DOI: 10.1007/s00222-019-00890-5

Abstract: We consider a stochastic aggregation model on $$\mathbb {Z}^d$$Zd. Start with particles distributed according to the product Bernoulli measure with parameter $$\mu $$μ. In addition, start with an aggregate at the origin. Non-aggregated particles move… read more here.

Abstract: Precise control over particle diffusion is promising for diverse modern technologies. Traditionally, particle diffusion is governed by the inherent properties of a liquid medium, limiting versatility and controllability. Here, we report a mechano-diffusion mechanism that… read more here.

DOI: 10.1103/physrevd.109.123025

Abstract: It is commonly believed that the dissipative properties of superdense matter play a negligible role in modeling gravitational waveforms from neutron star inspirals. This study aims to investigate whether this presumption holds true for the… read more here.

DOI: 10.1103/physreve.107.l022101

Abstract: In many-particle diffusions, particles that move the furthest and fastest can play an outsized role in physical phenomena. A theoretical understanding of the behavior of such extreme particles is nascent. A classical model, in the… read more here.

DOI: 10.3390/mi15020199

Abstract: The study of particle diffusion, a classical conundrum in scientific inquiry, holds manifold implications for various real-world applications. Particularly within the domain of active flows, where the motion of self-propelled particles instigates fluid movement, extensive… read more here.
