Abstract: We obtain the non-linear relation between cosmological density and velocity perturbations by examining their joint dynamics in a two-dimensional density–velocity divergence phase space. We ...

Abstract: Using a unique referencing technique, the signal decay of thin-film media is studied as a function of recorded linear density and temperature with great precision. It is found that the ...

Understanding the origin of the dramatic temperature and density dependence of the relaxation time of glass-forming liquids is a fundamental challenge in glass science. The recently established ...
