The COMPASS Collaboration at CERN has measured diffractive dissociation of 190  GeV/c pions into the π(-)π(-)π(+) final state using a stationary hydrogen target. A partial-wave analysis (PWA) was performed in bins of 3π mass and four-momentum transfer using the...

Role of the Intercrystalline Tie Chains Network in the Mechanical Response of Semicrystalline Polymers.

Physical review letters

Jabbari-Farouji S, Lame O, Perez M, Rottler J, Barrat JL.
PMID: 28598647
Phys Rev Lett. 2017 May 26;118(21):217802. doi: 10.1103/PhysRevLett.118.217802. Epub 2017 May 26.

We examine the microscopic origin of the tensile response in semicrystalline polymers by performing large-scale molecular dynamics simulations of various chain lengths. We investigate the microscopic rearrangements of the polymers during tensile deformation and show that the intercrystalline chain...
