Advanced Brain Tissue Imaging with Data-Consistent Diffusion Priors in Laminographic X-Ray Nanoimaging
Wenxuan Fang, Abraham L. Levitan, Ana Diaz +10
Nanoscale imaging of mammalian brains is critical for connectomics. X-ray laminography enables high-throughput imaging of extended, plate-like biological specimens. However, the ti…
Single-shot imaging with randomized structured illumination at a free electron laser
Abraham L. Levitan, Kahraman Keskinbora, Matteo Pancaldi +4
Stroboscopic nanoscale imaging with free electron laser light is revolutionizing our understanding of fast dynamics in heterogeneous systems. The short wavelength of X-ray and extr…
Soft X-ray Reflection Ptychography
Damian Guenzing, Dayne Y. Sasaki, Alexander S. Ditter +9
Scanning transmission X-ray microscopy and ptychography have become mature tools for high-resolution, element-specific imaging of nanoscale structures. However, transmission geomet…
Single-shot X-ray ptychography as a structured illumination method
Abraham Levitan, Klaus Wakonig, Zirui Gao +4
Single-shot ptychography is a quantitative phase imaging method wherein overlapping beams of light arranged in a grid pattern simultaneously illuminate a sample, allowing a full pt…
Signatures of polarized chiral spin disproportionation in rare earth nickelates
Jiarui Li, Robert J. Green, Claribel Domínguez +12
In rare earth nickelates (RENiO), electron-lattice coupling drives a concurrent metal-to-insulator and bond disproportionation phase transition whose microscopic origin has lon…
Nanoscale Domain Wall Dynamics in Micromagnetic Structures with Weak Perpendicular Anisotropy
Tim A. Butcher, Nicholas W. Phillips, Abraham L. Levitan +4
Time-resolved pump-probe soft X-ray ptychography and Scanning Transmission X-ray Microscopy (STXM) were employed to study the magnetic domain wall dynamics in microstructures of pe…
Single-frame far-field diffractive imaging with randomized illumination
Abraham L. Levitan, Kahraman Keskinbora, Umut T. Sanli +2
We introduce a single-frame diffractive imaging method called randomized probe imaging (RPI). In RPI, a sample is illuminated by a structured probe field containing speckles smalle…
