23 Nov 2011 | Abstract: | We study the behaviour of confined cubic blue phases under shear flow via
lattice Boltzmann simulations. We focus on the two experimentally observed
phases, blue phase I and blue phase II. The disinclination network of blue
phase II continuously b reaks and reforms under shear, leading to an
oscillatory stress response in time. The oscillations are only regular for very
th in samples. For thicker samples, the shear leads to a "stick-slip" motion of
part of the network along the vorticity direction. Blue phase I responds very
differently: its defect network undergoes seemingly chaotic rearrangements
under shear, irrespective of system size. | Source: | arXiv, 1111.5441 | Services: | Forum | Review | PDF | Favorites |
