Synthesis and Characterization of Atomically-Sharp Superconductor-Dielectric Interface
Nathan Sitaraman, Zhaslan Baraissov, Alexis Grassl +4
Modification of superconductor-dielectric interfaces is known to strongly impact coherence times of superconducting quantum devices. This relationship is thought to arise from diff…

Theory of Eliminating Surface Oxides of Superconductors with Noble-Metal Encapsulation
Cristóbal Méndez, Nathan Sitaraman, Matthias Liepe +1
Nanometer-scale surface chemistry limits the performance of SRF cavities and quantum circuits. We present an ab initio framework connecting DFT interfacial energetics with strong-c…

A Computational Picture of Hydride Formation and Dissipation In Nb SRF Cavities
Aiden Harbick, Mark Transtrum, Nathan Sitaraman +2
Research linking surface hydrides to Q-disease, and the subsequent development of methods to eliminate surface hydrides, is one of the great successes of SRF cavity R&D. We use tim…
