AI-guided high-throughput discovery of iridium- and ruthenium-free palladium-oxide catalysts for durable acidic oxygen evolution
Ken J. Jenewein, Faezeh Habib Zadeh, Xiaoxiao Wang +19
Catalyzing acidic oxygen evolution at the proton-exchange-membrane water electrolysis (PEMWE) anode relies almost entirely on iridium or ruthenium, drawn from concentrated supply c…
Graphlet Histogram Representation Database of Inorganic Crystals
Aaditya Panigrahi, Yanjun Liu, Omri Lesser +2
Machine learning models for materials property prediction increasingly rely on representations learned end-to-end from large density-functional-theory databases, limiting their app…

Omri Lesser, Yanjun Liu, Natalie Maus +11
Predicting the superconducting transition temperature () from crystal structure and composition remains a central challenge in condensed-matter physics, reflecting the absence…
Phase-Separated Charge Order and Twinning Across Length Scales in CsVSb
Jayden Plumb, Andrea Capa Salinas, Krishnanand Mallayya +9
We present X-ray scattering studies resolving structural twinning and phase separation in the charge density wave (CDW) state of the kagome superconductor CsVSb. The three-…
Materials Expert-Artificial Intelligence for Materials Discovery
Yanjun Liu, Milena Jovanovic, Krishnanand Mallayya +5
The advent of material databases provides an unprecedented opportunity to uncover predictive descriptors for emergent material properties from vast data space. However, common reli…
Frustrated charge order and cooperative distortions in ScV6Sn6
Ganesh Pokharel, Brenden R. Ortiz, Linus Kautzsch +7
Here we study the stability of charge order in the kagome metal ScV6Sn6. Synchrotron x-ray diffraction measurements reveal high-temperature, short-range charge correlations at the…

The kagome superconductors KVSb, RbVSb, and CsVSb are known to display charge density wave (CDW) order which impacts the topological characteristics of thei…
Bragg glass signatures in PdErTe with X-ray diffraction Temperature Clustering (X-TEC)
Krishnanand Mallayya, Joshua Straquadine, Matthew Krogstad +6
The Bragg glass phase is a nearly perfect crystal with glassy features predicted to occur in vortex lattices and charge density wave systems in the presence of disorder. Detecting…
Prethermalization, thermalization, and Fermi's golden rule in quantum many-body systems
Krishnanand Mallayya, Marcos Rigol
We study the prethermalization and thermalization dynamics of local observables in weakly perturbed nonintegrable systems, with Hamiltonians of the form , where…
Harnessing Interpretable and Unsupervised Machine Learning to Address Big Data from Modern X-ray Diffraction
Jordan Venderley, Michael Matty, Krishnanand Mallayya +14
The information content of crystalline materials becomes astronomical when collective electronic behavior and their fluctuations are taken into account. In the past decade, improve…
Signatures of quantum phase transitions after quenches in quantum chaotic one-dimensional systems
Asmi Haldar, Krishnanand Mallayya, Markus Heyl +3
Quantum phase transitions are central to our understanding of why matter at very low temperatures can exhibit starkly different properties upon small changes of microscopic paramet…
