    • Abstract

       

      We consider the effect of quantizing the homogeneous mode of a scalar field on inflation. It is shown that any semiclassical description of the scalar field is bound to lead to density inhomogeneities which are unacceptably large.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
