University of Tokyo researchers have announced a new approach for electrical cooling without the need for moving parts.  When electrons that repel each other are confined to a small space, they can form an ordered crystalline state known as a Wigner crystal.  A new experiment that tests the limit of how large an object can be before it ceases to behave quantum mechanically has been proposed by physicists in the UK and India.  Phonons are discrete units of vibrational energy predicted by quantum mechanics that correspond to collective oscillations of atoms inside a molecule or a crystal.  This achievement is considered as an important landmark for the realization of practical application of photon upconversion technology.
