Structure and dynamics of ring polymers: entanglement effects because of solution density and ring topology
Angelo Rosa, Enzo Orlandini, Luca Tubiana +1
The effects of entanglement in solutions and melts of unknotted ring polymers have been addressed by several theoretical and numerical studies. The system properties have been typi…
Bistable defect structures in blue phase devices
A. Tiribocchi, G. Gonnella, D. Marenduzzo +2
Blue phases (BPs) are liquid crystals made up by networks of defects, or disclination lines. While existing phase diagrams show a striking variety of competing metastable topologie…
Multiscale entanglement in ring polymers under spherical confinement
Luca Tubiana, Enzo Orlandini, Cristian Micheletti
The interplay of geometrical and topological entanglement in semiflexible knotted polymer rings confined inside a spherical cavity is investigated using advanced numerical methods.…
Switching dynamics in cholesteric blue phases
A. Tiribocchi, G. Gonnella, D. Marenduzzo +1
Blue phases are networks of disclination lines, which occur in cholesteric liquid crystals near the transition to the isotropic phase. They have recently been used for the new gene…
Probing the entanglement and locating knots in ring polymers: a comparative study of different arc closure schemes
Luca Tubiana, Enzo Orlandini, Cristian Micheletti
The interplay between the topological and geometrical properties of a polymer ring can be clarified by establishing the entanglement trapped in any portion (arc) of the ring. The t…
Switching and defect dynamics in multistable liquid crystal devices
A. Tiribocchi, G. Gonnella, D. Marenduzzo +1
We investigate the switching dynamics of multistable nematic liquid crystal devices. In particular we identify a remarkably simple 2-dimensional (2D) device which exploits hybrid a…
