Behind the Paper: Super-Resolution Stimulated X-ray Raman Spectroscopy
We harnessed the noise inherent in typical self-amplified spontaneous emission (SASE) x-ray free-electron laser (XFEL) pulses to demonstrate a nonlinear x-ray spectroscopic tool that circumvents instrumental resolution and beats the Fourier-limit by employing advanced correlation techniques.
Trajectory-based global sensitivity analysis in multiscale models
Introducing a novel global sensitivity analysis (GSA) framework for agent-based models (ABMs) that addresses their unique features. This method enhances understanding of complex dynamics and supports informed decision-making in model development. Read the full paper here.
Measuring Particle Motion Where It Shouldn’t Exist
Our research group recently investigated how fast quantum particles move within a step potential from which they are reflected. The outcome of these experiments helps to improve our understanding of tunnelling phenomena and challenges the Bohmian interpretation of quantum mechanics.
Residue-free wafer-scale direct imprinting of two-dimensional materials
We report a metal stamp imprinting method for patterning 2D films into high quality wafer-scale arrays without introducing chemical or polymer residues. The local contact mode allows some of the 2D material to be selectively exfoliated while leaving 2D arrays on the growth substrate.
Machine-learning design of ductile 2-GPa Alloys
Machine learning enabled the design of 2 GPa ductile alloys with truly uniform elongation. A unique microstructure promotes high work hardening and ductility, overcoming century-long challenges and key limitations of existing ultra-strong alloys.
How Asymmetry in Perovskites Unlocks New Topological States for Light
Perovskites just got a topological upgrade! Our work reveals how symmetry breaking in anisotropic perovskite crystals creates exotic light states with unconventional diabolical points and nonzero Berry curvature paving the way for advanced topological photonics.
