Strange warping geometry helps to push scientific boundaries

Atomic interactions in everyday solids and liquids are so complex that some of these materials' properties continue to elude physicists' understanding. Solving the problems mathematically is beyond the capabilities of modern ...

Unusual quantum state of matter observed for the first time

It's not every day that someone comes across a new state of matter in quantum physics, the scientific field devoted to describing the behavior of atomic and subatomic particles in order to elucidate their properties.

When is a coffee mug a donut? Topology explains it

A topologist is a person who cannot tell the difference between a coffee mug and a donut—so goes a joke about a little-known scientific field crowned Tuesday with a Nobel Physics Prize.

Scientists discover exotic quantum state at room temperature

For the first time, physicists have observed novel quantum effects in a topological insulator at room temperature. This breakthrough, published as the cover article of the October issue of Nature Materials, came when Princeton ...

New physics in iridium compounds

(—Unraveling the complexities of spin-orbital coupling could someday lead to new high-temperature superconductors and workable quantum computers via an elusive phase of matter called a "quantum spin liquid." Two ...
