Maximal response to a mechanical leader at critical group size in ant collectives
Atanu Chatterjee, Tom Tzook, Nir Gov +1
It is widely recognized that biological collectives operate near criticality to amplify their capability of collective response. The peak in susceptibility near criticality renders…
The 2024 Motile Active Matter Roadmap
Gerhard Gompper, Howard A. Stone, Christina Kurzthaler +29
Activity and autonomous motion are fundamental aspects of many living and engineering systems. Here, the scale of biological agents covers a wide range, from nanomotors, cytoskelet…
Synergy as the failure of distributivity
Ivan A. Sevostianov, Ofer Feinerman
The concept of emergence, or synergy in its simplest form, is widely used but lacks a rigorous definition. Our work connects information and set theory to uncover the mathematical…
Connecting cooperative transport by ants with the physics of self-propelled particles
Tabea Heckenthaler, Tobias Holder, Ariel Amir +2
Paratrechina longicornis ants are known for their ability to cooperatively transport large food items. Previous studies have focused on the behavioral rules of individual ants and…
Echo chambers in the Ising model and implications on the mean magnetization
Talia Baravi, Ofer Feinerman, Oren Raz
The echo-chamber effect is a common term in opinion dynamic modeling to describe how a person's opinion might be artificially enhanced as it is reflected back at her through social…
Individual crop loads provide local control for collective food intake in ant colonies
Efrat Greenwald, Lior Baltiansky, Ofer Feinerman
Nutritional regulation by ants emerges from a distributed process: food is collected by a small fraction of workers, stored within the crops of individuals, and spreads via local a…
Emergent oscillations assist obstacle negotiation during ant cooperative transport
Aviram Gelblum, Itai Pinkoviezky, Ehud Fonio +2
Collective motion by animal groups is affected by internal interactions, external constraints and the influx of information. A quantitative understanding of how these different fac…
Limits for Rumor Spreading in stochastic populations
Lucas Boczkowski, Ofer Feinerman, Amos Korman +1
Biological systems can share and collectively process information to yield emergent effects, despite inherent noise in communication. While man-made systems often employ intricate…
Individual versus collective cognition in social insects
Ofer Feinerman, Amos Kormanë
The concerted responses of eusocial insects to environmental stimuli are often referred to as collective cognition on the level of the colony.To achieve collective cognitiona group…
The ANTS problem
Ofer Feinerman, Amos Korman
We introduce the Ants Nearby Treasure Search (ANTS) problem, which models natural cooperative foraging behavior such as that performed by ants around their nest. In this problem, k…
Clock Synchronization and Distributed Estimation in Highly Dynamic Networks: An Information Theoretic Approach
Ofer Feinerman, Amos Korman
We consider the External Clock Synchronization problem in dynamic sensor networks. Initially, sensors obtain inaccurate estimations of an external time reference and subsequently c…
Breathe before Speaking: Efficient Information Dissemination Despite Noisy, Limited and Anonymous Communication
Ofer Feinerman, Bernhard Haeupler, Amos Korman
Distributed computing models typically assume reliable communication between processors. While such assumptions often hold for engineered networks, e.g., due to underlying error co…
Fast Rendezvous on a Cycle by Agents with Different Speeds
Ofer Feinerman, Amos Korman, Shay Kutten +1
The difference between the speed of the actions of different processes is typically considered as an obstacle that makes the achievement of cooperative goals more difficult. In thi…
Memory Lower Bounds for Randomized Collaborative Search and Applications to Biology
Ofer Feinerman, Amos Korman
Initial knowledge regarding group size can be crucial for collective performance. We study this relation in the context of the {\em Ants Nearby Treasure Search (ANTS)} problem \cit…
Collaborative search on the plane without communication
Ofer Feinerman, Amos Korman, Zvi Lotker +1
We generalize the classical cow-path problem [7, 14, 38, 39] into a question that is relevant for collective foraging in animal groups. Specifically, we consider a setting in which…
The Physics of Living Neural Networks
Jean-Pierre Eckmann, Ofer Feinerman, Leor Gruendlinger +3
Improvements in technique in conjunction with an evolution of the theoretical and conceptual approach to neuronal networks provide a new perspective on living neurons in culture. O…
String Theory on AdS_3 x S^3 x S^3 x S^1
Shmuel Elitzur, Ofer Feinerman, Amit Giveon +1
Spacetime properties of superstrings on AdS_3 x S^3 x S^3 x S^1 are studied. The boundary theory is a two dimensional superconformal field theory with a large N=(4,4) supersymmetry…
