Emergence of local geometric laws of step flow in homoepitaxial growth
Ian Johnson, Dionisios Margetis
Below the roughening transition, crystal surfaces exhibit nanoscale line defects, steps, that move by exchanging atoms with their environment. In homoepitaxy, we analytically show…
Real-time interactive 4D-STEM phase-contrast imaging from electron event representation data
Philipp M. Pelz, Ian Johnson, Colin Ophus +2
The arrival of direct electron detectors (DED) with high frame-rates in the field of scanning transmission electron microscopy has enabled many experimental techniques that require…
Multi-tenant Kubernetes Use Cases for AI, Secure Computing and Data Services, and More
Jake Watson, Sadaf R Alam, Christopher Woods +6
Kubernetes, as a container orchestration engine, has been widely used in cloud-native ecosystems for several years. In supercomputing ecosystems, especially where bare-metal perfor…
Mofasa: A Step Change in Metal-Organic Framework Generation
Vaidotas Simkus, Anders Christensen, Steven Bennett +5
Mofasa is an all-atom latent diffusion model with state-of-the-art performance for generating Metal-Organic Frameworks (MOFs). These are highly porous crystalline materials used to…
Spin nilHecke algebras of classical type
Ian Johnson, Weiqiang Wang
We formulate and study the spin nilHecke algebras and of type B/D, which differ from the usual nilHecke al…
