Sound waves and the absence of Galilean invariance in flocks
Yuhai Tu, John Toner, Markus Ulm
We study a model of flocking for a very large system (N=320,000) numerically. We find that in the long wavelength, long time limit, the fluctuations of the velocity and density fie…

Worm Structure in Modified Swift-Hohenberg Equation for Electroconvection
Yuhai Tu
A theoretical model for studying pattern formation in electroconvection is proposed in the form of a modified Swift-Hohenberg equation. A localized state is found in two dimension,…
