Inflationary RSII Model with a Matter in the Bulk and Exponential Potential of Tachyon Field
Marko Stojanović, Neven Bilić, Dragoljub D. Dimitrijević +2
In this paper we study a tachyon cosmological model based on dynamics of a 3-brane in the second Randall-Sundrum (RSII) model extended to include matter in the bulk. The presence o…
Planar Black holes and Entanglement Entropy in Analog Gravity Models
Neven Bilić, Tobias Zingg
Via constructing an explicit Lagrangian for which the perturbation equations are analogues of a scalar field propagating in a planar black hole space-time, it is found that all pla…
Numerical Calculation of Hubble Hierarchy Parameters and Observational Parameters of Inflation
Milan Milošević, Neven Bilić, Dragoljub D. Dimitrijević +2
We present results obtained by a software we developed for computing observational cosmological inflation parameters: the scalar spectral index () and the tensor-to-scalar rat…
Analog gravity in nonisentropic fluids
Neven Bilić, Hrvoje Nikolić
The analog acoustic metric has been originally derived for adiabatic acoustic perturbations propagating in an isentropic irrotational ideal fluid. In the framework of a Lagrangian…
Tachyon with an inverse power-law potential in a braneworld cosmology
Neven Bilić, Silvije Domazet, Goran S. Djordjevic
We study a tachyon cosmological model based on the dynamics of a 3-brane in the bulk of the second Randall-Sundrum model extended to more general warp functions. A well known proto…
Note on the thermodynamics and the speed of sound of a scalar field
Oliver F. Piattella, Júlio C. Fabris, Neven Bilić
We investigate the correspondence between a perfect fluid and a scalar field and show a possible way of expressing thermodynamic quantities such as entropy, particle number density…
Ghost Condensate Busting
Neven Bilić, Gary B. Tupper, Raoul D. Viollier
Applying the Thomas-Fermi approximation to renormalizable field theories, we construct ghost condensation models that are free of the instabilities associated with violations of th…
