Critical behavior and universality classes for an algorithmic phase transition in sparse reconstruction

Optimization problems with sparsity-inducing penalties exhibit sharp algorithmic phase transitions when the numbers of variables tend to infinity, between regimes of ‘good’ and ‘bad’ performance. The nature of these phase transitions and associated universality classes remain incompletely understood. We analyze the mean field equations from the cavity method for two sparse reconstruction algori...

We use the epsilon expansion to explore a new universality class of second order quantum phase transitions associated with a four-dimensional Yukawa field theory coupled to a traceless Hermitean matrix scalar field. We argue that this class includes four-fermi models in 2 < D < 4 dimensions with SU (N F) × U (N) symmetry and a

Invasion percolation: new algorithms and universality classes

Employing highly efficient algorithms for simulating invasion percolation (IP), whose execution time scales as O[M log(M)] or better for a cluster of M sites, and for determining the backbone of the cluster, we obtain precise estimates for the fractal dimensions of the samplespanning cluster, the backbone, and the minimal path in order to identify the universality classes of four different IP p...

Black holes and universality classes of critical points.

We argue that there exists an infinite class of conformal field theories in diverse dimensions having a universal ratio of the central charge c to the normalized entropy density c. The universality class includes all conformal theories which possess a classical gravity dual according to the AdS/CFT correspondence. From the practical point of view, the universality of c/c provides an explicit te...

Universality classes for horizon instabilities

We introduce a notion of universality classes for the Gregory-Laflamme instability and determine, in the supergravity approximation, the stability of a variety of solutions, including the non-extremal D3-brane, M2-brane, and M5-brane. These three non-dilatonic branes cross over from instability to stability at a certain non-extremal mass. Numerical analysis suggests that the wavelength of the s...
