Filtering and imaging of frequency-degenerate spin waves using nanopositioning of a single-spin sensor

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Brecht G. Simon, Samer Kurdi, Joris J. Carmiggelt, Michael Borst, Allard Katan | Summary: Nitrogen-vacancy (NV) magnetometry is a new technique for imaging spin waves in magnetic materials. It detects spin waves by their microwave magnetic stray fields, which decay evanescently on the scale of […]

Realization of the Haldane Chern insulator in a moiré lattice

Kavli Affiliate: Jie Shan | First 5 Authors: Wenjin Zhao, Kaifei Kang, Lizhong Li, Charles Tschirhart, Evgeny Redekop | Summary: The Chern insulator displays a quantized Hall effect without Landau levels. In a landmark paper in 1988, Haldane showed that a Chern insulator could be realized through complex next-nearest-neighbor hopping in a honeycomb lattice. Despite […]

Learning to correct spectral methods for simulating turbulent flows

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Gideon Dresdner, Dmitrii Kochkov, Peter Norgaard, Leonardo Zepeda-Núñez, Jamie A. Smith | Summary: Despite their ubiquity throughout science and engineering, only a handful of partial differential equations (PDEs) have analytical, or closed-form solutions. This motivates a vast amount of classical work on numerical simulation of PDEs […]

High-field charge transport and noise in p-Si from first principles

Kavli Affiliate: Austin Minnich | First 5 Authors: David Catherall, Austin Minnich, , , | Summary: The parameter-free computation of charge transport properties of semiconductors is now routine owing to advances in the ab-initio description of the electron-phonon interaction. Many studies focus on the low-field regime in which the carrier temperature equals the lattice temperature […]
