The gapless fermionic excitations in superfluid3He-A have the “relativistic” spectrum close to the gap nodes. This allowed us to model the modern cos-mological scenaria of baryogenesis and magnetogenesis. The same massless fermions induce another low-energy property of the quantum vacuum – the gravitation. The effective metric of the space, in which the free quasiparticles move along geodesies, is not generally flat. Different order parameter textures correspond to curved effective space and… 
Quantum Gravity as a Fermi Liquid
We present a reformulation of loop quantum gravity with a cosmological constant and no matter as a Fermi-liquid theory. When the topological sector is deformed and large gauge symmetry is broken, we
Energy-momentum tensor of quasiparticles in the effective gravity in superfluids.
The problem of the energy-momentum conservation for matter in the gravitational field is discussed on the example of the effective gravity, which arises in superfluids. The ”gravitational” field
Probing semiclassical analog gravity in Bose-Einstein condensates with widely tunable interactions
Bose-Einstein condensates BEC’s have recently been the subject of considerable study as possible analog models of general relativity. In particular it was shown that the propagation of phase
Aspects of cosmic inflation in expanding Bose?Einstein condensates
Phonons in expanding Bose-Einstein condensates with wavelengths much larger than the healing length behave in the same way as quantum fields within a universe undergoing an accelerated expansion.
Aspects of Quantum Fluctuations under Time-dependent External Influences
The vacuum of quantum field theory is not empty space but filled with quantum vacuum fluctuations, which give rise to many intriguing effects. The first part of this Thesis addresses cosmic
Quantum field theory in curved space-time and analogue gravity in Bose-Einstein condensates
In this thesis we present studies on both quantum field theory in curved spacetimes and related analogue models of gravity in Bose-Einstein Condensates (BEC). In 1981, Unruh observed that the
A Generalization of the Lorentz Ether to Gravity with General-Relativistic Limit
Does relativistic gravity provide arguments against the existence of a preferred frame? Our answer is negative. We define a viable theory of gravity with preferred frame. In this theory, the EEP
Dirac Equation in (1+1)-Dimensional Curved Spacetime and the Multiphoton Quantum Rabi Model.
TLDR
It is shown that gravity generates squeezing of the Dirac particle wave function from the duality between the squeezing term in the multiphoton QRM and the metric coupling in the DCS.
Analogue 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
Black hole entropy in induced gravity: Reduction to 2D quantum field theory on the horizon
It is argued that degrees of freedom responsible for the Bekenstein-Hawking entropy of a black hole in induced gravity are described by two dimensional quantum field theory defined on the bifurcation
