Scaling functions for rigidity transitions in disordered systems near 2 dimensions

Invited-In-person  · Invited

Abstract

Critical scaling is often observed near rigidity transitions in soft matter systems. We analyze the critical scaling predicted by an exactly solvable dynamical mean-field theory for an isotropic rigidity transition. We extract renormalization group flows from the exact solution and characterize logarithmic corrections in two dimensions. This allows us to analytically calculate universal scaling functions for all linear response properties in all dimensions for certain kinds of nearly floppy soft matter.
