Relativistic and nonrelativistic spin splitting above and below the Fermi level in a -wave altermagnet
Nicholas Dale, Omar A. Ashour, Marc Vila +8
Nonrelativistic spin splitting (NRSS) challenges conventional wisdom about antiferromagnets by allowing spin-split electronic bands even in collinear orders with zero net magnetiza…
Superconducting Niobium Tip Electron Beam Source
Cameron W. Johnson, Andreas K. Schmid, Marian Mankos +7
Modern electron microscopy and spectroscopy is a key technology for studying the structure and composition of quantum and biological materials in fundamental and applied sciences.…
Near-monochromatic tuneable cryogenic niobium electron field emitter
Cameron W. Johnson, Andreas K. Schmid, Marian Mankos +6
Creating, manipulating, and detecting coherent electrons is at the heart of future quantum microscopy and spectroscopy technologies. Leveraging and specifically altering the quantu…
Inelastic Mach-Zehnder Interferometry with Free Electrons
Cameron W. Johnson, Amy E. Turner, F. Javier García de Abajo +1
We use a novel scanning electron Mach-Zehnder interferometer constructed in a conventional transmission electron microscope to perform inelastic interferometric imaging with free e…
A Scanning 2-Grating Free Electron Mach-Zehnder Interferometer
Cameron W. Johnson, Amy E. Turner, Benjamin J. McMorran
We demonstrate a 2-grating free electron Mach-Zehnder interferometer constructed in a transmission electron microscope. A symmetric binary phase grating and condenser lens system f…
Coherence properties of shallow donor qubits in ZnO
Xiayu Linpeng, Maria L. K. Viitaniemi, Aswin Vishnuradhan +4
Defects in crystals are leading candidates for photon-based quantum technologies, but progress in developing practical devices critically depends on improving defect optical and sp…
