Atomic-Scale Structural Fluctuations of a Plasmonic Cavity

Klaus Kern, Anna Maria Roslawska, Abhishek Grewal

Optical spectromicroscopies, which can reach atomic resolution due to plasmonic enhancement, are perturbed by spontaneous intensity modifications. Here, we study such fluctuations in plasmonic electroluminescence at the single-atom limit profiting from the ...

Machine-Learning of Atomic-Scale Properties Based on Physical Principles

Michele Ceriotti, Michael John Willatt

We briefly summarize the kernel regression approach, as used recently in materials modelling, to fitting functions, particularly potential energy surfaces, and highlight how the linear algebra framework can be used to both predict and train from linear fun ...

Incompleteness of Atomic Structure Representations

Michele Ceriotti, Sergey Pozdnyakov, Michael John Willatt

Many-body descriptors are widely used to represent atomic environments in the construction of machine-learned interatomic potentials and more broadly for fitting, classification, and embedding tasks on atomic structures. There is a widespread belief in the ...

Design using randomness: a new dimension for metallurgy

William Curtin

High entropy alloys add a new dimension, atomic-scale randomness and the associated scale-dependent composition fluctuations, to the traditional metallurgical axes of time-temperature-composition-microstructure. Alloy performance is controlled by the energ ...

Tunnelling dynamics between superconducting bound states at the atomic limit

Klaus Kern, Jacob Senkpiel, Haonan Huang

A magnetic impurity is placed on the tip of a scanning tunnelling microscope, allowing direct tunnelling between two Yu-Shiba-Rusinov bound states. This technique can probe and enhance the impurity state lifetime. There is a limit to the miniaturization of ...

Atomic scale symmetry and polar nanoclusters in the paraelectric phase of ferroelectric materials

Dragan Damjanovic, Emad Oveisi, Sina Hashemi Zadeh, Takuya Hoshina

The nature of the "forbidden" local- and long-range polar order in nominally nonpolar paraelectric phases of ferroelectric materials has been an open question since the discovery of ferroelectricity in oxide perovskites (ABO3). A currently considered model ...

Sensitivity Enhancements in Lithium Titanates by Incipient Wetness Impregnation DNP NMR

David Lyndon Emsley, Michael Allan Hope, Pierrick Berruyer, Pinelopi Moutzouri, Snaedis Björgvinsdóttir

Solid-state NMR spectroscopy is a widely used method for investigating structural and electronic properties of inorganic materials, but its use is often limited by low sensitivity. Here, we show how solvent-generated dynamic nuclear polarization can be use ...

Atomic-Scale Dynamics Probed by Photon Correlations

Klaus Kern, Anna Maria Roslawska, Abhishek Grewal

Light absorption and emission have their origins in fast atomic-scale phenomena. To characterize these basic steps (e.g., in photosynthesis, luminescence, and quantum optics), it is necessary to access picosecond temporal and picometer spatial scales simul ...
