Reflections from the 2024 Large Language Model (LLM) Hackathon for Applications in Materials Science and Chemistry
Yoel Zimmermann, Adib Bazgir, Zartashia Afzal +141
Here, we present the outcomes from the second Large Language Model (LLM) Hackathon for Applications in Materials Science and Chemistry, which engaged participants across global hyb…
Improved Three-Dimensional Reconstructions in Electron Ptychography through Defocus Series Measurements
Marcel Schloz, Thomas C. Pekin, Hamish G. Brown +9
A detailed analysis of ptychography for 3D phase reconstructions of thick specimens is performed. We introduce multi-focus ptychography, which incorporates a 4D-STEM defocus series…
Roadmap on Data-Centric Materials Science
Stefan Bauer, Peter Benner, Tristan Bereau +58
Science is and always has been based on data, but the terms "data-centric" and the "4th paradigm of" materials research indicate a radical change in how information is retrieved, h…
Electron Ptychography Reveals Correlated Lattice Vibrations at Atomic Resolution
Anton Gladyshev, Benedikt Haas, Thomas C. Pekin +4
In this paper we introduce an electron ptychography reconstruction framework, CAVIAR -- Correlated Atomic Vibration Imaging with sub-Angstrom Resolution -- that reveals an entirely…
Lossy Compression of Electron Diffraction Patterns for Ptychography via Change of Basis
Anton Gladyshev, Thomas C. Pekin, Marcel Schloz +3
Ptychography is a computational imaging technique that has risen in popularity in the x-ray and electron microscopy communities in the past half decade. One of the reasons for this…
Deep Reinforcement Learning for Data-Driven Adaptive Scanning in Ptychography
Marcel Schloz, Johannes Müller, Thomas C. Pekin +2
We present a method that lowers the dose required for a ptychographic reconstruction by adaptively scanning the specimen, thereby providing the required spatial information redunda…
A single-projection three-dimensional reconstruction algorithm for scanning transmission electron microscopy data
Hamish G. Brown, Philipp M. Pelz, Shang-Lin Hsu +13
Increasing interest in three-dimensional nanostructures adds impetus to electron microscopy techniques capable of imaging at or below the nanoscale in three dimensions. We present…
Overcoming information reduced data and experimentally uncertain parameters in ptychography with regularized optimization
Marcel Schloz, Thomas C. Pekin, Zhen Chen +3
The overdetermination of the mathematical problem underlying ptychography is reduced by a host of experimentally more desirable settings. Furthermore, reconstruction of the sample-…
Control of attosecond light polarization in two-color bi-circular fields
Álvaro Jiménez-Galán, Nick Zhavoronkov, David Ayuso +6
We develop theoretically and confirm both numerically and experimentally a comprehensive analytical model which describes the propensity rules in the emission of circularly polariz…
Time-resolved high harmonic spectroscopy of dynamical symmetry breaking in bi-circular laser fields
Álvaro Jiménez-Galán, Nickolai Zhavoronkov, Marcel Schloz +2
The bi-circular scheme for high harmonic generation, which combines two counter-rotating circular fields with frequency ratio 2:1, has recently permitted to generate high harmonics…
