Vacuum energy: quantum hydrodynamics vs quantum gravity
We compare quantum hydrodynamics and quantum gravity. They share many common features, both have quadratic divergences, and both lead to the problem of the vacuum energy, which in the quantum gravity transforms to the cosmological constant problem. We show that in quantum liquids the vacuum energy density is not determined by the quantum zero-point energy of the phonon modes. The vacuum energy ...
متن کاملFrom Quantum Hydrodynamics to Quantum Gravity
In the presentations at the Session ‘Analog Models of and for General Relativity’ at 11 Marcel Grossmann Meeting, general relativity has been considered as emergent phenomenon. General approaches to emergent relativity have been analyzed. Particular example when gravity is induced in the low-energy corner of quantum condensed matter of the proper universality class has been presented. It was su...
متن کاملQuantum hydrodynamics: Well-posedness and asymptotics
In this talk, we consider the recent results on well-posedness and small asymptotic analysis on the quantum hydrodynamic model which takes the form of Euler-Poisson with dispersion.
متن کاملHydrodynamics for Quasi-Free Quantum Systems
We consider quasi-free quantum systems and we derive the Euler equation using the so-called hydrodynamic limit. We use Wigner’s well-known distribution function and discuss an extension to band distribution functions for particles in a periodic potential. We investigate the Bosonic system of hard rods and calculate fluctuations of the density.
متن کاملClassicality via hydrodynamics in quantum field theory
Motivated by ideas from the consistent histories approach to quantum mechanics, we examine a simple model of hydrodynamic coarse graining for a scalar field. It consists in averaging the field over spatial regions of size L and constructing the evolution equations for the coarse grained quantities, identifying dissipation and noise.
