Glassy behaviour in phase-separating active matter
Supervised by: Jörg Rottler • January 2018 - July 2018
Stewart Blusson Quantum Matter Institute, University of British Columbia
Vancouver, Canada 
We have worked on a numerical model system of polydisperse active Brownian disks with purely repulsive interparticle harmonic potential, inspired by Fily et al. [Soft Matter 10, 2132-2140 (2014)]. Despite its simplicity, this model displays interesting collective behaviours: motility-induced phase separation (MIPS) [Cates and Tailleur, Annu. Rev. Condens. Matter Phys. 6, 219-244 (2015)] and long-ranged displacement correlations, even on time scales greater than the rotational diffusion time. We showed that the transition from the fluid to the phase separated regime, which characterises MIPS, is accompanied by increased dynamical heterogeneity. Moreover, we provided evidence of an \(r^{-2}\) decay of shear strain correlations on time scales short compared to the rotational diffusion time, both in the dense region of our phase separated system at high activity and in the truly glassy phase [Keta and Rottler, EPL 125, 58004 (2019)]. We attributed the origin of the \(r^{-2}\) decay to elastic interactions that lead to similar behaviour in passive glass formers.

Jamming criticality of spheroids
Supervised by: Peter Olsson • May 2017 - July 2017
Institutionen för fysik, Umeå universitet
Umeå, Sweden 
We adapted models and methods which were initially used to study shear jamming of frictionless soft 2D disks in order to consider 3D ellipsoids, and in particular spheroids — ellispoids of revolution.
- Code developed for the project (mainly C).

Leidenfrost drop impacts on surfaces with micrometric defects
Supervised by: Quentin Ehlinger and Christophe Ybert • June 2016 - July 2016
Institut Lumière Matière, UMR 5306 CNRS, Université Claude Bernard Lyon 1
Lyon, France 
We aimed at using data obtained from drop impacts on single micrometric defects to predict the phenomenology of impacts on more complex networks.
