Abstract

We study the Vaidya black hole surrounded by
the exotic quintessence-like, phantom-like and cosmological
constant-like fields by means of entropic considerations.
Explicitly,we showthat for this thermodynamical system, the
requirement of the identification of the D-bound and Bekenstein
entropy bound can be considered as a thermodynamical
criterion by which one can rule out the quintessence-like and
phantom-like fields, and prefer the cosmological constant as
a viable cosmological field.
