Various recent studies have revealed amazing phenomena in the dynamics of bacterial colonies where biology meets physics, in particular statistical physics, fluid dynamics, and (soft) con- densed matter. These biological systems reveal analogies with complex fluids (isotropic- nematic phase transitions), spinodal decomposition phenomena in physics and materials sci- ence, and diffusion-limited reaction kinetics in chemistry.

Convection in multiphase fluid flows using lattice Boltzmann methods
Biferale, L., Perlekar, P., Sbragaglia, M. & Toschi, F. (2012). Convection in multiphase fluid flows using lattice Boltzmann methods. Physical Review Letters, 108(10):104502 DOI We present high-resolution numerical simulations of convection in multiphase flows (boiling) using a novel algorithm based on a lattice Boltzmann method. We first study the thermodynamical and kinematic properties of the […]
Inverse energy cascade in three-dimensional isotropic turbulence
Biferale, L., Musacchio, S. & Toschi, F. (2012). Inverse energy cascade in three-dimensional isotropic turbulence. Physical Review Letters, 108(16):164501 DOI We study the statistical properties of homogeneous and isotropic three-dimensional () turbulent flows. By introducing a novel way to make numerical investigations of Navier-Stokes equations, we show that all 3D flows in nature possess a […]
