Volcano transition in a solvable model of frustrated oscillators

B Ottino-Löffler, SH Strogatz - Physical review letters, 2018 - APS
In 1992, a puzzling transition was discovered in simulations of randomly coupled limit-cycle
oscillators. This so-called volcano transition has resisted analysis ever since. It was …

Comparing the locking threshold for rings and chains of oscillators

B Ottino-Löffler, SH Strogatz - Physical Review E, 2016 - APS
We present a case study of how topology can affect synchronization. Specifically, we consider
arrays of phase oscillators coupled in a ring or a chain topology. Each ring is perfectly …

Kuramoto model with uniformly spaced frequencies: Finite- asymptotics of the locking threshold

B Ottino-Löffler, SH Strogatz - Physical Review E, 2016 - APS
We study phase locking in the Kuramoto model of coupled oscillators in the special case where
the number of oscillators, N, is large but finite, and the oscillators' natural frequencies are …

Takeover times for a simple model of network infection

B Ottino-Löffler, JG Scott, SH Strogatz - Physical Review E, 2017 - APS
… The infection spreads only if the node chosen in (b) happens to be infected and its neighbor
… If we set p(f ) to be the front half of the p vector and p(b) to be the back half of p, then we …

[HTML][HTML] Frequency spirals

B Ottino-Löffler, SH Strogatz - Chaos: An Interdisciplinary Journal of …, 2016 - pubs.aip.org
We study the dynamics of coupled phase oscillators on a two-dimensional Kuramoto lattice
with periodic boundary conditions. For coupling strengths just below the transition to global …

Population extinction on a random fitness seascape

B Ottino-Löffler, M Kardar - Physical Review E, 2020 - APS
We explore the role of stochasticity and noise in the statistical outcomes of commonly
studied population dynamics models within a space-independent (mean-field) perspective. …

Seascape origin of Richards growth

DW Swartz, B Ottino-Löffler, M Kardar - Physical Review E, 2022 - APS
First proposed as an empirical rule over half a century ago, the Richards growth equation has
been frequently invoked in population modeling and pandemic forecasting. Central to this …

On Possible Indicators of Negative Selection in Germinal Centers

B Ottino-Loffler, G Victora - arXiv preprint arXiv:2312.05785, 2023 - arxiv.org
… , wherein antibodyproducing B cells undergo evolutionary selection in substructures of
lymph nodes, called germinal centers. While it has been shown that the median B cell affinity …

Spatial competition with interacting agents

B Ottino-Loffler, F Stonedahl, VP Veetil, U Wilensky - 2017 - papers.ssrn.com
We generalize Hotelling’s model of spatial competition with more than two firms in a two-dimensional
space. Firms choose both price and location to maximize profits. The principle of …
