Arrested States in Persistent Active Matter: Gelation without Attraction
Carl Merrigan, Kabir Ramola, Rakesh Chatterjee +3
We explore phase separation and kinetic arrest in a model active colloidal system consisting of self-propelled, hard-core particles with nonconvex shapes. The passive limit of the…
Kinetically constrained model for gravity-driven granular flow and clogging
Gregory Bolshak, Rakesh Chatterjee, Rotem Lieberman +1
We add extreme driving to the Kob-Andersen kinetically-constrained lattice-gas model in order to mimic the effect of gravity on dense granular systems. For low particle densities,…
Local time of diffusion with stochastic resetting
Arnab Pal, Rakesh Chatterjee, Shlomi Reuveni +1
Diffusion with stochastic resetting has recently emerged as a powerful modeling tool with a myriad of potential applications. Here, we study local time in this model, covering situ…
Motion of active tracer in a lattice gas with cross-shaped particles
Rakesh Chatterjee, Nimrod Segall, Carl Merrigan +3
We analyze the dynamics of an active tracer particle embedded in a thermal lattice gas. All particles are subject to exclusion up to third nearest neighbors on the square lattice,…
Identifying long-term precursors of financial market crashes using correlation patterns
Hirdesh K. Pharasi, Kiran Sharma, Rakesh Chatterjee +3
The study of the critical dynamics in complex systems is always interesting yet challenging. Here, we choose financial market as an example of a complex system, and do a comparativ…
Characterization of catastrophic instabilities: Market crashes as paradigm
Anirban Chakraborti, Kiran Sharma, Hirdesh K. Pharasi +3
Catastrophic events, though rare, do occur and when they occur, they have devastating effects. It is, therefore, of utmost importance to understand the complexity of the underlying…
