Supercooled first order phase transitions are typical of theories where conformal symmetry is predominantly spontaneously broken. In these the fate flat scalar direction highly sensitive to size and scaling dimension explicit breaking deformations. For a given deformation, coupling must lie in particular region realize supercooled transition. We identify supercooling window weakly coupled deriv...

The effectiveness of static magnetic fields (SMFs) in improving food freezing is a topic that, nowadays, raises substantial controversy among the scientific community. To shed light on this matter, new experiments, under well controlled conditions, were performed potato samples subjected or not to SMFs either 40–55 mT 150–200 mT, that is, approximately 1000 and 5000 times greater than Earth's f...

We describe the behavior m directional solidification of the faceted smectic-A smectic-B interface of 408 (butyloxybenzihdene octylaniline) Above the onset of instability, which is given by the classical constitutional-supercooling cntenon, we observe the nucleation of macrosteps Several mechanisms are possible, depending on the velocity These macrosteps are always unstable and propagate along ...

We investigate laser cooling of an ensemble of atoms in an optical cavity. We demonstrate that when atomic dipoles are synchronized in the regime of steady-state superradiance, the motion of the atoms may be subject to a giant frictional force leading to potentially very low temperatures. The ultimate temperature limits are determined by a modified atomic linewidth, which can be orders of magni...

We review the Kauzmann paradox and what it implies about the configuration space energy hypersurface for "structural glassformers." With this background, we then show how the relaxation expression of Adam and Gibbs qualitatively accounts for most of the phenomenology of liquid and polymeric glassformers including the strong/fragile liquid pattern, and the behavior of non-ergodic systems. Extend...
