Time-state superposition in non-equilibrium fluidized granular matter
Marlo Kunzner, W. Till Kranz, Matthias Sperl +1
Despite being intrinsically athermal and strongly driven, granular materials can exhibit remarkably glass-like dynamics. Whether their rheology can be described by the same scaling…
Towards probing velocity distributions in dense granular matter: Utilizing Fiber Bragg Gratings
Marlo Kunzner, Luis Henriques, Fahad Puthalath +8
Granular gases are commonly characterized through their velocity distribution, which provides access to the granular temperature. In experiments, velocity distributions are typical…
Demonstration of domain wall current in MgO-doped lithium niobate single crystals up to 400 °C
Hendrik Wulfmeier, Uliana Yakhnevych, Cornelius Boekhoff +12
Conductive ferroelectric domain walls (DWs) represent a promising topical system for the development of nanoelectronic components and device sensors to be operational at elevated t…
Observing the Glass and Jamming Transitions of Dense Granular Material in Microgravity
Christopher Mayo, Marlo Kunzner, Matthias Sperl +1
The present study investigates a weakly pulsed granular system of polystyrene spheres under long-time microgravity conditions on the International Space Station (ISS). The spheres…
The Dynamics in Vibro-fluidized Beds: A Diffusing Wave Spectroscopy Study
Marlo Kunzner, Christopher Mayo, Matthias Sperl +1
We demonstrate the densification of a granular model system of polystyrene spheres over time by shaking with varying excitation amplitudes or effective temperatures. This densifica…
