چکیده
We present cosmological perturbation theory in mass varying neutrino models, and calculate cosmic microwave background anisotropies and matter power spectrum. In these models, the evolution of the mass of neutrinos is determined by the quintessence scalar field, which is responsible for the cosmic acceleration today. We consider several types of scalar field potentials and put constraints on the coupling parameter between neutrinos and dark energy.

The central claim that understanding quantum mechanics requires a conscious observer, which is made made by B. Rosenblum and F. Kuttner in their book ”Quantum Enigma: Physics encounters consciousnes”, is shown to be based on various misunderstandings and distortions of the foundations of quantum mechanics.

We present a systematic semiclassical procedure to compute the partition function for scalar field theories at finite temperature. The central objects in our scheme are the solutions of the classical equations of motion in imaginary time, with spatially independent boundary conditions. Field fluctuations – both field deviations around these classical solutions, and fluctuations of the boundary ...
