Elastic interactions between topological defects in chiral nematic shells
Alexandre Darmon, Olivier Dauchot, Teresa Lopez-Leon +1
We present a novel, self-consistent and robust theoretical model to investigate elastic interactions between topological defects in liquid crystal shells. Accounting for the non-co…
Topological defects in cholesteric liquid crystal shells
Alexandre Darmon, Michael Benzaquen, Simon Čopar +2
We investigate experimentally and numerically the defect configurations emerging when a cholesteric liquid crystal is confined to a spherical shell. We uncover a rich scenario of d…
AFM study of hydrodynamics in boundary layers around micro- and nanofibers
Julien Dupré de Baubigny, Michael Benzaquen, Caroline Mortagne +7
The description of hydrodynamic interactions between a particle and the surrounding liquid, down to the nanometer scale, is of primary importance since confined liquids are ubiquit…
Capillary levelling of free-standing liquid nanofilms
Mark Ilton, Miles M. P. Couchman, Cedric Gerbelot +6
We report on the capillary-driven levelling of a topographical perturbation at the surface of a free-standing liquid nanofilm. The width of a stepped surface profile is found to ev…
Unravelling the trading invariance hypothesis
Michael Benzaquen, Jonathan Donier, Jean-Philippe Bouchaud
We confirm and substantially extend the recent empirical result of Andersen et al. \cite{Andersen2015}, where it is shown that the amount of risk exchanged in the E-mini S\&P f…
