Adaptive rumor propagation and activity contagion in higher-order networks
Mathematical model
As noted, rumor propagation often exhibits higher-order characteristics, relying not only on pairwise interactions but also on complex group-level interactions. In this context, traditional rumor propagation models struggle to…

Invisible quantum waves forge shape-shifting super-materials in real time
Researchers can now observe the phonon dynamics and wave propagation in self-assembly of nanomaterials with unusual properties that rarely exist in nature. This advance will enable researchers to incorporate desired mechanical properties into…

Record-Breaking: Scientists Create Shortest Hard X-Ray Laser Pulses Yet
Researchers used powerful XFELs to trigger strong inner-shell lasing, producing attosecond hard X-ray pulses. Filamentation and Rabi cycling helped explain these effects. Lasers, once confined to the realm of science fiction, are now widely used…

Scientists Achieve “Impossible” Feat in Quantum Measurement
CU Boulder scientists created a quantum device that uses cold atoms and lasers to track 3D acceleration. In a new study, physicists at the University of Colorado Boulder used a cloud of atoms cooled to extremely low temperatures to measure…

Uncovering multiscale structure-property correlations via active learning in scanning tunneling microscopy
Deep Kernel Learning (DKL) Experimental Workflow
Our goal is to develop an efficient way of identifying structural features that host specific physical behavior or that cause (locally) measurable changes in the system’s overall behavior. A…
