Launching of plasmons by swift electrons has long been used in electron energy–loss spectroscopy (EELS) to investigate the plasmonic properties of ultrathin, or two-dimensional (2D), electron systems. However, the question of how a swift electron generates plasmons in space and time has never been answered. We address this issue by […]
PROJECT FUNDING: DFG ABSTRACT: During mitosis, sister chromatids connect to microtubules extending from the opposite spindle poles via kinetochores, protein complexes on the chromosome. When a pair of sister kinetochores establishes this configuration, they oscillate around the equatorial plane of the spindle, and the amplitude of these oscillations depends on […]
FUNDING: HRZZ ABSTRACT: The goal of this project is to develop and apply a novel theoretical framework, based on Relativistic Nuclear Energy Density Functional (RNEDF) that enables microscopic modeling of the structure and dynamics of quantum systems at the femtometer scale, and provides accurate predictions for exotic femtosystems far from […]
ABSTRACT: We present a numerical study of the many-body localization (MBL) phenomenon in the high-temperature limit within an anisotropic Heisenberg model with random local fields. Taking the dynamical spin conductivity σ(ω) as the test quantity, we investigate the full frequency dependence of sample-to-sample fluctuations and their scaling properties as a function […]
