Unified approach to study quantum properties of primordial black holes, wormholes and of quantum cosmology

Primordial Black Holes as a Probe of Cosmology and High Energy Physics

Recent developments in the study of primordial black holes (PBHs) will be reviewed, with particular emphasis on their formation and evaporation. PBHs could provide a unique probe of the early Universe, gravitational collapse, high energy physics and quantum gravity. Indeed their study may place interesting constraints on the physics relevant to these areas even if they never formed.

Formation of MACHO-Primordial Black Holes in Inflationary Cosmology

As a nonbaryonic explanation of massive compact halo objects, a phenomenological model is presented which predicts formation of primordial black holes at a desired mass scale. The required feature of initial density fluctuation is realized making use of the primordially isocurvature fluctuation generated in an inflationary universe model with multiple scalar fields.

Classical and Quantum Aspects of Radiation Uid Shells: Black Holes and Wormholes, Mass Ampliication, Light Dark Matter

A spherically symmetric thin shell out of the matter satisfying the ultrarelativistic state equation (radiation uid) is considered. Description of black holes and traversable wormholes formed by such shells is given. We prove the theorem on the static states of shells of these types. The motivation of classical wormholes instability and restriction on the total energy becomes the corollary of t...
