Reaching superconductivity layer by layer

Imagine a sheet of material just one layer of atoms thick—less than a millionth of a millimeter. While this may sound fantastical, such a material exists: it is called graphene and it is made from carbon atoms in a honeycomb ...

Physicists realize fractionalization without a magnetic field

On the dream list of many condensed matter physicists is observing fractionalization, the phenomena of a collective state of electrons carrying a charge that is a fraction of the electron charge, without a magnetic field.
