Theorists describe the two-layer system as a Josephson junction, an exciton condensate, or a ferromagnet.
How well does CP violation obey standard particle theory? Electron-positron colliders of a new kind were built in the US and Japan to find out.
Search and Discovery
Now that researchers have observed the condensation of a gas of helium in its metastable state, helium is the first atom to form a Bose condensate in two phases.
Issues and Events
In the debates on how to reform Europe’s higher education systems, the aims are faster, internationally recognized degrees that will be accepted by employers, increased flexibility of study programs, and global competitiveness.
US physics departments are starting to take measures to select students who are more dedicated to staying in physics.
Once studied primarily for their effects on light, thin magnetic films are today being layered to make complex structures with unique magnetic properties. Devices based on these structures are revolutionizing electronic data storage.
Nanometer-scale islands that form spontaneously on a semiconductor substrate have atomlike properties and potential applications in optical and optoelectronic devices, quantum computing, and information storage.
