Active and passive microrheology with large tracers in hard colloids
Francisco Orts, Manuel Maier, Matthias Fuchs +3
The dynamics of a tracer particle in a bath of quasi-hard colloidal spheres is studied by Langevin dynamics simulations and mode coupling theory (MCT); the tracer radius is varied…
Vibrational phenomena in glasses at low temperatures captured by field theory of disordered harmonic oscillators
Florian Vogel, Matthias Fuchs
We investigate the vibrational properties of topologically disordered materials by analytically studying particles that harmonically oscillate around random positions. Exploiting c…
How are mobility and friction related in viscoelastic fluids?
Juliana Caspers, Nikolas Ditz, Karthika Krishna Kumar +4
The motion of a colloidal probe in a viscoelastic fluid is described by friction or mobility, depending on whether the probe is moving with a velocity or feeling a force. While the…
The BKT Transition and its Dynamics in a Spin Fluid
Thomas Bissinger, Matthias Fuchs
We study the effect of particle mobility on phase transitions in a spin fluid in two dimensions. The presence of a phase transition of the BKT universality class is shown in an off…
Continuum mechanics for the elastic properties of crystals: Microscopic approach based on projection-operator formalism
Florian Miserez, Saswati Ganguly, Rudolf Haussmann +1
We present a microscopic derivation of the laws of continuum mechanics of nonideal ordered solids including dissipation, defect diffusion, and heat transport. Starting point is the…
From viscous fluids to elastic solids: A perspective on the glass transition
Annette Zippelius, Matthias Fuchs
A theory for the non-local stress in liquids captures the crossover from viscous to elastic correlations upon supercooling. It explains the emergence of long-ranged stress fields i…
