Supersymmetry of Frw Barotropic Cosmologies
Barotropic FRW cosmologies are presented from the standpoint of nonrelativistic supersymmetry. First, we reduce the barotropic FRW system of differential equations to simple harmonic oscillator differential equations. Employing the factorization procedure, the solutions of the latter equations are divided into the two classes of bosonic (nonsingular) and fermionic (singular) cosmological soluti...
متن کاملDirac-like Equations for Barotropic Frw Cosmologies
where a is the scale factor of the universe, ρ and p are the energy density and the pressure, respectively, of the perfect fluid of which a classical universe is usually assumed to be made of, κ = 0,±1 is the curvature index of the flat, closed, open universe, respectively, and γ is the constant adiabatic index of the cosmological fluid. Recently, Faraoni, proposed the “Riccati route” of solvin...
متن کاملKdV ADIABATIC INDEX SOLITONS IN BAROTROPIC OPEN FRW COSMOLOGIES
for the log derivative of the FRW scale factor, the famous Hubble parameterH(η) = da/dη a . The independent variable is the conformal time η, c is simply related to the adiabatic index of the cosmological fluid, c = 3 2 γ − 1 which was assumed constant by Faraoni, and κ = 0,±1 is the curvature index of the flat, closed, open FRW universe, respectively. For the mathematical considerations of thi...
متن کاملShifted Riccati Procedure: Application to Conformal Barotropic FRW Cosmologies
In the case of barotropic FRW cosmologies, the Hubble parameter in conformal time is the solution of a simple Riccati equation of constant coefficients. We consider these cosmologies in the framework of nonrelativistic supersymmetry that has been effective in the area of supersymmetric quantum mechanics. Recalling that Faraoni [Amer. J. Phys. 67 (1999), 732–734] showed how to reduce the barotro...
متن کاملAnalogue Models for Frw Cosmologies
It is by now well known that various condensed matter systems may be used to mimic many of the kinematic aspects of general relativity, and in particular of curved-spacetime quantum field theory. In this essay we will take a look at what would be needed to mimic a cosmological spacetime — to be precise a spatially flat FRW cosmology — in one of these analogue models. In order to do this one nee...
