Researchers in Singapore have built a refrigerator that's just three atoms big. This quantum fridge won't keep your drinks cold, but it's cool proof of physics operating at the smallest scales.  Researchers have created a new testing ground for quantum systems in which they can literally turn certain particle interactions on and off, potentially paving the way for advances in spintronics.  In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion.  Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons.  They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids.
