The fate of the bootstrap percolation hybrid critical point in finite dimension

arXiv:1807.08066 · doi:10.1103/PhysRevLett.122.108301

Abstract

Bootstrap, or -core, percolation displays on the Bethe lattice a mixed first/second order phase transition with both a discontinuous order parameter and diverging critical fluctuations. I apply the recently introduced -layer technique to study corrections to mean-field theory showing that at all orders in the loop expansion the problem is equivalent to a spinodal with quenched disorder. This implies that the mean-field hybrid transition does not survive in physical dimension. Nevertheless, its critical properties as an avoided transition, make it a proxy of the avoided Mode-Coupling-Theory critical point of supercooled liquids.

Discussion of the -layer construction in the Renormalization Group framework added. Accepted for publication on Phys. Rev. Lett
