Meso-scale turbulence in living fluids
TLDR
The authors' experimental results for the bacterial flow statistics agree well with predictions from a minimal model for self-propelled rods, suggesting that at high concentrations the collective motion of the bacteria is dominated by short-range interactions.

Dynamical clustering and phase separation in suspensions of self-propelled colloidal particles.
TLDR
A (quasi-)two-dimensional colloidal suspension of self-propelled spherical particles propelled due to diffusiophoresis in a near-critical water-lutidine mixture finds that the driving stabilizes small clusters and undergoes a phase separation into large clusters and a dilute gas phase.

Microscopic theory for the phase separation of self-propelled repulsive disks
Motivated by recent experiments on colloidal suspensions, we study analytically and numerically a microscopic model for self-propelled particles lacking alignment interactions. In this model, even…

Fundamental-measure free-energy density functional for hard spheres: Dimensional crossover and freezing
A geometrically based fundamental-measure free-energy density functional unified the scaled-particle and Percus-Yevick theories for the hard-sphere fluid mixture. It has been successfully applied to…

Derivation of dynamical density functional theory using the projection operator technique.
TLDR
A general dynamical version of density functional theory which involves a generalized diffusion tensor is derived and is given by a Green-Kubo expression for Brownian dynamics of dilute colloidal suspensions.

TLDR
It is found that hydrodynamic interactions damp and slow the dynamics of the confined colloid cluster in comparison to the same situation with neglected hydrod dynamic interactions.

Traveling and resting crystals in active systems.
TLDR
A microscopic field theory for crystallization in active systems is proposed which unifies the phase-field-crystal model of freezing with the Toner-Tu theory for self-propelled particles and provides a starting point for the design of new active materials.

Analytical properties of polaron systems or: Do polaronic phase transitions exist or not?
For more than 40 years it was thought that polaron- and exciton-phonon systems exhibited unexpected localization properties. Particular attention was paid to the so-called phonon-induced…
