Autonomous Algorithm Discovery for Ptychography via Evolutionary LLM Reasoning
Xiangyu Yin, Ming Du, Junjing Deng +3
Ptychography is a computational imaging technique widely used for high-resolution materials characterization, but high-quality reconstructions often require the use of regularizati…
Adapting General-Purpose Foundation Models for X-ray Ptychography in Low-Data Regimes
Robinson Umeike, Neil Getty, Yin Xiangyu +1
The automation of workflows in advanced microscopy is a key goal where foundation models like Language Models (LLMs) and Vision-Language Models (VLMs) show great potential. However…
Robust Super-Moiré in Large Angle Single-Twist Bilayers
Yanxing Li, Chuqiao Shi, Fan Zhang +19
Forming long wavelength moiré superlattices (MSL) at small-angle twist van der Waals (vdW) bilayers has been a key approach to creating moiré flat bands. The small-angle twist, h…
PEAR: A Robust and Flexible Automation Framework for Ptychography Enabled by Multiple Large Language Model Agents
Xiangyu Yin, Chuqiao Shi, Yimo Han +1
Ptychography is an advanced computational imaging technique in X-ray and electron microscopy. It has been widely adopted across scientific research fields, including physics, chemi…
