Contest between superconductivity and insulating states in Magic Angle Graphene

Researchers develop a set of entirely novel knobs to control correlated electrons and demonstrate that superconductivity can exist without insulating phases in Magic Angle Twisted Bi-layer Graphene.

Atomic 'Swiss Army Knife' precisely measures materials for quantum computers

Scientists have developed a novel instrument that can make three kinds of atom-scale measurements simultaneously: It images single atoms. It maps atomic-scale hills and valleys on metal and insulating surfaces. And it records the flow of current across atom-thin materials subject to giant magnetic fields.

Limitations of super-resolution microscopy overcome

The smallest cell structures can now be imaged even better: The combination of two microscopy methods makes fluorescence imaging with molecular resolution possible for the first time.

Excitation of robust materials

Physics team observed extremely fast electronic changes in real time in a special material class.

When imaging atoms, blurrier is better

Scientists have developed a new form of ptychography that uses complex algorithms to achieve faster, more efficient imaging with picometer (one-trillionth of a meter) precision that won?t damage samples so easily.
