Particle characterization using THz spectroscopy
Philip Born, Karsten Holldack, Matthias Sperl
THz extinction spectroscopy extends UV-Vis and NIR-spectroscopy to characterize particles from fine powders and dust to sand, grains and granulated materials. We extract particle s…
Multiple higher-order singularities and iso-dynamics in a simple glass-former model
Nicoletta Gnan, Gayatri Das, Matthias Sperl +2
We investigate the slow dynamics of a colloidal model with two repulsive length scales, whose interaction potential is the sum of a hard-core and a square shoulder. Despite the sim…
Glass-Transition Properties from Hard Spheres to Charged Point Particles
Anoosheh Yazdi, Alexei Ivlev, Sergei Khrapak +5
The glass transition is investigated in three dimensions for single and double Yukawa potentials for the full range of control parameters. For vanishing screening parameter, the li…
