The mechanisms which give rise to Hawking radiation are revealed by analyzing in detail
pair production in the presence of horizons. In preparation for the black hole problem, three …

We present a new avenue to black hole evaporation using a heat-kernel approach
analogous as for the Schwinger effect. Applying this method to an uncharged massless …

The purpose of this paper is to review relativistic quantum theories with an invariant
evolution parameter. Parametrized relativistic quantum theories (PRQT) have appeared …

In the space-dependent gauge, each mode of the Klein-Gordon equation in a strong electric
field takes the form of a time-independent Schrödinger equation with a potential barrier. We …

A bstract We study the Schwinger mechanism by a uniform electric field in dS 2 and AdS 2
and the curvature effect on the Schwinger effect, and further propose a thermal interpretation …

In analyzing the nature of thermal radiance experienced by an accelerated observer (Unruh
effect), an eternal black hole (Hawking effect), and in certain types of cosmological …

We compute the corrections to the transition amplitudes of an accelerated Unruh “box” that
arise when the accelerated box is replaced by a “two level ion” immersed in a constant …

We consider charged boson stars and study their effect on the structure of the vacuum. For
very compact particle like “stars”, with constituent mass m∗ close to the Planck mass m Pl, ie …

Pair creation in an external electric field is presented in terms of the localized events which
contribute to the mean current that is produced. Each of these localized contributions is …

We extend the discussion of the antipodal identification of black holes to the Reissner–
Nordström (RN) spacetime by develo** the classical tools necessary to define the …
