Physicists find unusual waves in nickel-based magnet
"Such a substance should not be a magnet at all," said Rice's Pengcheng Dai, corresponding author of the study. "And if a neutron scatters off a given nickel ion, the excitations should remain local and not propagate through the sample."

Electronic map reveals 'rules of the road' in superconductor
Twinning in iron selenide made it impossible to obtain clear, whole-sample measurements of nematic order in the material until Rice physicists Pengcheng Dai and Tong Chen published a clever solution to the problem in May. Building on a detwinning technique developed by Dai and colleagues in 2014, Ch

Iron selenide revealed as 'garden-variety iron-based superconductor'
Rice University physicist Pengcheng Dai, corresponding author of a study of the results published online this week in Nature Materials, offered this bottom-line assessment of iron selenide: "It's a garden-variety iron-based superconductor. The fundamental physics of superconductivity are similar to
