The 2019 Motile Active Matter Roadmap
Gerhard Gompper, Roland G. Winkler, Thomas Speck +34
Activity and autonomous motion are fundamental in living and engineering systems. This has stimulated the new field of active matter in recent years, which focuses on the physical…
Computational models for active matter
M Reza Shaebani, Adam Wysocki, Roland G Winkler +2
A variety of computational models have been developed to describe active matter at different length and time scales. The diversity of the methods and the challenges in modeling act…
Effective Dynamics of 2D Bloch Electrons in External Fields Derived From Symmetry
E. A. Fajardo, R. Winkler
We develop a comprehensive theory for the effective dynamics of Bloch electrons based on symmetry. We begin with a scheme to systematically derive the irreducible representations (…
Local stress and pressure in an inhomogeneous system of spherical active Brownian particles
Shibananda Das, Gerhard Gompper, Roland G. Winkler
The stress of a fluid on a confining wall is given by the mechanical wall forces, independent of the nature of the fluid being passive or active. At thermal equilibrium, an equatio…
Gate-tunable Electronic Transport in p-type GaSb Quantum Wells
Matija Karalic, Christopher Mittag, Michael Hug +6
We investigate two-dimensional hole transport in GaSb quantum wells at cryogenic temperatures using gate-tunable devices. Measurements probing the valence band structure of GaSb un…
