The Loss Landscape of Powder X-Ray Diffraction-Based Structure Optimization Is Too Rough for Gradient Descent
Nofit Segal, Akshay Subramanian, Mingda Li +2
Solving crystal structures from powder X-ray diffraction (XRD) is a central challenge in materials characterization. In this work, we study the powder XRD-to-structure mapping usin…
Chimeric states of matter: Meissner effect without superconductivity
Michael J Landry, Mingda Li
Symmetry is central to how we classify phases of matter: solids break spatial translations, superfluids break particle-number conservation, and superconductors "break" gauge symmet…
Magnetic Field-Enhanced Graphene Superconductivity with Record Pauli-Limit Violation
Jixiang Yang, Omid Sharifi Sedeh, Chiho Yoon +22
Spin-polarized superconductors offer a rare platform for studying electronic correlations, but few candidate systems have been experimentally confirmed to date. Here, we report the…
Quantized dislocations for functional and quantum materials
Mingda Li, Ricardo Pablo-Pedro
Dislocations have a profound influence on materials functional properties. In this perspective, we discuss the recent development of quantized dislocations - a theoretical tool tha…
