Temperature Expansions in the Square-Shoulder Fluid I: the Wiener-Hopf Function
O. Coquand, M. Sperl
We investigate the spatial structure of dense square-shoulder fluids. To this end we derive analytical perturbative solutions of the Ornstein-Zernike equation in the low- and high-…
Asymptotically Exact Solution of the Fredrickson-Andersen Model
Koray Önder, Matthias Sperl, W. Till Kranz
The Fredrickson-Andersen (FA) model---a kinetically constrained lattice model---displays an ergodic to non-ergodic transition with a slow two-step relaxation of dynamical correlati…
Glass transition of charged particles in two-dimensional confinement
Anoosheh Yazdi, Marco Heinen, Alexei Ivlev +2
The glass transition of mesoscopic charged particles in two-dimensional confinement is studied by mode-coupling theory. We consider two types of effective interactions between the…
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…
The Glass Transition in Driven Granular Fluids: A Mode-Coupling Approach
W. T. Kranz, M. Sperl, A. Zippelius
We consider the stationary state of a fluid comprised of inelastic hard spheres or disks under the influence of a random, momentum-conserving external force. Starting from the micr…
Single-Particle Dynamics in Dense Granular Fluids under Driving
Matthias Sperl, Wolf Till Kranz, Annette Zippelius
We present a mode-coupling theory for the dynamics of a tagged particle in a driven granular fluid close to the glass transition. The mean-squared displacement is shown to exhibit…
Disconnected Glass-Glass Transitions and Diffusion Anomalies in a Model with two Repulsive Length Scales
Matthias Sperl, Emanuela Zaccarelli, Francesco Sciortino +2
Building on mode-coupling-theory calculations, we report a novel scenario for multiple glass transitions in a purely repulsive spherical potential: the square-shoulder. The liquid-…
The Cole-Cole Law for Critical Dynamics in Glass-Forming Liquids
Matthias Sperl
Within the mode-coupling theory (MCT) for glassy dynamics, the asymptotic low-frequency expansions for the dynamical susceptibilities at critical points are compared to the expansi…
