Splashing transients of 2D plasmons launched by swift electrons

Friday March 3rd, 2017 Hrvoje Buljan 0

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: Kinetochore oscillations in mitotic metaphase

Friday September 16th, 2016 Hrvoje Buljan 0

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 […]

Project: Structure and Dynamics of Exotic Femtosystems (STRUDEF)

Friday September 16th, 2016 Hrvoje Buljan 0

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 […]

Dynamical conductivity and its fluctuations along the crossover to many-body localization

Friday September 16th, 2016 Hrvoje Buljan 0

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 […]
