Abstract

Quantum excitations or quasiparticles in a material, like for example phonons in a Bose-Einstein condensate, or fermions in the vicinity of a Dirac point in materials like graphene, can be subject to non-trivial spacetime geometries that differ from the Minkowski spacetime of the laboratory. These geometries are determined by material properties like the speed of sound, fluid velocity, or Fermi velocity, and they can depend themselves on space and time. Geometries of this kind are emergent in the sense that they appear in the low energy sector of macroscopic pieces of matter consisting of many atoms or other constituents. The talk reviews this physics and discusses how it allows quantum simulation of quantum fields in curved spacetime, as it plays a role for example in the early universe.
