Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing
attention to Einstein's other theory of gravity. In this Review, we give a comprehensive …

This article will review quantum particle creation in expanding universes. The emphasis will
be on the basic physical principles and on selected applications to cosmological models …

The standard model of hot big-bang cosmology requires initial conditions which are
problematic in two ways:(1) The early universe is assumed to be highly homogeneous, in …

Nature's simplest field, the scalar field, has been the protagonist of physical theories for a
long time. Even before the publication of the theory of general relativity G. Nordström …

Bringing together the key ideas from nonequilibrium statistical mechanics and powerful
methodology from quantum field theory, this 2008 book captures the essence of …

This book introduces the general theory of relativity and includes applications to cosmology.
The book provides a thorough introduction to tensor calculus and curved manifolds. After the …

Whereas semiclassical gravity is based on the semiclassical Einstein equation with sources
given by the expectation value of the stress-energy tensor of quantum fields, stochastic semi …

It is argued that a new inflationary universe scenario, which provides a possible solution of
the horizon, flatness, homogeneity, isotropy and primordial monopole problems, can be …

Some properties of cosmological models with matter creation are investigated in the
framework of the Friedmann-Robertson-Walker line element. For adiabatic matter creation …

We continue our earlier investigation of the back reaction problem in semiclassical gravity
with the Schwinger-Keldysh or closed-time-path (CTP) functional formalism using the …
