Length-scale selection in adaptive transport networks
Sidney Holden, Mia C. Morrell, Geoffrey Vasil +1
Adaptive transport networks in biological and physical systems exhibit hierarchical organization, characteristic channel spacing, and robust scaling relations. Existing adaptive ne…
The Unsteady Taylor--Vortex Dynamo is Fast
Liam O'Connor, Daniel Lecoanet, Geoffrey M. Vasil +6
Astrophysical and geophysical fluids commonly generate organized magnetic fields, despite having enormous magnetic Reynolds numbers and abundant small-scale turbulence. F…
Divide, Interact, Sample: The Two-System Paradigm
James Chok, Myung Won Lee, Daniel Paulin +1
Mean-field, ensemble-chain, and adaptive samplers have historically been viewed as distinct approaches to Monte Carlo sampling. In this paper, we present a unifying {two-system} fr…
Rapidly Rotating Wall-Mode Convection
Geoffrey M. Vasil, Keaton J. Burns, Daniel Lecoanet +3
In the rapidly rotating limit, we derive a balanced set of reduced equations governing the strongly nonlinear development of the convective wall-mode instability in the interior of…
The solar dynamo begins near the surface
Geoffrey M Vasil, Daniel Lecoanet, Kyle Augustson +5
The Sun's magnetic dynamo cycle features a distinct pattern: a propagating region of sunspot emergence appears around 30 degrees latitude and vanishes near the equator every 11 yea…
Iterative Methods for Navier--Stokes Inverse Problems
Liam O'Connor, Daniel Lecoanet, Evan H. Anders +5
Even when the partial differential equation underlying a physical process can be evolved forward in time, the retrospective (backward in time) inverse problem often has its own cha…
