Solving a superconducting mystery with more precise computations

Researchers have known about high-temperature superconducting copper-based materials, or cuprates, since the 1980s. Below a certain temperature (approximately -130 degree Celsius), electrical resistance vanishes from these ...

Scientists solve open theoretical problem on electron interactions

Yale-NUS Associate Professor of Science (Physics) Shaffique Adam is the lead author of a recent work that describes a model for electron interaction in Dirac materials, a class of materials that includes graphene and topological ...

16 atomic ions simulate a quantum antiferromagnet

(Phys.org) —Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter that are poorly ...
