Cosmological Implications of a Lorentz Invariance Violating O(2) Model [PDF]
A. JahanWe derive the free energy of a Lorentz invariance violating (LIV) O(2) model, for which a non-vanishing commutator among it's momenta is supposed. Then we investigate the possible implications of such a matter field on the time evolution of a flat FRW universe at low and high temperatures.View original: http://arxiv.org/abs/1210.2513
