D. Zeb Rocklin - Rigidity percolation in a random tensegrity via analytic graph theory

Tensegrities are mechanical structures that include cable-like elements that are strong and lightweight relative to rigid rods yet support only extensile stress. From suspension bridges to the…

Vladimir Rosenhaus - Feynman rules for wave turbulence

It has long been known that weakly nonlinear field theories can have a late-time stationary state that is not the thermal state, but a wave turbulent state (the Kolmogorov-Zakharov state) with a…
