Analogue Gravity
Analogue gravity is a research programme which investigates analogues of general relativistic gravitational fields within other physical systems, typically but not exclusively condensed matter systems, with the aim of gaining new insights into their corresponding problems. Analogue models of (and for) gravity have a long and distinguished history dating back to the earliest years of general rel...
متن کاملAnalogue gravity from Bose–Einstein condensates
We analyse prospects for the use of Bose–Einstein condensates as condensedmatter systems suitable for generating a generic ‘effective metric’, and for mimicking kinematic aspects of general relativity. We extend the analysis due to Garay et al (2000 Phys. Rev. Lett. 85 4643, 2001 Phys. Rev. A 63 023611). Taking a long-term view, we ask what the ultimate limits of such a system might be. To this...
متن کاملAnalogue gravity from field theory normal modes?
We demonstrate that the emergence of a curved spacetime ‘effective Lorentzian geometry’ is a common and generic result of linearizing a classical scalar field theory around some non-trivial background configuration. This investigation is motivated by considering the large number of ‘analogue models’ of general relativity that have recently been developed based on condensedmatter physics, and as...
متن کاملAnalogue models of and for gravity
Condensed matter systems, such as acoustics in flowing fluids, light in moving dielectrics, or quasiparticles in a moving superfluid, can be used to mimic aspects of general relativity. More precisely these systems (and others) provide experimentally accessible models of curvedspace quantum field theory. As such they mimic kinematic aspects of general relativity, though typically they do not mi...
متن کاملAnalogue model for quantum gravity phenomenology
So called “analogue models” use condensed matter systems (typically hydrodynamic) to set up an “effective metric” and to model curved-space quantum field theory in a physical system where all the microscopic degrees of freedom are well understood. Known analogue models typically lead to massless minimally coupled scalar fields. We present an extended “analogue space-time” programme by investiga...
