Description
We demonstrate that the simplest three-dimensional superflow of logarithmic quantum Bose liquid can generate a four-dimensional relativistic quinton system, which comprises the dilaton and a combination of quintessence and the tachyonic phantom; the last two being non-minimally coupled to each other. Both gravity and these scalar fields are thus shown to be "infrared" projections of the dynamical evolution of superfluid vacuum density and its fluctuations onto the measuring apparatus of a relativistic observer. The unified model describes the transition from the inflationary epoch in the early universe to the contemporary accelerating expansion of the universe, commonly referred to as the 'dark energy' period.
In the second part of the talk we will reflect on the era preceding the inflationary epoch. Our conjecture is that the newly formed background matter was in a quantum superposition of its states, which created the primordial multiverse with uncertain spacetime geometry, akin to the Schrodinger's cat paradox. Fortunately, at a certain moment in time, the measurement event occurred (probably the first one ever), which broke the superposition and reduced that multiverse to one state, the Universe, to further evolve as discussed in the first part of my talk. We demonstrate that this measurement can be described via the quantum information extraction process, whose description naturally involves quantum Shannon entropy and requires logarithmic nonlinearity in the quantum evolution equations. The background matter thus became the logarithmic quantum liquid and superfluid and formed what we call now the physical vacuum.
