(Phys.org)—There are many different ways to generate a hologram, each with its own advantages and disadvantages. Trying to maximize the advantages, researchers in a new study have designed a hologram made of a metamaterial ...
Naoto Nagaosa and Bohm-Jung Yang from the RIKEN Center for Emergent Matter Science and co-workers have discovered a previously unknown state of matter that can occur when matter switches from one exotic quantum state to another ...

(Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in ...
When matter changes from solids to liquids to vapors, the changes are called phase transitions. Among the most interesting types are more exotic changes—quantum phase transitions—where the strange properties of quantum ...
