Abstract In a modern viewpoint relativistic quantum field theory is an emergent phenomenon arising in the low-energy corner of the physical fermionic vacuum – the medium, whose nature remains unknown. The same phenomenon occurs in condensed matter systems: In the extreme limit of low-energy condensed matter systems of special universality class acquire all the symmetries, which we know today in high-energy physics: Lorentz invariance, gauge invariance, general covariance, etc. The chiral fermions as well as gauge bosons and gravity field arise as fermionic and bosonic collective modes of the system. Inhomogeneous states of the condensed matter ground state – vacuum – induce nontrivial effective metrics of the space, where the free quasiparticles move along geodesics. This conceptual similarity between condensed matter and the quantum vacuum allows us to simulate many phenomena in high-energy physics and cosmology, including the axial anomaly, baryoproduction and magnetogenesis, event horizon and Hawking radiation, cosmological constant and rotating vacuum, etc., probing these phenomena in ultra-low-temperature superfluid helium, atomic Bose condensates and superconductors. Some of the experiments have been already conducted.

Analogue Models of and for Gravity (2001, background): “Though the situation is still far from clear, interest in these possibilities is both long-standing (see for instance the sub-manifold models in references [37, 38]) and ongoing [31, 34, 39, 40].”
How far are we from the quantum theory of gravity (2003, background): “Recently several condensed matter physicists have proposed that quantum spacetime may be modeled in terms of an ordinary quantum statistical system such as a fermi liquid[206, 207, 208].”
Analogue Gravity (2005, background): “That year also marked the appearance of a review article on superfluid analogues [406], more work on “near-horizon” physics [124], and the transference of the idea of analogue-inspired “multiple metric” theories into cosmology where they can be used as the basis for a precise definition of what is m”
