Graduate student Lee Liu and members of Prof. Kang-Kuen Ni's group have combined two atoms for the first time into what researchers call a dipolar molecule. The work is described in a new paper published in Science...
         
The copper oxide-based high-temperature superconductors display a mysterious "pseudogap" metal phase at temperatures just above the critical temperature in a regime of low hole density. Extensive experimental and numerical studies have yielded much information on the nature of the electron corrections...

Physicists have shown that when two sheets of graphene are misaligned at a so-called magic angle of approximately 1.1°, the two-layer stack becomes a superconductor...
