Luttinger's theorem at the core of topological matter

In 1960, Joaquin Luttinger introduced a universal statement that relates the total number of particles that a system can accommodate to its behavior under low-energy excitations. While Luttinger's theorem is readily verified ...

Widely accepted Weyl semimetal shown to be a magnetic semiconductor

Weyl semimetals are highly sought after by material scientists. First predicted in the early 2010s, they belong to the class of topological materials that owe their unique transport, optical and thermoelectric behavior to ...

Study offers glimpse of 500-million-year-old sea worm named after 'Dune' monster

Excavations by a University of Kansas paleontologist working in a treasure trove of fossils called the "Spence Shale Lagerstätte" have revealed an ancient sea worm unknown to science until now. The finding has now been published ...

Two mathematicians explain how building bridges within the discipline helped prove Fermat's last theorem

On June 23, 1993, the mathematician Andrew Wiles gave the last of three lectures detailing his solution to Fermat's last theorem, a problem that had remained unsolved for three and a half centuries. Wiles' announcement caused ...

The exciting possibilities of tiny, twisted superconductors

Transporting energy is costly. When a current runs through conductive materials, some of the energy is lost due to resistance as particles within the material interact—just notice the warmth from your phone or laptop. This ...

Similar but different: Antarctic and Arctic sea ice and their responses to climate change

Researchers have used data from previous publications aiming to answer the question of why the Arctic sea ice is responding much more quickly and obviously to climate change than the Antarctic sea ice, which has stayed relatively ...

New kind of quantum transport discovered in a device combining high-temperature superconductors and graphene

Developing new quantum devices relies on controlling how electrons behave. A material called graphene, a single layer of carbon atoms, has fascinated researchers in recent years because its electrons behave as if they have ...
