Meso-scale turbulence in living fluids
- H. H. Wensink, J. Dunkel, +4 authors J. Yeomans
- Physics, Medicine
- Proceedings of the National Academy of Sciences
- 20 August 2012
Turbulence is ubiquitous, from oceanic currents to small-scale biological and quantum systems. Self-sustained turbulent motion in microbial suspensions presents an intriguing example of collective… Expand
Dynamical clustering and phase separation in suspensions of self-propelled colloidal particles.
- I. Buttinoni, Julian Bialk'e, F. Kümmel, H. Löwen, C. Bechinger, T. Speck
- Physics, Medicine
- Physical review letters
- 17 May 2013
We study experimentally and numerically a (quasi-)two-dimensional colloidal suspension of self-propelled spherical particles. The particles are carbon-coated Janus particles, which are propelled due… Expand
Melting, freezing and colloidal suspensions
- H. Löwen
- Physics
- 1 February 1994
Abstract Melting and freezing are very common phenomena in everyday life. This review focusses on the statistical mechanics of these ubiquitous phase transitions and highlights recent work on the… Expand
Fundamental-measure free-energy density functional for hard spheres: Dimensional crossover and freezing
- Y. Rosenfeld, M. Schmidt, H. Löwen, P. Tarazona
- Physics
- 1 April 1997
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… Expand
Complex Plasmas and Colloidal Dispersions: Particle-Resolved Studies of Classical Liquids and Solids
- A. Ivlev, H. Löwen, G. Morfill, C. Royall
- Chemistry
- 23 July 2012
Interdisciplinary Research: Scientific Background Basic Properties of Complex Plasmas and Colloidal Dispersions: Charging, Interactions, Major Forces Examples of Particle-Resolved Studies: Static… Expand
Dynamical density functional theory for colloidal dispersions including hydrodynamic interactions
A dynamical density functional theory (DDFT) for translational Brownian dynamics is derived which includes hydrodynamic interactions. The theory reduces to the simple Brownian DDFT proposed by… Expand
Derivation of the phase-field-crystal model for colloidal solidification.
- Sven van Teeffelen, R. Backofen, A. Voigt, H. Löwen
- Materials Science, Physics
- Physical review. E, Statistical, nonlinear, and…
- 19 February 2009
The phase-field-crystal model is by now widely used in order to predict crystal nucleation and growth. For colloidal solidification with completely overdamped individual particle motion, we show that… Expand
Star Polymers Viewed as Ultrasoft Colloidal Particles
- C. N. Likos, H. Löwen, +5 authors D. Richter
- Physics
- 18 May 1998
Combining statistical-mechanical theories and neutron-scattering techniques, we show that the effective pair potential between star polymers is exponentially decaying for large distances and crosses… Expand
Crystallization in a dense suspension of self-propelled particles.
- Julian Bialk'e, T. Speck, H. Löwen
- Materials Science, Physics
- Physical review letters
- 22 December 2011
Using Brownian dynamics computer simulations, we show that a two-dimensional suspension of self-propelled ("active") colloidal particles crystallizes at sufficiently high densities. Compared to the… Expand
PHASE DIAGRAM OF HARD SPHERES CONFINED BETWEEN TWO PARALLEL PLATES
- M. Schmidt, H. Löwen
- Materials Science
- 1 June 1997
A hard sphere system confined between two parallel hard plates is investigated theoretically. Using extensive Monte Carlo computer simulations, the phase diagram is calculated for the whole range of… Expand
