Active matter with a twist
One of my oldest interests lies in systems that are able to self-propel, like animals or vehicles. Over the years, I have focused on three separate themes that fall under that broad umbrella: Hamiltonian Flocks, Self-Navigating Particles, and Force-Aligning Active Particles. Force-aligning active particles – physics-Controlled robots In recent years, I have collaborated with experimentalists…
Jamming and the energy landscape
Take a bunch of sand grains, pour them into a jar, tap them, and you will get a jammed packing of sand grains, an ensemble of (mostly) repulsive particles that develop an emergent rigidity because of the structure of their contacts. Understanding the diversity and commonalities of jammed packings is one of the longest-standing problems…
Correlated disorder and disordered materials
Draw a bunch of points randomly on a page. Most likely, what you drew is a set of points that are not quite statistically independent, yet not very ordered: this is an example of correlated disorder. Correlated disordered structures have been of great interest in recent years to a large number of communities, from random…
