Stretched exponential relaxation in the Coulomb glass
The relaxation of the specific heat and the entropy to their equilibrium
values is investigated numerically for the three-dimensional Coulomb glass at
very low temperatures. The long time relaxation follows a stretched exponential
function, , with the exponent increasing
with the temperature. The relaxation time follows an Arrhenius behavior
divergence when . A relation between the specific heat and the entropy
in the long time regime is found.Comment: 5 pages and 4 figure
The entangled accelerating universe
Using the known result that the nucleation of baby universes in correlated
pairs is equivalent to spacetime squeezing, we show in this letter that there
exists a T-duality symmetry between two-dimensional warp drives, which are
physically expressible as localized de Sitter little universes, and two
dimensional Tolman-Hawking and Gidding-Strominger baby universes respectively
correlated in pairs, so that the creation of warp drives is also equivalent to
spacetime squeezing. Perhaps more importantly, it has been also seen that the
nucleation of warp drives entails a violation of the Bell's inequalities, and
hence the phenomena of quantum entanglement, complementarity and wave function
collapse. These results are generalized to the case of any dynamically
accelerating universe filled with dark or phantom energy whose creation is also
physically equivalent to spacetime squeezing and to the violation of the Bell's
inequalities, so that the universe we are living in should be governed by
essential sharp quantum theory laws and must be a quantum entangled system
