. Churilova
While quasinormal modes of bosonic fields for the non-trivial -dimensional Einstein-Gauss-Bonnet theory of gravity suggested in [D.~Glavan and C.~Lin, Phys.\ Rev.\ Lett.\ {\bf 1…
Quasinormal modes of the test fields in the novel 4D Einstein-Gauss-Bonnet-de Sitter gravity
M. S. Churilova
The regularization proposed in [D.~Glavan and C.~Lin, Phys.\ Rev.\ Lett.\ {\bf 124}, 081301 (2020)] led to the black hole solutions which turned out to be the solutions of the cons…
Non-evident stability of a Dirac field in Schwarzschild-de Sitter spacetime
R. A. Konoplya, M. S. Churilova
Perturbations of the Dirac field in the Schwarzschild spacetime are characterized by two wave equations (for two chiralities) with effective potentials which are iso-spectral and o…
Accelerated expansion of the universe from the perspective of inhomogeneous cosmology
I. Bormotova, E. Kopteva, M. Churilova +1
We present a special case of the Stephani solution with spherical symmetry while considering different values of spatial curvature. We investigate the dynamics of the universe evol…
Black holes in Einstein-aether theory: Quasinormal modes and time-domain evolution
M. S. Churilova
We propose accurate calculations of quasinormal modes of black holes in the Einstein-aether theory, which were previously considered in the literature, partially, with insufficient…
Accelerated Expansion of the Universe in the Model with Non-Uniform Pressure
Elena Kopteva, Irina Bormotova, Maria Churilova +1
We present the particular case of the Stephani solution for shear-free perfect fluid with uniform energy density and non-uniform pressure. Such models appeared as possible alternat…
