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

There is accumulating evidence that (fundamental) scalar fields may exist in nature. The
gravitational collapse of such a boson cloud would lead to a boson star (BS) as a new type …

We observe spontaneous Hawking radiation, stimulated by quantum vacuum fluctuations,
emanating from an analogue black hole in an atomic Bose–Einstein condensate …

Can high-energy physics be simulated by low-energy, non-relativistic, many-body systems
such as ultracold atoms? Such ultracold atomic systems lack the type of symmetries and …

By a combination of quantum field theory and general relativity, black holes have been
predicted to emit Hawking radiation. Observation from an actual black hole is, however …

We consider the possibility that the dark matter which is required to explain the dynamics of
the neutral hydrogen clouds at large distances from the galactic centre could be in the form …

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 …

Physicists are pondering on the possibility of simulating black holes in the laboratory by
means of various “analog models”. These analog models, typically based on condensed …

Atomic gases confined in curved geometries are characterized by distinctive features that
are absent in their flat counterparts, such as periodic boundaries, local curvature and …

It is demonstrated that gravity waves of a flowing fluid in a shallow basin can be used to
simulate phenomena around black holes in the laboratory. Since the speed of the gravity …
