Analogue gravity is a research programme which investigates analogues of general
relativistic gravitational fields within other physical systems, typically but not exclusively …

We review the present status of black hole thermodynamics. Our review includes discussion
of classical black hole thermodynamics, Hawking radiation from black holes, the generalized …

It is a deceptively simple question to ask how acoustic disturbances propagate in a non-
homogeneous flowing fluid. Subject to suitable restrictions, this question can be answered …

In most current models of inflation based on a weakly self-coupled scalar matter field
minimally coupled to gravity, the period of inflation lasts so long that, at the beginning of the …

Spacetimes with horizons show a resemblance to thermodynamic systems and it is possible
to associate the notions of temperature and entropy with them. Several aspects of this …

Traversable wormholes necessarily require violations of the averaged null energy condition,
this being the definition of “exotic matter.” However, the theorems which guarantee the …

Publisher Summary This chapter describes the geometry of light and the concepts of
transformation optics. Transformation optics is beginning to transform optics. The chapter …

We have created an analog of a black hole in a Bose-Einstein condensate. In this sonic
black hole, sound waves, rather than light waves, cannot escape the event horizon. A …

We measured the power spectrum and two-point correlation function for the randomly
fluctuating free surface on the downstream side of a stationary flow with a maximum Froude …
