Rheology of granular liquids in extensional flows: Beyond the -law
Olivier Coquand, Matthias Sperl
The Granular Integration Through Transients (GITT) formalism gives a theoretical description of the rheology of moderately dense granular flows and suspensions. In this work, we ex…
Wrinkling transition in quenched disordered membranes at two loops
O. Coquand, D. Mouhanna
One investigates the flat phase of quenched disordered polymerized membranes by means of a two-loop, weak-coupling computation performed near their upper critical dimension $D_{uc}…
Integration through transients approach to the rheology
Olivier Coquand, Matthias Sperl, Till Kranz
This work generalises the granular integration through transients formalism introduced by Kranz et al. [Phys. Rev. Lett. 121, 148002 (2018)] to the determination of the pressure. W…
The flat phase of polymerized membranes at two-loop order
O. Coquand, D. Mouhanna, S. Teber
We investigate two complementary field-theoretical models describing the flat phase of polymerized - phantom - membranes by means of a two-loop, weak-coupling, perturbative approac…
Temperature Expansions in the Square-Shoulder Fluid I: the Wiener-Hopf Function
O. Coquand, M. Sperl
We investigate the spatial structure of dense square-shoulder fluids. To this end we derive analytical perturbative solutions of the Ornstein-Zernike equation in the low- and high-…
Universal behaviors in the wrinkling transition of disordered membranes
O. Coquand, K. Essafi, J. -P. Kownacki +1
The wrinkling transition experimentally identified by Mutz et al. [Phys. Rev. Lett. 67, 923 (1991)] and then thoroughly studied by Chaieb et al. [Phys. Rev. Lett. 96, 078101 (2006)…
