389. 【71】Creating The World’s Toughest Obstacle Course for Magnetic Flux Quanta in High-Tc Superconductors

Bernd Aichner (Universität Wien)

Talk

Controlling the movement of magnetic flux quanta in high-temperature superconductors such as YBa2Cu3O7-δ is essential for most applications. It demands the introduction of artificial defect structures that serve as obstacles for the moving flux quanta.
Using a helium ion microscope's well-controllable focused beam, we create ultra-dense periodic patterns of hills and hollows in the potential...

390. 【72】Holographic QCD and the Anomalous Magnetic Moment of the Muon

Talk

The primary source of the estimated error in the standard model's prediction for the anomalous magnetic moment of the muon originates mainly from hadronic vacuum polarization and hadronic light-by-light scattering. The latter is dominated by the exchange of neutral pseudoscalars and axial-vector mesons. By employing holographic QCD, we can compute these contributions and address the problem of...

391. 【73】Understanding complex oxide surfaces at the atomic level through ncAFM and DFT

Talk

Solid oxide compounds constitute the vast majority of all solids on Earth. Their variety is responsible for a wide range of intriguing physical properties, and their abundance opens a possibility for wide-spread technical use. Each solid interacts with the environment through the exposed surfaces, and Surface Science aims to understand these processes and a fundamental level.
The structure of...
