Flocking Beyond One Species: Novel Phase Coexistence in a Generalized Two-Species Vicsek Model
Eloise Lardet, Letian Chen, Thibault Bertrand
A hallmark in natural systems, self-organization often stems from very simple interaction rules between individual agents. While single-species self-propelled particle (SPP) system…
Reentrance in a Hamiltonian flocking model
Letian Chen, Luke K. Davis
The clustering of self-motile and repulsive particles, so-called motility-induced phase separation (MIPS), is one of the clearest signatures of active physics. Typically, increasin…
Kinetic theory of pattern formation in a generalized multi-species Vicsek model
Eloise Lardet, Letian Chen, Thibault Bertrand
The theoretical understanding of pattern formation in active systems remains a central problem of interest. Heterogeneous flocks made up of multiple species can exhibit a remarkabl…
S4-Driver: Scalable Self-Supervised Driving Multimodal Large Language Modelwith Spatio-Temporal Visual Representation
Yichen Xie, Runsheng Xu, Tong He +9
The latest advancements in multi-modal large language models (MLLMs) have spurred a strong renewed interest in end-to-end motion planning approaches for autonomous driving. Many en…
