A powerful guiding principle for topological quantum synthesis

Topological materials can be classified into topological insulators (TIs), topological crystalline insulators, topological Dirac semimetals, topological Weyl semimetals, topological nodal-line semimetals, and others. Such ...

Changing the color of laser light on the femtosecond time scale

How can the color of laser light be changed? One popular method to achieve this is the so-called second harmonic generation (SHG) effect, which doubles the frequency of light and hence changes its color. However, observing ...

Modeling morphology: Solid-solid phase transitions based on colloidal particle shape changes

(Âé¶¹ÒùÔº)—Phase transitions are transformations that occur between states of matter—that is, between solid, liquid, gas, and less commonly between gas and plasma. What may be surprising is that solid-solid phase transitions, ...

Chiral superconductivity experimentally demonstrated for the first time

(Âé¶¹ÒùÔº)—Scientists have found that a superconducting current flows in only one direction through a chiral nanotube, marking the first observation of the effects of chirality on superconductivity. Until now, superconductivity ...

Designing new materials from 'small' data

Finding new functional materials is always tricky. But searching for very specific properties among a relatively small family of known materials is even more difficult.

Theorists propose new class of topological metals with exotic electronic properties

Researchers at Princeton, Yale, and the University of Zurich have proposed a theory-based approach to characterize a class of metals that possess exotic electronic properties that could help scientists find other, similarly-endowed ...

New clues emerge in 30-year-old superconductor mystery

One of the greatest mysteries of experimental physics is how so-called high-temperature superconducting materials work. Despite their name, high-temperature superconductors—materials that carry electrical current with no ...
