Description
We will calculate the pressure and the energy density of a cold and dilute gas, where the particles of gas are coupled to a scalar field. The arising Yukawa potential between the particles determines the energy density and pressure of the gas. The finite density of gas modifies the propagator of the scalar field and thereof the mass term in the Yukawa potential depends on the density of gas. We will show that due to the Anderson localization the gas has the equation of state of Dark Energy (DE), ω=−1, in cosmology. We will give a relation between the energy density and the quantum parameters of the model. In conclusion, the model can explain the accelerated expansion of the Universe and it relates the scale of observed DE to a new scale of particle physics.
