Investigating Jamming percolation using renormalization group methods

ORAL

Abstract

We develop renormalization group-based methods to determine the percolation threshold and exponents for jamming-percolation models. Such models exhibit mixed phase transitions in finite dimensions, with a discontinuous jump in the order parameter and an exponentially diverging length scale: $\xi \approx \exp(|p-p_c^\infty|^\mu)$, where $p_c^\infty$ marks the percolation transition for the infinite system. To extract $p_c^\infty$ we use a Monte-Carlo scheme to find $p_c(L)$ for increasing $L$ and extrapolate to $L\to\infty$. We investigate several models in two dimensions to test for universality of the exponent $\mu$.
